The coming weeks will be busy in the Sacramento Valley, as highly-skilled pilots plant this year’s rice crop. Farmers are no stranger to challenges, and this year is no different. Below-par rain and snowfall have led to water cutbacks of at least 25 percent valley wide, which will lead to an as yet undetermined drop in rice plantings. “There are a lot of fields that won’t be planted on my farm and throughout the state because of a lack of water,” said Sean Doherty, rice grower in Dunningan. “That’s what you do in years like this. You cut back and work with what you have.” Less rice planted has repercussions beyond farms and mills. Rice is an integral part of the Sacramento Valley, providing more than $5 billion to the economy and 25,000 jobs. Rural communities that depend on farming will be impacted, as well as the environment – fewer rice fields planted means less habitat for hundreds of wildlife species.  “Every year, we’re concerned about species that are already listed as threatened, endangered or species of concern,” said Meghan Hertel, Director of Land and Water Conservation at Audubon California. “Unfortunately, in a drought, it’s not just the species of concern that we’re worried about – the ones with the low populations – we’re also worried about common birds.” A recent study from Cornell University study estimates a plunge of the overall bird population by three billion over the last 50 years. She said rice fields are vital for wildlife, especially in a dry year like this one. “Every year, rice fields are important for habitat,” she said. “That’s because, in the Sacramento Valley, we’ve lost 90 to 95 percent of our natural habitat, so much of the ground that birds and other wildlife are using is actually in active rice production. We call it surrogate habitat for birds and wildlife, and in some cases it’s providing two-thirds of the diet of wintering waterfowl.” She said this dry year will mean birds will have to congregate on the fewer acres where water is on the landscape, which means less available food for wildlife. Hertel said there is excellent collaboration in the Sacramento Valley, to support farms and the environment. “Partnerships, communication and collaboration are key. Working together, we can make the best of what we do have.” Collaboration is also a key to helping the state’s struggling salmon population. Jacob Katz, Lead Scientist at Cal Trout has been working with rice farmers and water districts for years now, and said tremendous progress has been made to help salmon. He said rice fields can be used to mimic the incredibly productive wetland habitats that were in the Sacramento Valley before it was developed. “It means slowing water down across the floodplain,” he remarked. “It means spreading it out, creating the puddles that typified the floodplain wetlands before development of the valley, that’s similar to the surrogate wetlands that rice fields are managed as.  What we’ve found is those fields fill up with fish food, with bugs. It only takes three weeks or so to go from a dry field to a shallow, wetland-like environment, and three weeks later it’s teeming with bugs, with fish food. We’ve been working with farmers, water suppliers and reclamation districts to grow the food on these fields, but then to actively drain it back to the river where fish can access it in dry years like this. That’s a really important piece.” “There’s extraordinary room for optimism,” he added. “We’ve shown that the Sacramento Valley can be resilient, can produce benefits for both people and for the environment. Look at the bird response over the last 30 years, as rice growers and water suppliers came together to offer our feathered friends some semblance of the habitat that they evolved in, that they were adapted to. And those birds recognized those flooded rice fields as wetlands…. We can do the same thing for salmon. We have every evidence to suggest that that’s true. That if we hit every link in the salmon’s life history, if we connect their juvenile and adult life phases, we can have a phenomenal response from our fish populations.” Water management is always a balancing act, but the job is especially challenging this year. Thad Bettner is General Manager of the Glenn-Colusa Irrigation District, the largest water district in the Sacramento Valley, spanning 175,000 acres, including rural communities, many rice farms and three federal wildlife refuges.  He is navigating through several subjects, including potential voluntary agreements and water transfers. He said longer term additional water storage would pay major dividends in future dry years. “Water storage would be huge,” he said. “We are looking at Sites Reservoir… we believe the time is now for that. One of the great things about Sites Reservoir is it’s downstream from Shasta Reservoir, so it provides this midstream benefit of being able to regulate the system and really manage for multiple benefits—water supply, meeting the needs of the environment and carryover storage. Sites would help meet all of those goals.” Jim Morris: May in the Sacramento Valley involves an interesting sight - high speed, low flying airplanes planting America's next crop of sushi rice. In fact, I have an airplane heading my way right now! And there is excitement with a new season, but this year is not without its challenges. Welcome to Ingrained the California Rice Podcast. I'm your host, Jim Morris. Proud to have worked with California farmers and ranchers for more than 30 years to help tell their stories. I'm in Sutter County, watching precision GPS guided planting, and it is an amazing site. Even with the benefits rice has to our cuisine, economy and environment, we are not immune from impacts of a dry year. Jim Morris: There will be many things to keep an eye on during this dry year. One of them is the environment. And here in the Sacramento Valley, we're on the Pacific Flyway, so virtually every trip through this area, there are wonderful sites. I was at a farm this morning and they had a bald eagle sighting. So, that's great. However, this dry year won't be easy, not just for the cities and farms, but there are certainly pressure on our diverse ecosystem. Meghan Hertel is director of land and water conservation at Audubon California. And Meghan, as we have this dry year unfold, what are some of your concerns for wildlife? Meghan Hertel: Water is essential, not just for human life, but also for wildlife. And here in California, we have a really interesting water cycle. So the rain falls in fall and winter, and it creates water in the ground, it feeds the habitat and it feeds the wetlands and the rice fields that birds are using. And then most of our waterfall is in the form of snowpack. And that snowpack is released throughout the year and used for our farms and cities, and also to create river flows and to serve the habitats throughout the year. And this year we didn't get rain and we don't have much snowpack. And that means impacts to our habitat and to our wildlife. Jim Morris: Are there particular species you'll keep a watch on as the year unfolds that you're especially concerned about? Meghan Hertel: Every year we're concerned about species that are already listed as threatened or endangered or species of concern. So great examples of this are the salmon, least bell's vireo, from the bird example, or yellow billed cuckoo. Also, the giant garter snake, which we find frequently throughout the Sacramento Valley associated with rice fields and wetlands. But unfortunately in a drought, it's not just the species of concerns we're worried about, the ones with the low populations. We're also worried about common birds. So, Cornell University, last year released a study that showed in the last 50 years we've lost three billion birds, and it's not just the rare ones, it's actually the common birds. So in a year like this, where there'll be less habitat on the ground and less food for birds, we worry about those common birds as well. Jim Morris: How important are rice fields in the equation, particularly when you're looking at a year when there's not going to be a lot of water naturally on the landscape? Meghan Hertel: Well, every year rice fields are important for habitat and that's because in the Sacramento Valley we've lost 90 to 95 percent of our natural habitat. So, much of the ground that birds and other wildlife are using is actually in active rice production. We call it surrogate habitat for birds and wildlife. And in some cases, it's providing two-thirds of the diet of wintering waterfowl. So that's a big amount. Unfortunately in a year like this, we are seeing cutbacks, not just in race, but also in our wetlands. The water system that serves our rice serves our remaining wetlands as well. And so as we see the reduction of habitat, that means birds are going to have to concentrate in fewer areas and they're going to have less food. Jim Morris: One of the ways I hope that is helpful, are these great partnerships between organizations like yourself, rice growers, and other interested parties in the Sacramento Valley. Comment a little bit, please on those partnerships and how valuable they are, particularly in a year like this. Meghan Hertel: Absolutely. Partnerships, communication and collaboration are key. When there are not enough resources, particularly water, that's so important to all of us, to go around, we need to sit down and talk about how we use the limited amount of water that we've got. And that means using science to understand the trade-offs and then maximizing what water we have to reach multiple benefits. And so that's supporting farms, but also saving some water to support habitat, or looking for ways to put water out on the agricultural landscape that both grows food and also supports habitat. The choices won't always be easy, and we certainly are all going to feel a pinch this year and see cutbacks, but by working together, we can make the best of what we do have. Meghan Hertel: One of the things we learned during the last drought, is that it's very important to work together, to come up with scientifically sound collaborative solutions, to put water on the landscape when and where birds needed. A great example of this is the Migratory Bird Conservation Partnership, which is a partnership between Audubon, the Nature Conservancy and Point Blue Conservation Science. We've been working with rice growers and water districts for almost a decade. And when the last drought hit, we were able to put special practices out, putting water on rice fields in spring and early fall to support migratory shorebirds. And there were days where it was the only water on the landscape for birds. And this just shows the