Garden Futurist

Alessandro Ossola is a scientist who gets very excited about the challenge of climate change allowing for an opportunity, and he describes it as an historic opportunity for all of us, scientists, gardeners and all types of decision-makers, to really challenge the status-quo and come up with innovative solutions. “Where we can change the narrative though, is we’ve always seen cities, this is true globally, as the foci of extinctions. Both for animals and plants. I really want to change that narrative. I see the city itself as an opportunity to help horticulture, but also biological conservation.” -Alessandro Ossola, PhD, University of California, Davis, CA This content was made possible in part by The Saratoga Horticultural Research Endowment (SHRE).

That’s a really big change, but basically we’re increasing the canopy cover and we’re cooling, we’re greening, we’re storing more carbon. We’re providing all these benefits, and one of the biggest being the wildlife. All the nature that’s coming to this habitat. So that would be my vision for a future that it’s more of a climate-ready landscape, less of the unused grass." Dr. Greg McPherson, research forester with the USDA Forest Service, Pacific Southwest Research Station, emeritus, in Davis, California. #ShareTheShade | #LifeNotLawn This episode was sponsored by: Bartlett Tree Experts

Read the Transcript Article here, which includes links to resources and images from the panel’s presentations. This episode was sponsored by: Bartlett Tree Experts Welcome to Part Two of our special two-part episode of Garden Futurist, called “What Climate Is This?”, with Bart O’Brien, Adrienne St. Clair, Kathleen Norris Brenzel, Glenn Griffith, Ryan Longman, and Dan McKenney. It is part of our series, “Multidisciplinary Approaches to Resilient Landscapes.” If you live in the Pacific region, you know that seasons in your garden look different from the rest of North America. There are many potentially important factors and multiple systems for mapping zones in our region. Ecoregions, microclimates, hardiness, rainfall, soil types, elevation, chill hours, ecology. It goes on and on. You have likely observed that the Pacific Ocean annually influences weather patterns from the coast all the way to the mountains. In an already complex region, climate scientists tell us that extreme changes are underway now. We held a conversation recently with a panel of experts working within the fields of climate science, ecoregion, and hardiness mapping. As we listen to the panelists, we are going to attempt to frame this conversation through a horticultural lens.

Read the Transcript Article Here. This episode was sponsored by: Bartlett Tree Experts Guests David Montgomery and Anne Biklé talk with Garden Futurist about how they have used soil science, history, and storytelling to explore the interconnections between farming practices, how soil health affects the health of crops, how the health of crops influences the health of livestock, and how all of these things affect human health. David Montgomery is a professor at University of Washington, a MacArthur Fellow, and an authority on geomorphology and Anne Biklé is a biologist and environmental planner. They are known for previous books such as The Hidden Half of Nature and for a new book What Your Food Ate.

This conversation with Michael Boland, Chief Park Officer at Presidio Trust in San Francisco, will fill you in on a really exciting in-person event Pacific Horticulture held back in August, when we walked the newly opened Tunnel Tops landscape. “We are finally, finally embracing the Anthropocene…we have to free our minds and accept that nature is not what we were taught it was and that if we are really concerned about biodiversity and about addressing the climate crisis, that we need to think in a completely different way about where nature lives and what it looks like.”

Read the transcript article here. Emmanuel Didier, Principal and Creative Director at Didier Design Studio is a leading figure in public garden design. He speaks to Garden Futurist about representing the steppe biomes of the world as a permanent public garden exhibit and how he works to build ecologically functioning landscapes that also reflect people culturally. Listen to this fresh take on new aesthetics and techniques that will apply to your garden.

When we look at the Willamette Valley, we recognize that we see these remnant giants of Oregon white oak in the landscape. Those Oregon white oaks and the oak savanna have been historically managed with cultural burns since time immemorial. If we can look at the oak savanna—of which about 3 percent remains today, it's an endangered ecosystem, just like the redwoods or old growth forests—we can see that a lot of our native plant relatives like nettles (Urtica) and the prairies of camas (Camassia) that we are in the process of replanting. Judy BlueHorse Skelton is an Assistant Professor in Indigenous Nations Studies at Portland State University.