importance of collaboration in hard times like drought. Jim Morris: The farm we're at here in Sutter County, is dry, they're working the fields, but it will have rice in it. And this is one of the places that I have seen cattle egrets in their marvelous breeding plumage. It is exciting to see the wildlife. And one of my favorite times is nesting season of shorebirds. Tell me a little bit about that. Obviously there will be a little pressure with less land available, but it is a marvelous sight to see the avocets, stilts, et cetera. So what are your thoughts when you see shorebird nesting? Meghan Hertel: It really gives me hope. It shows that, when we are able to provide habitat here, that nature responds and it wants to have a fighting chance. What we do on the landscape will decide the future of the Central Valley, both for people and birds. And the nesting is a perfect example. So when they are able to find suitable places to nest, that means future generations of birds will be here, and that's a hopeful sign. Jim Morris: It's a very busy time here in the Sacramento Valley rice country with planting underway. I'm with Sean Doherty, a third generation family farmer headquartered here in Dunnigan, near the Yolo Colusa County line. And he farms in Yolo Colusa and Sutter counties with his wife, Melissa, their three kids and famous rice dogs Skeeter and Miss Vegas. So, Sean, what's happening on the farm right now? Sean Doherty: Mainly right now, we are focusing on just putting water on the ground and getting the rice fields ready for water. We are not hurrying like we do in normal years, just because we're just not planning a lot of fields because we don't have the water for them. And so, consequently, we're just getting it done and we're not rushing and we're not working overtime, we're just watching our costs and trying to get this crop in as best we can. There's a lot of fields that aren't getting planted this year across the state, not just on my farm. Jim Morris: When the water goes on to the rice fields and then seeding occurs, people may drive by and they see that water out there, but they may not fully understand the efficiency and the care that's involved in that water. Can you comment a little bit about that? Sean Doherty: That's what we're doing today in these fields right now, in a lot of them as we are going out there and running these GPS controlled drag buckets and leveling our fields to level. And so when we flood it, that way we can cover the soil with as little water as possible. You're talking less than ankle deep. If you don't sink in the mud, just an inch or two skim across these fields is all we need. Jim Morris: You mentioned the muddy conditions out there and I've had a shoe or two lost in a rice field when I didn't wear the right mud boots. So how important is that kind of condition for growing rice and using water efficiently? Sean Doherty: It's bathtub out there. I mean, it holds water like no other soil. You just fill up the soil profile and it doesn't go anywhere. It doesn't go percolate deep underground into the aquifer. In most places, it takes forever to do that. It's just because our ground is heavy, heavy clay, and it's the same type of ground when it gets wet and you try and walk on it and you get 10 pounds of mud on each boot, that's the type of ground that we're growing our crop of rice in. And it's the best ground there is for growing rice because we don't lose the water deep. It just, you're filling up a shallow bowl, like a milk saucer, if you will, with a skim of water and then you're flying your rice seed onto that. And that's what we're working with. So it's really efficient for using that water. And there's a whole lot of multiple efficiencies that we're using across the state here to make the most of our water. Sean Doherty: In my particular irrigation district, where I farm a fair bit of rice, is RD-108. And we have a recirculation system in this district where we can take water from the bottom of the district, and with two pumps, with two lifts, we can take water three quarters of the way back up to the top of the district and we reuse it again. And it allows us to a much more flexibility in these really dry years and to take less water off the river and leave more for the Delta outflows and for fish and for the environment when we operate this recirculation  system. It's not something that you can do year in year out, because you'll have degrading factors with using multiple uses of recycled water, but in these really dry, critically dry years, this is something that we can do to benefit the environment as well. Jim Morris: I'm continually impressed with the diversity of creatures that are out this way. And you've been great to send me photos. And we had a game camera up that captured a lot of the nighttime activity. So you live and work in this environment. Tell me a little bit about the wildlife and some of the things that you see. Sean Doherty: Just this morning, a big flock of pelicans riding the wind, giant garter snakes are the hardest animal to get a picture of, because as soon as you see them on the side of the road or side of the ditch bank and you stop to take their picture, they're gone, they are so fast. Gopher snakes, all kinds of reptiles aplenty. Beavers, otters, wild turkeys, along the riparian corridors alongside where we get our water and where we deliver water out to the fields, pheasants, ducks, shorebirds, herons, cranes, you name it. There's muskrats. I really like being out here and being a rice grower, just because you can see all of that. And I'm happy to provide that for the animals and make a living doing it as well. Jim Morris: And it is going to be a challenge for wildlife too. So, how important are the rice fields this year? Because there's even less opportunities for birds and all the other species that you talked about. It is very helpful to have that rice ecosystem in place. Sean Doherty: I'm worried about having water for the waterfowl this fall and winter coming back into the Valley. And if we don't have the water to put on these fields and these ducks and geese and swans and all the raptors that prey upon those on the flyway, if the habitat doesn't return, I'm worried about what happens to them and the lasting damage it could cause. We have to figure something out, because you can't have the primary wintering habitat for the Pacific Flyway not show up one year. If I'm going to stress about anything more so than the farm, it's what's to happen to the flyway. Jim Morris: I'm in Willows speaking with Thad Bettner, general manager of the Glenn-Colusa Irrigation District, the largest water district in the Sacramento Valley,  covering about 175,000 acres. A significant part of that is rice ground. And GCID recently celebrated their 100th anniversary. And in the time I've known Thad, he's not one to stand still very long, especially in a year like this. So how does your work change during a dry year like this one that we're facing? Thad Bettner: Jim like you said, there's no time to stand still. These years are certainly one of the craziest ones that we face. There's just a lot of work that we have to do both externally and internally, obviously just from an external side, really looking at the drought conditions, how they're affecting the state. We look at things like Shasta Reservoir, status of fisheries, our operations, and then we look internally about, well, what choices are landowners making? How do we serve the multiple needs that we have within our district, from crop needs to environmental needs, to making sure we're being good stewards of the groundwater. So, in a year like this, there's just a lot of decisions that need to be taken into account. And a lot of those decisions happen daily. So it's not just, you can make a decision, expect the rest of the year to play out, but we have to make those decisions on a daily basis. Thad Bettner: We have about 175,000 acres, included in that is the three federal refuges. So working with them and their needs for water and getting water to them on a secure basis is a really important, but then all of our growers who need water from us, we need to make sure they have the information to make the decisions that they want to make this year. In these types of years, we know land is going to have to be idled because we just don't have enough water. So we want to make sure they have the tools to figure out how much land can they farm, what crops do they want to grow this year? How much water do they have to grow those crops? And then, we're also anticipating water transfers actually, which help us with operations and benefit the fishery. Thad Bettner: So, do they want to participate in water transfer? So trying to get all that information out to them so they can make that decision is really important. And then obviously, the decisions they make affects decisions that we then make. And so, it is sort of a process where we have to kind of do a constant level of feedback with them, just to make sure they're up to speed on decisions that we're making and they're making. Jim Morris: Water transfers, as you mentioned very likely this year, how helpful are they in terms of overall water management, including for the environment? Thad Bettner: Well, first look, water transfers are tough. Certainly, there's economic issues resulting from that, there's jobs that may be affected, there are some impacts that water transfers cause. And so I think we want to make sure we're careful in how we consider them as a potential solution to some of our problems. And one of the unique things that water transfers off offer for us as a district, and I think for our customers, is that when we're trying to benefit salmon and particularly this case, winter-run salmon, the thing that we can do with water transfers is, landowners, when they fallow their field, they don't take that water. And what happens is we take that water and we actually leave it behind Shasta Reservoir through the season. And then we move that transfer water in the fall. Thad Bettner: And one of the big benefits that we get is it actually increases the amount of water stored behind Shasta, where it also increases the amount of cold water that’s store behind Shasta. And then that asset can be used to provide cold water downstream to the river, to protect winter-run salmon as they spawn. So, it helps her eggs incubate and then it helps out migrating juveniles. So it really has a huge benefit to the system overall. So, in these types of really tight years, water transfers provide that benefit of being sort of a reasonable balance of protecting fish and then making sure the balance of our lands within the district continue to be farmed. Jim Morris: Another way you protect fish is your amazing fish screen. I believe it's the largest of its kind in the world. Can you comment about that? Thad Bettner: In high school, I used to be able to run a quarter mile in a minute. And so, if you could run that fast, you could basically cover the length of our fish screen. So it is a pretty big feature. I have to say predecessors before me got that project done, it's been in existence now for almost 25 years and it's been just a solid asset for the district. I think one of the interesting things is, as that project came about, there just wasn't a lot of knowledge known about fish screens, how to build them, how to make sure that they would provide a benefit to the species. So, I think our fish screen was kind of one of the first of its kind and really was a test case and a testbed for a lot of decisions that fishery managers had never needed to make before. Thad Bettner: And I think one of the exciting things is, one, that it's been a successful project. And then two, a lot of the other fish screen projects that are built on the Sacramento River, and I think other places in the country, have actually utilized a lot of the information that was gleaned from the actual construction of our project. And as well, some of the adaptive management. It was built, I think they got probably 85 percent of it right, but there was some about 15 percent of things that we've tweaked along the way to make it a better operating facility and continue to provide better protection for fish. And I think those lessons learned have helped other projects again, like in our area and other parts of the United States. Jim Morris: Besides fish, there's also a really vibrant environment in the Sacramento Valley with the Pacific Flyway. How important is it to maintain that environment? Thad Bettner: We take seriously a lot of managing the trade-offs and decisions that we have to make. And certainly continuing to protect the Pacific Flyway and the needs of birds moving up and down this part of the Western US, is important. And the Sac Valley plays a huge part of that. So we talked about fallowing earlier. We don't take lightly the fact that when we fallow lands, a good chunk of that is rice. And so, that's the food that these overwintering birds are relying upon. And so really our goal is to make sure that we leave as much land in production. So, while we're doing transfers, some land's coming out, but really the goal is to keep the maximum that we can to provide that food base for the Pacific Flyway. Thad Bettner: So, when we do years like this, we make sure acreage is spread around. So birds have places to fly. We coordinate with the local refuges and ask them, "Hey, where do you want lands? Where would it be okay to fallow lands or idle lands in here, versus what lands would you want to be in production?" Just because we know that every night you see birds fly off the refuge, they go out and they forage out in the rice lands. And during the day they fly back to the refuge. So the managers know how these birds are moving back and forth locally. So we really tried to make sure as we do some of the fallowing, we're focusing on the needs of the Pacific Flyway and what those birds need. Jim Morris: Our environment is impressive in the Sacramento Valley. I saw two bald eagles this morning in Willows, and we also offer significant habitat for the threatened giant garter snake. So, so glad that this effort is continuing. And in a dry year like this voluntary agreements have come up as a topic of discussion. Can you comment about what they are and how they may help? Thad Bettner: Voluntary agreements is really what we believe is the right solution for the State Water Resources Control Board update of the Bay-Delta Water Quality Control Plan. And the board has really been looking at what they've called their unimpaired flow approach, which is, "Hey, we'll just take a percent of the flow in the river, we'll leave it in the river. And that'll fix a lot of the fishery problems that we have." And we just don't believe it's that simple of a solution to fix. It's a lot more complicated in terms of timing of flow, we need a lot more habitat that we currently don't have. And then we need a solid base of funding to get a lot of these projects done. So we've put together voluntary agreements as a proposal, and as an alternative, and we think our preferred alternative to that unimpaired flow approach, in 2020 the state had put out a proposal, what they believed was a voluntary agreement package. Thad Bettner: And then unfortunately we got COVID, a month and a half later we had fires, and fortunately no floods this year, so we're in drought. But I think we had about everything else pop-up that sort of just distracted us from getting back in the room and trying to get voluntary agreements done. So starting in about August, we got together with the water user community, and we really worked on our own version of what we thought was the right package to move forward and kind of had been working on that and telling the state we're ready to meet with them and kind of waiting for them to get back to us. Thad Bettner: And then oddly enough, right in the midst of a lot of this drought, decision making that we need to do, the state called us week and half ago and said, "Hey, we're ready to start meeting and let's get going on this." So, now as we speak, we're actually starting the conversations back up with the state to see if we can get a voluntary agreement package moving again. And obviously, we're hoping not to do this in the midst of a drought because it just means that we're trying to tackle other problems too, but we're trying to add this to our plate and see if we can't get this done. Jim Morris: Sleep is overrated this year, I guess. So we have the short-term issues that we're talking about, voluntary agreements, water transfers, obviously always maximizing efficiency. Looking longer term, how helpful would additional water storage be and who would benefit from that? Thad Bettner: Water storage would be huge. I think obviously we're looking at Sites Reservoir, one, it sits next to us. We've been involved in this project for decades. So we believe kind of the time is now for that. And I think one of the great things about Sites Reservoir is, it's downstream of Shasta Reservoir. So it kind of provides this middle, midstream benefit and being able to regulate the system and really manage for multiple benefits. So, we've talked about water supply, meeting needs of the environment, carryover storage. So looking at not just this year, but next year. Sites would really help meet all of those goals. So we really think it provides a lot of benefit. And, in a year like this where we're challenged with temperature and flows for a winter-run, Sites Reservoir would help integrating the system and provide those benefits too. Jim Morris: I'm in Knights Landing, one of the areas that's a hotbed for some interesting and promising research to help salmon, not only a key part of our environment, but a key indicator of water issues in our state. Jacob Katz is lead scientist at Cal Trout, an important partner in preserving and enhancing salmon in California. Jacob has a PhD in Ecology from UC Davis. And I have to say, perhaps a greatest opening line, short of “Call me Ishmael,” your bio starts with, “Jacob was born with gills.” That is so cool. And Jacob, pivoting to the dry year we're having, there are some concerns. And what are your thoughts for our Sacramento Valley as we head into a dry year? Jacob Katz: A dry year like this is a tough year to be a salmon. We've got used to the fact that it's our flood years happen maybe every two, maybe four lucky, three out of every 10 years, that prop up our salmon populations. And it's years like this one that are really rough because the Sac River and the other tribs are down low in their levees and those rivers are just real tough places to be a fish, when there's very little habitat, when the water is low and clear and tends to be warm pretty early. So yeah, this is exactly the kind of conditions where we really have to think out of the box, out of the levees, to get those fish as much food and habitat as we can. Jim Morris: How can you do that? Jacob Katz: Well, the field that we're standing in here, Jim, is one that River Garden Farms has been letting us trial some ideas with over the last four or five years. They've been a great partner as have a lot of the other growers in this region on the west side of the river, as well as over on the Sutter side, a lot of folks have been getting together to look at how we can use farm fields to mimic the incredibly productive wetland habitats that were here before the development of the Sac Valley for farms for our rural communities. So what's that mean? It means slowing water down across the floodplain, it means spreading it out. It means really creating the puddles that typified the floodplain wetlands before development of the Valley. Jacob Katz: That's similar to the surrogate wetlands that rice fields are managed as, but what we found is those fields fill up with fish food, with bugs. It only takes three weeks or so to do that, to go from a dry field to a shallow wetland like environment. And three weeks later, it's teeming with bugs, which are essentially fish food. But unlike the ducks and the geese, which have rebounded because of their use of these surrogate wetland habitats, the fish don't have wings. They can't access that fish food out here on the floodplain. And so we've been working with farmers and water suppliers and reclamation districts to grow the food on these fields, but then to actively drain it back to the river where fish can access it in dry years like this. That's a really important piece. Jim Morris: The very field that we're in. I have seen you and your colleague, Jacob Montgomery in there with beakers and the fish food, the zooplankton is absolutely unbelievable. You don't have to guess, you can actually see how much there is in there that could really help the fish. And how important is that this year when it's so dry out there? Jacob Katz: You can just ask the fish, the fish that we have reared in these fields, they swim around with their eyes closed and their mouth open. We call it floating filet if you're a salmon, they are just... They're gorging on the protein production from these fields. These fields are really mimicking the incredible productive capacity of wetlands. Sunlight is being captured by plants, those plants then are broken down by microbes in the shallow water that's out here in a flooded field. Those nutrients then are taken up by