We’re making space for the social and cultural aspects of horticulture as an experience—and we want to honor the role of individual voices. We spoke with a garden futurist who is working to amplify the voices of underrepresented communities in mainstream garden media, specifically the Black community. Colah B Tawkin is a mother, gardener, and the founder and host of the podcast and media platform known as Black in the Garden. She describes herself as an advocate for Black people trying to reconnect with the land and talks about plants with vigor and volume.

He is the author of many books, including California Plants: A Guide to Our Iconic Flora. “If you are just an average American, and you’re going about your business spewing carbon into the atmosphere, how many trees do you need to plant a year to offset the amount of carbon that you put in the atmosphere? The answer is somewhere around 80, that need to be planted where trees don’t exist.” – Dr. Matt Ritter If you are interested in how to use the SelecTree tool, check out Pacific Horticulture’s recent how-to video on our YouTube channel with Dr. Jenn Yost.

If you take Keystone plants out of your local food web, the food web collapses, because they are producing most of the caterpillars that run that food web. We found that just 5% of our native plant species are supporting 75% of the caterpillars that are out there. Dr. Doug Tallamy is the T. A. Baker Professor of Agriculture in the Department of Entomology and Wildlife Ecology at the University of Delaware. He is known for highly acclaimed books including Bringing Nature Home and Nature’s Best Hope.

With Dr. Nancy Shackelford, Restoration Futures Lab director, and assistant professor of environmental studies at the University of Victoria British Columbia. “In this context, restoration has a lot of meanings. One of those meanings is yes, trying to support the plant species, but it’s also trying to rebuild and support those relationships with people and the practices and the traditions and the histories and the cultures that really existed with those ecosystems. And so in this context, restoration really has a very strong human-nature combination and combined values.” Dr. Nancy Shackelford

Read the companion article here. With Dr. Susan Cordell, Director and Research Ecologist, US Forest Service, Pacific Southwest Research Station, Hilo, Hawai'i. How might a more culturally inclusive viewpoint replace negative historical language associated with invasive plant biology? “In many parts of the world, we cannot uncouple the fact that humans and natural systems are linked and that pristine landscapes are often, in fact, a mirage.” This quote from a paper authored by our guest and colleagues was published recently in Frontiers of Ecology and Evolution. Noticeable right away is that this essay gets very quickly into talking about the language we use when we talk about nature. Our guest and her multi-disciplinary team have taken a unique approach to ecological restoration that considers language and cultural context around how plants in complex ecosystems can be managed. To learn more about Dr. Cordell's work, please read her group's newest paper, inspired by the Liko Nā Pilina experiment: https://www.hawaii.edu/likonapilina/. This is a project using functional traits to promote invasion resistance and native biodiversity. In this perspective, we teamed up with a philosopher to explore the concept and underlying biases towards non-native species.

“There's a surprising portion of the entire natural world of all biodiversity that either rests in or on an oak tree. And another huge portion of biodiversity uses oak trees for food. An oak can produce 3 million acorns in its lifetime, but only a tiny handful of those, if any, will create trees, but those extra acorns are there on the ground waiting to feed just a huge number of organisms from tiny ones all the way up to bears.” Dave Muffly, Senior Arborist and Horticulturist, Santa Barbara, CA.

One of the most innovative things about botanic gardens remains the incredible diversity of plants in one place. In addition to being centers for horticultural education, botanic gardens can use their living collections—often consisting of thousands of plants—to inform research and conservation. Our guest today is Dr. Ari Novy, President & CEO at San Diego Botanic Garden, previously Chief Scientist at Leichtag Foundation, and former Executive Director of the U.S. Botanic Garden in Washington, DC Learn more about the San Diego Botanic Garden, as well as the Pollinator Project collaboration between SDBC and University of California Cooperative Extension.