bacteria. The bacteria are grazed upon by zooplankton, by small bugs, and those small bugs then are the foundation of the food web for fish. That's how the Valley makes salmon, how it once made salmon. Jacob Katz: And so in a dry year like this, when there's very little out of bank flow in the river, when most of the river flow is stuck within those levees, it's critically important that we reconnect this energy source with the river, that we reconnect the floodplain food web, the energy that comes off these flooded fields back with the river. And that's exactly the program that we've been doing right here with RD-108 and River Garden, where we've been pumping this fish food-rich water back into the river and seeing how fast salmon grow on that Jim Morris: RD-108 meaning, Reclamation District 108, which is about 30 miles north of Sacramento, and a very key player in terms of making things happen to help the environment. And it's going to be a difficult year, but is there reason for optimism when you look at some of the partnerships that have been formed here? Jacob Katz: Oh, there's extraordinary room for optimism. It's already right here. We've shown that the Sac Valley can be resilient, can produce benefits for both people and for the environment. Look at the bird response over the last 30 years, as rice growers and as water suppliers came together to offer our feathered friends some semblance of the habitat that they evolved in, that they were adapted to. And those birds recognized those flooded rice fields as wetlands. And, in the midst of all of this doom and gloom, you hear about the environment. We're here in the Sac Valley, in the midst of this amazing recovery of waterfowl and waterbird populations, where when I was a kid in the Valley 30 years ago, not only was the sky black with smoke, but the birds were at all-time lows. And now, year in and year out, we get these really great counts. Jacob Katz: The work that I've been talking about really can do the same thing for salmon. We have every evidence to suggest that that's true, that if we hit every link in the salmon's life history, in that chain, if we connect their juvenile and their adult life phases, we can have a phenomenal response from our fish populations. We've seen that in Butte Creek, and we can see it again in the Sacramento River, even in dry years like this, if we can re-imagine and re-operate our water and flood infrastructure to mimic natural processes to get this incredible food resource that is now stuck on the dry side of the levees, in these dry years we see that we can make it out here and move it back to the river where the fish can take advantage of it, where they can grow big and strong and have a chance even in dry years like this one. Jim Morris: That wraps up this episode, but we will keep you posted as the year progresses. Thank you to Meghan Hertel, Sean Doherty, Thad Bettner, and Jacob Katz for their time and expertise.

In less than a minute, a large group of young salmon were released into the Sacramento River, en route to the Pacific Ocean. These were no ordinary fish. Equipped with small transmitters, these baby salmon are part of a pilot project by the California Rice Commission and UC Davis. Grown in rice fields of Yolo County, scientists hope to find ways that the farm-raised fish will add to the dwindling wild salmon population. This is part of a larger effort to reconnect the Sacramento Valley flood plains; strategically adding water to the landscape to benefit our environment. “The flood plain is really core to the historical ecology of the Central Valley,” remarked Andrew Rypel, Associate Professor and Peter Moyle and California Trout Chair of Coldwater Fish at the Department of Wildlife, Fish and Conservation Biology at UC Davis. “Once upon a time, before people were over here, there was a lot of water up in the mountains.  The snow would melt in the spring, it would come down and spread out across the central valley. The whole valley was once a huge flood plain. A huge wetland. Abundant Tule plants. Fish, Wildlife. That’s all gone now. But what we do have is we have a lot of rice field habitat, anywhere in the neighborhood of 500,000 acres. We need to figure out how we can use those habitats smartly, to help fish that have evolved using flood plain habitats historically to help boost the populations.” “As many know, fish and farms have often been pitted against each other in California,” Rypel said. “It turns out that they might be able to help each other in the long run.” If the research results are positive, it could eventually lead to many Sacramento Valley rice fields being used to grow salmon each winter. “Ultimately we would like to develop what we would call a conservation practice standard,” said Paul Buttner, Environmental Affairs Manager of the California Rice Commission. “We do this for bird habitat already, where we figure out what we want the growers to do to enhance their fields for habitat. Then we develop a practice that comes with a cost share payment for those that choose to participate.” Here’s a link to find out more about our salmon project, including the sponsors that provide vital support for the research.   Episode Transcript Jim Morris: This is an interesting spot for a field trip. I'm in Knights Landing. To my right is the Sacramento River and to my left are rice fields at River Garden Farms. And there's something unusual this year. There are enclosures raising juvenile salmon. This is year two of our pilot project. Hopefully, the results here will help California’s salmon population in the future. Jim Morris: Welcome to Ingrained, the California Rice Podcast. I'm your host, Jim Morris. At the time of this recording, our world is struggling with COVID-19. My thoughts are with all and my hope is that something positive will come on this front very soon. We're following up on our previous episode, helping salmon. This is year two of the California Rice Commission's Pilot Salmon Project. And today is a big day as salmon raised on this farm are being readied for their journey to the ocean. I'm speaking with Andrew Rypel, who is associate professor and Peter Moyle and California Trout Chair of Coldwater Fish at the Department of Wildlife, Fish and Conservation Biology at UC Davis. So Andrew, it's kind of a big day today in this project. What's happening? Andrew Rypel: We're seeing kind of a culmination of a lot of fieldwork that's happened over the winter here. We've been rearing baby salmon on rice fields for over a month now and they're now finally of size. We're putting transmitters in them and we're tracking them as they make their journey out to the ocean. Jim Morris: And transmitters, I mean, technology has come a long way. So how accurate are they and how much can you learn from these transmitters? Andrew Rypel: They're very accurate. So we're using acoustic transmitters, which means they transmit sound information. I wish we could use GPS tags like they do on turtles and wolves and things like that. But unfortunately, that signal doesn't penetrate water. So we have to use something called acoustic telemetry technology, that's we're putting in these, they're really the smallest available tags on the market and we're putting them in salmon as small as 72 millimeters in length. They transmit sound out into the river and we have an array of receivers deployed in the river, run by NOAA. And the detections are picked up on that array as they make their way out to the ocean. Jim Morris: And how far of a journey is it in terms of length or time? Andrew Rypel: Well, it's out to the Golden Gate and it usually takes them, well it depends on the water year, but anywhere between a few weeks to a couple of months. Usually, in years where it's wet and there's a lot of water in the river, they tend to hold and they don't go out as fast. In years that are a little bit dryer like this one, they tend to get out quicker. Jim Morris: There is not a 100 percent survival rate at a farm or in the wild. And can you talk a little bit about that? There are a lot of challenges if you're a salmon in California. Andrew Rypel: Yeah, that is the crux of the issue here. Survival of juvenile salmon. Out migration, survival into the ocean is low in California. It typically runs anywhere between three to six percent. So that's a lot of death on their way to the ocean. And it's a big reason why salmon populations are struggling in California. There's good information out there. For example, from the Columbia River that suggests that the smolt to adult return rate needs to be around two percent to have a good stable population. And we typically see smolt to adult return ratios in California below one percent. so the amount of survivorship that occurs during this critical part of salmon's life history can really make a difference in having a growing salmon population or a declining salmon population. Andrew Rypel: So what we think is that by rearing salmon on managed floodplain habitat and that's what we're calling rice fields here, they can grow bigger, faster, get out in the river earlier and have increased survivorship that might increase that percentage up a good bit. Jim Morris: Moving forward, there's a lot of effort to reconnect that floodplain. And can you explain what that means? Andrew Rypel: The floodplain is really core to the historical ecology of the Central Valley. Once upon a time, before people were over here, there was a lot of water up in the mountains, the snow would melt in the spring. It would come down and spread out across the Central Valley. And really the whole valley was once a huge flood plain, a huge wetland, abundant Tule plants, fish, wildlife. That's all gone now. But what we do have is we have a lot of rice field habitat, anywhere in the neighborhood of 500,000 acres. So what we really needed to figure out is how we can use those habitats smartly to help fish that have evolved using floodplain habitats historically to help boost the populations. And I love the story because, as many know, fish and farms have often pitted against each other in California and it turns out they might actually be able to help each other in the long run. Jim Morris: But the key for this aspect of it would be rice. Rice is a different crop than others and it works best for this application, is that correct? Andrew Rypel: Rice is basically an agricultural floodplain. It's shallow, it's productive. We're just not using it for fish and wildlife the way we could yet. Jim Morris: So once the tags are done and in and the fish are released, then there's a lot of monitoring. How long does all that take? Andrew Rypel: Well, we'll know some information right away. There are telemetry receiver stations called real time stations that transmit data in real time right to your computer. And you get that just within a week, two weeks, as soon as the fish pass by those receivers. So we'll know some information right away. And then there are what are called autonomous receivers where researchers have to go out in boats, physically get the receivers, download the data from them, and that will take months towards the end of the summer. So we'll know some quick information that's really valuable right away, and then it'll take us a while to learn the whole picture. Jim Morris: And does this speak to the value of the salmon runs? Because this is an incredible effort. Andrew Rypel: I think it does. It is amazing how much research occurs around salmon on the West Coast and particularly in California. And the fact that... It's not just us, there are all sorts of researchers around the Central Valley that are doing salmon telemetry work. And I think that shows how important those survival rates are. We all want to understand why rates are low and what we can do to boost those rates up. Jim Morris: And year one, a lot of storms, year two, not so much and it got warm, but such is life in California, are you still optimistic that there can be something of a success out of all this? Andrew Rypel: I'm very optimistic. This year's work has gone quite well. We've been able to grow the fish like we wanted in the fields we wanted without them flooding and having problems. And what we've seen so far is that the salmon in at River Garden Farms here and then also at Knaggs Ranch, where we're also raising some fish, they've had incredible growth rates. Just like previous research has shown, they've grown super-fast and super-quick. So we're tagging fish right here today that are between 72 and 90 millimeters in length. And then we have a set of fish that we're keeping at the lab that we're going to study later on. Those fish are only measuring in the 50s. So we're talking about just tremendously higher rates of growth in rice field habitat and we're getting those fish out into the system faster and we think that's going to really help their survival. Jim Morris: Paul Buttner is Environmental Affairs Manager for the California Rice Commission. And Paul, why would the Rice Commission work in this area? Paul Buttner: We share the concern over the health of the salmon fishery here in the Sacramento Valley. Historically, these salmon used the floodplain for their rearing. Much of the floodplain is now agricultural fields including rice fields. So we're interested in seeing if we can develop techniques and strategies to essentially reconnect the floodplain by using winter flooded rice fields as salmon habitat. Jim Morris: And assuming that there are good results from the project, how do you see this potentially playing out in terms of growers and helping salmon in the rice fields? Paul Buttner: Well, ultimately we would like to develop what we would call a conservation practice standard. We do this for bird habitat already where we figure out what we want the growers to do to enhance their fields for habitat, and then we develop a practice and it comes with a cost share payment for those that would choose to participate. Jim Morris: And partnerships are critical in getting this thing done. Can you comment about that? Paul Buttner: Yes. This project would not be possible without funding from about a dozen organizations in total, including major contributions by the USDA’s Natural Resources Conservation Service, Syngenta, the SD Bechtel Foundation, Corteva, Grow West and others. Jim Morris: I'm speaking with Rachelle Tallman, UC Davis graduate student who's been integral in this salmon project and last year's as well. And we are under the freeway near the Sacramento River, and what's happening tonight? Rachelle Tallman: Yeah, so we're going to be releasing the fish that we raised at Knaggs Ranch and then a portion of the fish that we raised at River Garden, and we're just kind of timing it with dusk right now. So this is close to seven o'clock and we're going to be taking our Trek, backing it down the ramp and using a slide that we made for the fish to exit more passively than us handling them. Jim Morris: And why at dusk? Rachelle Tallman: We think that it's going to actually increase their chances of survival. In terms of predation, we want to minimize that. You know, when you're putting fish in tanks and getting them prepared to release, they're a little bit stressed out so we're trying to just buy them a little extra chance if we can. Jim Morris: Of course there's still work to be done, but how do you feel? This is kind of a milestone in the project. How are you feeling? Rachelle Tallman: Yeah, it's really exciting to release fish. It means like a portion of the project's done and completed. So I'm excited and I look forward to the second release that we'll do, which will be with more of our River Garden fish and our lab fish from UC Davis. Jim Morris: With the salmon now on their way to the ocean, that will wrap up this episode. Thank you to all of our interview subjects.

Rice fields in the Sacramento Valley are remarkably productive and versatile. From spring into fall, they produce virtually all of America’s sushi rice. In the fall and winter, those same fields are home to millions of birds. What’s next? A promising pilot project could help inform us as to how rice fields can help restore dwindling salmon populations. Throughout the Sacramento Valley, researchers are studying the prospect of reconnecting the historic flood plain, through getting the ‘bug buffet’ found in shallow-flooded rice fields returned to the river to supplement the food supply for migrating salmon.  Additionally, this is year two of an exciting project to raise salmon in rice fields. Through the Rice Commission, UC Davis and California Trout, thousands of juvenile salmon are being raised in rice fields at River Garden Farms in Knights Landing. When they’re ready, these fish will be microchipped and studied as they leave the farm en route to the ocean. Hopefully, this research will pave the way to have rice fields provide the type of boost to salmon that they have for the Pacific Flyway. “What’s incredible is the way the rice industry has decided to mesh with the environment, in such ways that include tracking salmon from Knights Landing all the way to the Golden Gate Bridge. How does that factor in to growing rice, but it does,” remarked Jack Armstrong of the Armstrong & Getty Radio Show, after visiting the pilot project and speaking with participants.  With the vast majority of California’s historic wetlands gone, there’s increased reliance of rice fields as ‘surrogate wetlands,’ not only for birds but perhaps to help salmon, too. “I think they are the difference maker,” said Andrew Rypel, Associate Professor and Peter Moyle Chair of Cold Water Fish Ecology at UC Davis.” If we don’t figure out this problem with rice fields, we’re going to be in a lot worse situation if we lose those rice fields. We really need to figure this out. All of the evidence supports the idea that these are incredible habitats for fish.” The Rice Commission’s Pilot Salmon Project is made possible through sponsors, including the US Department of Agriculture's Natural Resources Conservation Service, Syngenta, The Bechtel Foundation and many others. Here’s a complete list of our valued sponsors. Episode Transcript Jack Armstrong: What's incredible is the way the rice industry has decided to mesh with the environment in such ways that include tracking salmon from night's land in California all the way to the golden gate bridge. How does that factor in with growing rice, but it does. Jim Morris: Jack Armstrong of the Armstrong and Getty Radio Program. Innovation is a hallmark characteristic of California rice and a new chapter is underway, raising salmon and rice fields in an effort to help supplement the state's dwindling fish population. Jim Morris: Welcome to Ingrain, the California rice podcast. I'm your host, Jim Morris. I've been working with farmers and ranchers for 30 years helping tell their stories. Rice is known as the environmental crop and for good reason, millions of birds spend their fall and winter and rice fields. Nearly 230 wildlife species in all live in rice fields. In fact, you might be able to hear the blackbirds in the background here at River Garden Farms in Yolo County where a new chapter is underway. It's a pilot effort to raise salmon in rice fields. It's a windy day here on the farm, but that's actually helpful for researchers in their efforts. I'm with Rachelle Tallman from UC Davis grad student and you're playing a significant role here at the pilot salmon project, and how are things going? Rachelle Tallman: So far, so good. The fish are growing really well out here on the rice fields, warm temperatures and for the most part, good oxygen. So they're doing pretty good. Soon, we might have to start moving things around just because we're starting to enter an early spring. So that's something that we're keeping on the radar. Jim Morris: We've had two years of this. Last year's weather was completely different than this year. So what was the challenge last year and what's the challenge this year? Rachelle Tallman: Yeah, I think last year with all the water we had, the challenge is actually getting to our cages and checking the fish. So it made it really difficult for data collection. This year has been a lot easier data collection wise because again, the bypass is inactive and we're on the dry side of it. The challenging part this year though is because we're not getting the kind of rain or precipitation, we're dealing with warmer temperatures and that's something to be concerned about when we have fish that need to be of a certain size for us to work with them. Jim Morris: So years back, a few years back, did you imagine you would be working in rice fields raising salmon? Rachelle Tallman: No, I definitely knew I was going to be doing salmon, but not in rice fields. That was probably the most unexpected part. Jim Morris: What do you think after you've had a couple of years under your belt with this? Rachelle Tallman: I have so much respect for rice farmers and what they can do because I feel like I've had to take a crash course in how to maintain flow levels and I give huge thanks to River Garden and Conway from last year helping me figure this out because it's a lot more difficult than you think. On paper, it comes off as one way and then when you actually have to implement it, it's really hard. Jim Morris: Obviously, you need to get more information before there is a conclusion, but what are your