While some areas of science get a lot of flashy language, Garden Futurist co-producers Sarah Beck and Adrienne St Clair discover that what is happening in the tree research lab may also be described in “explosive” terms. Some of this large-scale research also informs low-tech takeaways that gardeners can use right away. Decisions we make in our home landscapes can have direct impacts to our carbon footprint. Dr. Drew Zwart is a plant pathologist and physiologist at Bartlett Tree Experts. He works out of the Bartlett Tree Research Lab West in San Rafael, California. He explains that while trees that sequester carbon eventually decompose and re-release their carbon into the atmosphere, it’s the services they provide in life—such as shade and irrigation—that leave a net positive impact on the environment.

"Who are the Kim Kardashians in our ecological network?” -Dr. Rachel Meyer So we're really trying to discover which plants really change the whole community network.. We still don't know the rules of complex communities, how they get built, how they're maintained and how they fall apart. And I think eDNA's a rapid way to advance ecological theory about how interdependent we all are on other species.”

“In two to five years, I think there's going to be a lot more known about that jigsaw puzzle. There's an extremely low risk pursuit to do this biodiverse orientated gardening, and it's probably got immune benefits via gut microbiota and other pathways. “ We are talking about the microbiome and Dr. Martin Breed helps us imagine the microscopic, the microbiome inhabits, the soil, the air, and ultimately breaks into our own personal space to connect our bodies to everything around us. Martin Breed is a lecturer in biology at Flinders University, in Adelaide, South Australia. Find his research on Vertical Stratification in Urban Green Space Aerobiomes here.

The Butterflyway Project is the David Suzuki Foundation’s award-winning project led by volunteers, Butterfly Rangers, and helped by residents in local communities, bringing nature home to neighborhoods throughout Canada, one butterfly-friendly planting at a time. Today’s guest, Winnie Hwo, is taking a very particular approach to the problem of insect decline to mobilize people and take action. She is Senior Public Engagement Specialist and one of the David Suzuki Foundation staff responsible for the Butterflyway initiative and is the project lead for British Columbia.

“The younger bracket of people, the demographic that is coming into power…they may actually have more practical impact on this whole issue than all of us aging idealists, the ex-hippies who didn't believe in cars and so on.” Kim Sorvig We hear a somewhat controversial perspective on managing fire risk around homes and properties. We discuss a compelling solution: transitional landscape from human habitation to transitional spaces and then into forest. Our guest, Kim Sorvig, is a research associate professor at the University of New Mexico and a George Pearl fellow, which is an honor given to professionals whose work encourages discourse and positive change in architecture, planning, and historic preservation.

“I don't want to beat people over the head and say, you must conserve all of your water in a bucket, and this is the way to do it. I want them to do it because they want to see that water go down the runnel and they want to see the rain chain and celebrate it.” - Haven Kiers We address multi-dimensional resilient landscapes. Nature HEALS stands for health, engagement, aesthetics, landscapes, and sustainability. Haven Kiers is an assistant professor of Landscape Architecture at UC Davis.

“And when I say ecosystem function, I mean, functions that are important for human survival. This is not just because I think ecology is cool and native plants are neat, but I think I want a world where my children and my grandchildren will survive.” - Tom Kaye We are talking about how wild plant populations are responding to climate change and what humans, both ecologists, and home gardeners, might do to encourage healthy and diverse ecosystems. Tom Kaye is the executive director at the Institute for Applied Ecology in Corvallis, Oregon where his team is working to conserve native species of plants and animals, and doing ecosystem restorations.

“Let's envision that beautiful green future where humans and nature live together in spite of the dense human population that's coming and let's manifest something better.” - Clayton Tschudy Our guest brings us a great example of the challenges and opportunities that are present, where a biodiversity hotspot, and a densely populated human settlement meet. It is radical innovation towards a futurist vision for the integration of humanity and nature. Clayton Tschudy is the executive director of San Diego Canyonlands.