thoughts about down the road and the role rice fields could play for salmon? Rachelle Tallman: Yeah, I think it's really interesting. This year, we had a new component that we didn't have last year, which was adding habitat complexity to the plots and I'm really interested to see how that impacts survival. There's some data that suggests that once we're putting fish in these fields, they have really high mortality. So it'd be actually very interesting to see what the survival is while we're just growing them and then ultimately, seeing how many can we get to the golden gate. Jim Morris: You talk about some different avenues this year, i.e. Christmas trees in the field, et cetera. What are some of the things that you're doing that you're testing? Rachelle Tallman: Yeah. So with the plots, there's eight of them and there's four treatments. So we have the Christmas trees, canals, Christmas trees and canals, and then we have control groups. We're kind of looking at the growth between the different plots, like the fish growth, as well as a survival to see if there is a difference in doing these treatments or not. Jim Morris: There is a lot of hard work going on here and no one has much downtime. So tell me about some of the activities and all of the hard work here. Rachelle Tallman: Yeah, this project really wouldn't have been possible without the hardworking staff of the Thingy and Rypel Lab, as well as the BioTelemetry group. Each week, we're going out and walking these eight half acre plots, as well as seining them, PIT tagging them and then eventually, we'll be acoustic tagging them. So it really takes an army of people to get this project off the ground. Jim Morris: Seining in particular, looked at especially excruciating. So tell me what seining is for those who don't know. Rachelle Tallman: Yeah, so seining involves a pretty large net and then you have two netters that basically are controlling the ends, and they spread the net out really far and start marching forward. What happens is it kind of corrals the fish into what we call a purse, which is the back of the net. So they kind of work together to try and keep the fish there and then pulling the ends together and sealing it so that we don't lose fish as we're trying to pull the net out of the water. It's physically super intensive. Jim Morris: You also had you called, PIT tagging. So tell me about PIT tagging and what this accomplishes. Rachelle Tallman: Yeah, so PIT tagging, I tell people, it's kind of like when you go to the grocery store and they scan the barcode. It's the same concept except instead of being a barcode printed on a cereal box, we're injecting a tag into the fish and it gives them a unique ID, which is helpful for us because when we are going to figure out survival, we can actually figure out which individuals made it. Jim Morris: This is different than the telemetry tag, if I'm saying the right term, and what is that and when does that come in the process? Rachelle Tallman: So the telemetry tag is really great for us to assess survival to Golden Gate Bridge. The reason we don't do PIT tagging with them is the read range is a little different and as you get closer to a saltier water, it's more difficult to use PIT tag technology. Jim Morris: Amazing with that telemetry information, you literally can know where they end up down the road? Rachelle Tallman: Yeah, we can figure out using statistics like how many actually made it to Golden Gate. Jim Morris: And like anybody, the better your diet, the healthier you're going to be. They are a little healthier right here than compared in a natural river setting? Rachelle Tallman: Yeah, at least compared to the Sac River. The warm temperatures in the rice fields and the high food abundance allows them to grow faster, so they're definitely bigger upon release than a hatchery fish. Jim Morris: To carry out this work, you need cooperative farmers and there are a lot who are interested and excited about this new way to help our environment, that includes Dominic Bruno of River Garden Farms. Dominic Bruno: But we're very optimistic that the efforts that we're helping or that we're putting forward are going to provide good science to really help move these practices and expand these projects and practices across the Valley. Jim Morris: Another key partner is Cal Trout, program manager, Jacob Montgomery logs a lot of miles in Sacramento Valley rice country, including with this project. Jacob Montgomery: Rice fields in the Sutter and in the Yolo Bypass are ideal for this project. All the other rice fields that are outside of the bypasses don't actually have fish that can access them, right? All those rice fields are separated by levies, but in the Yolo and in the Sutter Bypass, as soon as the river gets high enough to inundate and flood those bypasses, it also brings on fish. So those rice fields will hold water for an extended period of time and provide great ponded flood plain fish habitat. Jim Morris: And that is the ultimate goal is to reconnect the flood plain. Can you explain what that will entail hopefully, down the road? Jacob Montgomery: Yeah. So reconnecting the flood plain has two phases really. We want to do this phase that we're calling on the wet side, which is inside the Yolo and in the Sutter Bypasses that this Cal Rice Commission and UC Davis project is testing treatments for. So that part is looking at extending the duration of flooding events that naturally occur in the Yolo Bypass and in the Sutter Bypass, and that's a really important piece. In order to recover the fish populations, we really want to provide them an extended period of flooding time where they can access that habitat and get all of the growth and survival benefits from that habitat. So that's one piece of reconnecting the floodplain. The other piece is integrating those dry side or all of the rice fields outside of the bypass, reconnecting the floodplain resources, which would be primarily fish food. Jacob Montgomery: Since we can't actually get fish out there, what we want to do is flood all those fields, grow a bunch of fish food out there, basically, small water bugs and then drain that water back to the river at the exact time when juvenile salmon are in the system and migrating downstream and naturally doing their sort of growth and survival in rearing thing in the Sacramento River system and provide them an extra subsidy of food resources while they're in the river. Jim Morris: The subsidy of food resources, rice fields are promising on that, correct? Because they are loaded with fish food. Can you explain? Jacob Montgomery: So what happens is when you flood a rice field after harvest, the rice farmers are really doing this for a couple of reasons. The primary one being rice double decomposition, so the water is another way to break down all the leftover rice straw after harvest. They don't have to burn it or bail it or get rid of it in some other way. The other kind of secondary purpose for it is it provides waterfowl habitat, water bird habitat, shorebird habitat. There's the practical aspect for the farming, and the habitat aspect for the birds mostly. And we're adding in this fish benefit because when you flood those rice fields and all that rice straw breaks down, what it breaks down into is basically it turns into a whole bunch of bugs. There's a aquatic food web that emerges to decompose that rice straw and the outcome of that is a hugely abundant and rich biomass of small aquatic bugs that are just the perfect item of food for a fish when it's rearing. Jim Morris: How does the level of those zooplankton, et cetera, in a rice field compare to that of the river and how do you get it from the rice field back to the river? Jacob Montgomery: Yeah, it's a great question. So relatively speaking, the river is a food scarce environment. The way we measure it in the lab is we translate everything to a dry mass and we're talking about micrograms of carbon, that's bugs basically, per cubic meter of water. The river has somewhere between like a hundred and on a good day, maybe 2000 micro grams of carbon per cubic meter of water. The rice fields frequently are over a hundred thousand and I've seen measurements up to four hundred thousand, five hundred thousand micrograms of carbon per cubic meter. So we're talking about anywhere from 200 to 500 times the biomass of food on rice fields as compared to the river. Jacob Montgomery: Second part of that is how do you get that food on the rice fields back to the river? That's relatively simple. So all these rice fields are designed for both irrigation and for drainage. They're all already set up to move water on and move water off and when they move water off, they got to get that water back to the river so they can drain it out completely. It doesn't just form a big flood somewhere. We use all that same infrastructure that the rice farms are using in the summer to irrigate. In the wintertime, we use it to flood and to drain that floodwater, all that floodplain resource generated fish food, back to the river in the exact same way that a rice farmer drains their fields normally. Jim Morris: Is it safe to say that the salmon protection measures of the past haven't worked out too well and we do need to try new avenues or am I overstating that? Jacob Montgomery: Well, I think there are some really good success stories to remember. So one is that of the Butte Creek spring run salmon, that's a classic recovery action where the local group of water managers and farmers and everyone who uses the resource out there got together to coordinate some actions to basically stop diverting water when fish were in the system or screen their diversion so that when they did divert the water, they weren't sucking a bunch of fish out of the system at the same time and upgrade some infrastructures so that there were no barriers to fish access in some of those places. We saw a fantastic response from that fish population after all those actions were completed. There are some stories like that and that's probably one of the better ones, but they're few and far between. So yes, most of the conservation actions I'd say have not been so successful. And I think it's mostly because they're not focusing on the habitat and the population benefit that emerges from having the right habitat at the right time of year for these fish. Jim Morris: Thanks for mentioning Butte Creek. That is a big success story in the Sacramento Valley. So in your professional lifetime, do you feel we will see a market difference in the Valley where these rice fields are actively being utilized for salmon, not only the fish food, but also raising the fish in the winter? Jacob Montgomery: I really hope so. I think it's entirely possible. It's doable right now. I think the hurdles to that are more financial and political than they are logistical as far as physically getting all that floodplain habitat and making it accessible to fish. We need to develop a way to let a farmer keep their land in production and get them credit for the conservation efforts that they make in the winter time when they're not growing rice. If we can figure out a way to do that, then yes, we will absolutely have the Central Valley within 10 years grown tons of fish food and having a big response from our fish populations. Jim Morris: All of this optimism does not erase the fact that there is a long way to go towards a healthy salmon population. Central to this project is Andrew Rypel, associate professor, and Peter Moyle Chair of Coldwater Fish Ecology at UC Davis. He explains the current fish situation in California. Andrew Rypel: So the estimates are somewhere in the neighborhood of 83% of native fishes in California are in some form of decline. Some are extra pay it or completely extinct already. Many are declining and are on their way. So that's the backdrop and challenges we face. Jim Morris: Where do we go from here? What are some of the potential solutions? Andrew Rypel: There's 40 million people in California and there's a lot of activity and those people aren't going anywhere anytime soon. So what we need to do is figure out a smart way to use the habitats that we do have to help fish get better into the future. Jim Morris: We're talking, in this case, about rice fields and we're at river garden farms. Tell me what's happening here and what a level of optimism, perhaps you have that some way, someday down the road that this can make a difference. Andrew Rypel: We are in a rice field and why that's important is that the Central Valley, which is really the hub of fish diversity in California, Central Valley is where a lot of that diversity was historically. All those wetlands are mostly gone. There's only about 5% of those wetlands left, so we really shouldn't be that surprised there's only 5% of the fish left. But what we do have are a lot of these rice fields, anywhere in the neighborhood of 500,000 acres. What we want to do is figure out a smart way to use those habitats for fish. They've been wonderful examples of using these habitats for migratory waterfowl and we're looking at making parallel programs and partnerships to help fish conservation in the future. Jim Morris: There's a long way to go, but how encouraged are you? Before this, we had the New Geary project, so this has been studied for a few years at least and what are some of your initial thoughts about how things are going and if rice fields might be a difference maker? Andrew Rypel: I think they are the difference maker and if we don't figure out this problem with rice fields, we're going to be in a lot worse situation if we lose those rice fields. So we really need to figure this out. All the evidence supports the idea that these are incredible habitats for fish. Whenever we put fish on these habitats, they grow really well, they do really well, but we still need to answer a few more questions that are out there. One of the questions we're interested in is we know they grow fast, but do they actually survive better out to the ocean? Can we wild these fish to be stronger salmon than they were before? If we lose rice fields or they get turned into some other type of crop, we're going to be a lot worse off because then we won't have these wetland aquatic, agricultural floodplains to work with. Jim Morris: There are a lot of positives with this project between the teamwork, expertise and the natural benefits from rice fields, including abundant fish food. This is important work and we will keep you updated on how this pilot project is going. That'll wrap up this episode. Thank you to our interview subjects and those supporting the pilot salmon project, including Syngenta, the US Department of Agriculture's Natural Resources Conservation Service, the Bechtle Foundation, as well as many other valued supporters.

Arcan and OpenBSD, running OpenBSD 6.3 on RPI 3, why C is not a low-level language, HardenedBSD switching back to OpenSSL, how the Internet was almost broken, EuroBSDcon CfP is out, and the BSDCan 2018 schedule is available. Headlines Towards Secure System Graphics: Arcan and OpenBSD Let me preface this by saying that this is a (very) long and medium-rare technical article about the security considerations and minutiae of porting (most of) the Arcan ecosystem to work under OpenBSD. The main point of this article is not so much flirting with the OpenBSD crowd or adding further noise to software engineering topics, but to go through the special considerations that had to be taken, as notes to anyone else that decides to go down this overgrown and lonesome trail, or are curious about some less than obvious differences between how these things “work” on Linux vs. other parts of the world. A disclaimer is also that most of this have been discovered by experimentation and combining bits and pieces scattered in everything from Xorg code to man pages, there may be smarter ways to solve some of the problems mentioned – this is just the best I could find within the time allotted. I’d be happy to be corrected, in patch/pull request form that is 😉 Each section will start with a short rant-like explanation of how it works in Linux, and what the translation to OpenBSD involved or, in the cases that are still partly or fully missing, will require. The topics that will be covered this time are: Graphics Device Access Hotplug Input Backlight Xorg Pledging Missing Installing OpenBSD 6.3 (snapshots) on Raspberry pi 3 The Easy way Installing the OpenBSD on raspberry pi 3 is very easy and well documented which almost convinced me of not writing about it, but still I felt like it may help somebody new to the project (But again I really recommend reading the document if you are interested and have the time). Note: I'm always running snapshots and recommend anybody to do it as well. But the snapshots links will change to the next version every 6 month, so I changed the links to the 6.3 version to keep the blog post valid over times. If you're familiar to the OpenBSD flavors, feel free to use the snapshots links instead. Requirements Due to the lack of driver, the OpenBSD can not boot directly from the SD Card yet, So we'll need an USB Stick for the installtion target aside the SD Card for the U-Boot and installer. Also, a Serial Console connection is required. I Used a PL2303 USB to Serial (TTL) adapter connected to my Laptop via USB port and connected to the Raspberry via TX, RX and GND pins. iXsystems https://www.ixsystems.com/blog/truenas-m-series-veeam-pr-2018/ Why Didn’t Larrabee Fail? Every month or so, someone will ask me what happened to Larrabee and why it failed so badly. And I then try to explain to them that not only didn't it fail, it was a pretty huge success. And they are understandably very puzzled by this, because in the public consciousness Larrabee was like the Itanic and the SPU rolled into one, wasn't it? Well, not quite. So rather than explain it in person a whole bunch more times, I thought I should write it down. This is not a history, and I'm going to skip a TON of details for brevity. One day I'll write the whole story down, because it's a pretty decent escapade with lots of fun characters. But not today. Today you just get the very start and the very end. When I say "Larrabee" I mean all of Knights, all of MIC, all of Xeon Phi, all of the "Isle" cards - they're all exactly the same chip and the same people and the same software effort. Marketing seemed to dream up a new codeword every week, but there was only ever three chips: Knights Ferry / Aubrey Isle / LRB1 - mostly a prototype, had some performance gotchas, but did work, and shipped to partners. Knights Corner / Xeon Phi / LRB2 - the thing we actually shipped in bulk. Knights Landing - the new version that is shipping any day now (mid 2016). That's it. There were some other codenames I've forgotten over the years, but they're all of one of the above chips. Behind all the marketing smoke and mirrors there were only three chips ever made (so far), and only four planned in total (we had a thing called LRB3 planned between KNC and KNL for a while). All of them are "Larrabee", whether they do graphics or not. When Larrabee was originally conceived back in about 2005, it was called "SMAC", and its original goals were, from most to least important: Make the most powerful flops-per-watt machine for real-world workloads using a huge array of simple cores, on systems and boards that could be built into bazillo-core supercomputers. Make it from x86 cores. That means memory coherency, store ordering, memory protection, real OSes, no ugly scratchpads, it runs legacy code, and so on. No funky DSPs or windowed register files or wacky programming models allowed. Do not build another Itanium or SPU! Make it soon. That means keeping it simple. Support the emerging GPGPU market with that same chip. Intel were absolutely not going to build a 150W PCIe card version of their embedded graphics chip (known as "Gen"), so we had to cover those programming models. As a bonus, run normal graphics well. Add as little graphics-specific hardware as you can get away with. That ordering is important - in terms of engineering and focus, Larrabee was never primarily a graphics card. If Intel had wanted a kick-ass graphics card, they already had a very good graphics team begging to be allowed to build a nice big fat hot discrete GPU - and the Gen architecture is such that they'd build a great one, too. But Intel management didn't want one, and still doesn't. But if we were going to build Larrabee anyway, they wanted us to cover that market as well. ... the design of Larrabee was of a CPU with a very wide SIMD unit, designed above all to be a real grown-up CPU - coherent caches, well-ordered memory rules, good memory protection, true multitasking, real threads, runs Linux/FreeBSD, etc. Larrabee, in the form of KNC, went on to become the fastest supercomputer in the world for a couple of years, and it's still making a ton of money for Intel in the HPC market that it was designed for, fighting very nicely against the GPUs and other custom architectures. Its successor, KNL, is just being released right now (mid 2016) and should do very nicely in that space too. Remember - KNC is literally the same chip as LRB2. It has texture samplers and a video out port sitting on the die. They don't test them or turn them on or expose them to software, but they're still there - it's still a graphics-capable part. But it's still actually running FreeBSD on that card, and under FreeBSD it's just running an x86 program called DirectXGfx (248 threads of it). News Roundup C Is Not a Low-level Language : Your computer is not a fast PDP-11. In the wake of the recent Meltdown and Spectre vulnerabilities, it's worth spending some time looking at root causes. Both of these vulnerabilities involved processors speculatively executing instructions past some kind of access check and allowing the attacker to observe the results via a side channel. The features that led to these vulnerabilities, along with several others, were added to let C programmers continue to believe they were programming in a low-level language, when this hasn't been the case for decades. Processor vendors are not alone in this. Those of us working on C/C++ compilers have also participated. What Is a Low-Level Language? Computer science pioneer Alan Perlis defined low-level languages this way: "A programming language is low level when its programs require attention to the irrelevant." While, yes, this definition applies to C, it does not capture what people desire in a low-level language. Various attributes cause people to regard a language as low-level. Think of programming languages as belonging on a continuum, with assembly at one end and the interface to the Starship Enterprise's computer at the other. Low-level languages are "close to the metal," whereas high-level languages are closer to how humans think. For a language to be "close to the metal," it must provide an abstract machine that maps easily to the abstractions exposed by the target platform. It's easy to argue that C was a low-level language for the PDP-11. They both described a model in which programs executed sequentially, in which memory was a flat space, and even the pre- and post-increment operators cleanly lined up with the PDP-11 addressing modes. Fast PDP-11 Emulators The root cause of the Spectre and Meltdown vulnerabilities was that processor architects were trying to build not just fast processors, but fast processors that expose the same abstract machine as a PDP-11. This is essential because it allows C programmers to continue in the belief that their language is close to the underlying hardware. C code provides a mostly serial abstract machine (until C11, an entirely serial machine if nonstandard vendor extensions were excluded). Creating a new thread is a library operation known to be expensive, so processors wishing to keep their execution units busy running C code rely on ILP (instruction-level parallelism). They inspect adjacent operations and issue independent ones in parallel. This adds a significant amount of complexity (and power consumption) to allow programmers to write mostly sequential code. In contrast, GPUs achieve very high performance without any of this logic, at the expense of requiring explicitly parallel programs. The quest for high ILP was the direct cause of Spectre and Meltdown. A modern Intel processor has up to 180 instructions in flight at a time (in stark contrast to a sequential C abstract machine, which expects each operation to complete before the next one begins). A typical heuristic for C code is that there is a branch, on average, every seven instructions. If you wish to keep such a pipeline full from a single thread, then you must guess the targets of the next 25 branches. This, again, adds complexity; it also means that an incorrect guess results in work being done and then discarded, which is not ideal for power consumption. This discarded work has visible side effects, which the Spectre and Meltdown attacks could exploit. On a modern high-end core, the register rename engine is one of the largest consumers of die area and power. To make matters worse, it cannot be turned off or power gated while any instructions are running, which makes it inconvenient in a dark silicon era when transistors are cheap but powered transistors are an expensive resource. This unit is conspicuously absent on GPUs, where parallelism again comes from multiple threads rather than trying to extract instruction-level parallelism from intrinsically scalar code. If instructions do not have dependencies that need to be reordered, then register renaming is not necessary. Consider another core part of the C abstract machine's memory model: flat memory. This hasn't been true for more than two decades. A modern processor often has three levels of cache in between registers and main memory, which attempt to hide latency. The cache is, as its name implies, hidden from the programmer and so is not visible to C. Efficient use of the cache is one of the most important ways of making code run quickly on a modern processor, yet this is completely hidden by the abstract machine, and programmers must rely on knowing implementation details of the cache (for example, two values that are 64-byte-aligned may end up in the same cache line) to write efficient code. Backup URL Hacker News Commentary HardenedBSD Switching Back to OpenSSL Over a year ago, HardenedBSD switched to LibreSSL as the default cryptographic library in base for 12-CURRENT. 11-STABLE followed suit later on. Bernard Spil has done an excellent job at keeping our users up-to-date with the latest security patches from LibreSSL. After recently updating 12-CURRENT to LibreSSL 2.7.2 from 2.6.4, it has become increasingly clear to us that performing major upgrades requires a team larger than a single person. Upgrading to 2.7.2 caused a lot of fallout in our ports tree. As of 28 Apr 2018, several ports we consider high priority are still broken. As it stands right now, it would take Bernard a significant amount of his spare personal time to fix these issues. Until we have a multi-person team dedicated to maintaining LibreSSL in base along with the patches required in ports, HardenedBSD will use OpenSSL going forward as the default cryptographic library in base. LibreSSL will co-exist with OpenSSL in the source tree, as it does now. However, MK_LIBRESSL will default to "no" instead of the current "yes". Bernard will continue maintaining LibreSSL in base along with addressing the various problematic ports entries. To provide our users with ample time to plan and perform updates, we will wait a period of two months prior to making the switch. The switch will occur on 01 Jul 2018 and will be performed simultaneously in 12-CURRENT and 11-STABLE. HardenedBSD will archive a copy of the LibreSSL-centric package repositories and binary updates for base for a period of six months after the switch (expiring the package repos on 01 Jan 2019). This essentially gives our users eight full months for an upgrade path. As part of the switch back to OpenSSL, the default NTP daemon in base will switch back from OpenNTPd to ISC NTP. Users who have localopenntpdenable="YES" set in rc.conf will need to switch back to ntpd_enable="YES". Users who build base from source will want to fully clean their object directories. Any and all packages that link with libcrypto or libssl will need to be rebuilt or reinstalled. With the community's help, we look forward to the day when we can make the switch back to LibreSSL. We at HardenedBSD believe that providing our users options to rid themselves of software monocultures can better increase security and manage risk. DigitalOcean http://do.co/bsdnow -- $100 credit for 60 days How Dan Kaminsky Almost Broke the Internet In the summer of 2008, security researcher Dan Kaminsky disclosed how he had found a huge flaw in the Internet that could let attackers redirect web traffic to alternate servers and disrupt normal operations. In this Hacker History video, Kaminsky describes the flaw and notes the issue remains unfixed. “We were really concerned about web pages and emails 'cause that’s what you get to compromise when you compromise DNS,” Kaminsky says. “You think you’re sending an email to IBM but it really goes to the bad guy.” As the phone book of the Internet, DNS translates easy-to-remember domain names into IP addresses so that users don’t have to remember strings of numbers to reach web applications and services. Authoritative nameservers publish the IP addresses of domain names. Recursive nameservers talk to authoritative servers to find addresses for those domain names and saves the information into its cache to speed up the response time the next time it is asked about that site. While anyone can set up a nameserver and configure an authoritative zone for any site, if recursive nameservers don’t point to it to ask questions, no one will get those wrong answers. We made the Internet less flammable. Kaminsky found a fundamental design flaw in DNS that made it possible to inject incorrect information into the nameserver's cache, or DNS cache poisoning. In this case, if an attacker crafted DNS queries looking for sibling names to existing domains, such as 1.example.com, 2.example.com, and 3.example.com, while claiming to be the official "www" server for example.com, the nameserver will save that server IP address for “www” in its cache. “The server will go, ‘You are the official. Go right ahead. Tell me what it’s supposed to be,’” Kaminsky says in the video. Since the issue affected nearly every DNS server on the planet, it required a coordinated response to address it. Kaminsky informed Paul Vixie, creator of several DNS protocol extensions and application, and Vixie called an emergency summit of major IT vendors at Microsoft’s headquarters to figure out what to do. The “fix” involved combining the 16-bit transaction identifier that DNS lookups used with UDP source ports to create 32-bit transaction identifiers. Instead of fixing the flaw so that it can’t be exploited, the resolution focused on making it take more than ten seconds, eliminating the instantaneous attack. “[It’s] not like we repaired DNS,” Kaminsky says. “We made the Internet less flammable.” DNSSEC (Domain Name System Security Extensions), is intended to secure DNS by adding a cryptographic layer to DNS information. The root zone of the internet was signed for DNSSEC in July 2010 and the .com Top Level Domain (TLD) was finally signed for DNSSEC in April 2011. Unfortunately, adoption has been slow, even ten years after Kaminsky first raised the alarm about DNS, as less than 15 percent of users pass their queries to DNSSEC validating resolvers. The Internet was never designed to be secure. The Internet was designed to move pictures of cats. No one expected the Internet to be used for commerce and critical communications. If people lose faith in DNS, then all the things that depend on it are at risk. “What are we going to do? Here is the answer. Some of us gotta go out fix it,” Kaminsky says.
