Phenology is the seasonal timing of events in plants and animals -- when things bloom, leaf out, set seed, fruit, and so on. We can't make plans in the garden without it, and it's steadily changing with warmer temperatures.NEW FROM Empress of Dirt: August Garden Checklist: Tasks & DIY Projects
Three PhD entomologists with UC Cooperative Extension: Sudan Gyawaly, Jhalendra Rijal, and Houston Wilson discuss the phenology and monitoring of the leaffooted and stink bug pest complexes in California nut crops. Including an exciting update from Houston Wilson (UC Riverside) on the trap and lure for leaffooted bug. Stay tuned for part two where the expert panel discusses the integrated management of these pests.More information on controlling plant bugs in almonds and pistachios can be found on the UCIPM website; there are separate pages for stink bugs and leaffooted bugs, and in pistachio, small bugs.Come to an upcoming extension meeting!In the Sacramento Valley:Almond Variety Trials: 2025 Field Meeting at CSU, Chico Farm (TAKE-TWO!) is TOMORROW, Wednesday May 28Prune Research Tour Part 1 is this Thursday, May 29North Sac Valley Groundwater and SGMA is on Tuesday, June 24In the San Joquin Valley: The Almond Board of California is hosting a Production Summit on Wednesday, June 18 where you can hear from researchers on advances in almond production research.The views, thoughts, and opinions expressed are the speaker's own and do not represent the views, thoughts, and opinions of the University of California.

Phenology is a field of study that explains the seasonal changes and behaviors seen in plants and animals. Unfortunately, due to climate change, many phenological events are occurring earlier or later, which disrupts relationships between co-dependent plants and animals. Joining me on the podcast to explain what gardeners need to know about phenology is ecologist and phenology expert Theresa Crimmins.

Exotic annual grasses, or EAGs, are invasive species. They outcompete native grasses. They are extremely flammable. And they are expanding into higher elevations. Targeted sheep grazing is one way to combat these invasive grasses, manage fire risk, and help restore native sagebrush in western states.The EROS team releases weekly EAG maps during the peak green-up in late April to early June, along with annual phenology maps to show the seasonal timing of the green-up. Dr. Kelly Hopping at Boise State University is using these maps to see whether targeted sheep grazing can help manage EAGs. The maps help researchers work with sheep producers to know when is the best time to move the sheep into those areas so their grazing can do the most good. The sheep then, as a part of the team solving the problem of invasive grasses, get to eat in the field when they might not otherwise have grazing available.

Spring is the season when gardeners throw off the hibernation and slumber of months of wet feet, many layers and waterproofs and are reborn anew! The stirring of life in the garden is one of the years great experiences, and makes a gardening life such a worthwhile pursuit, not only is it good for the planet to see the earth greening up, it is also good for the gardeners soul. But there is still lots of hard work to get on with - seeds have to be sown, mulch laid, supports erected and lawns mown. So join Lucy and Saul as they continue their professional gardening lives in the pure heaven that is Spring!Everyone has their indicator that spring is here - some believe the first hint of Hawthorn Blossom is the start, optimists believe that its the first sign of Daffodils, but some wait until the risk of frost has definitely past. Whatever your sign of spring it's definitely an exciting time in the garden as the accelerator pedal of growth slowly fires up the engine on our favourite flowers and plants. So join Lucy and Saul as they talk about their favourite signs of Spring but also discuss some of the practical elements of gardening that for a professional gardener well and truly mean the early part of the gardening season is upon us!LinkedIn link:Saul WalkerInstagram link:Lucy lucychamberlaingardensIntro and Outro music from https://filmmusic.io"Fireflies and Stardust" by Kevin MacLeod (https://incompetech.com)License: CC BY (http://creativecommons.org/licenses/by/4.0/)Support the show

Despite recent declines in some goose populations, fresh data suggest that hunters have reasons to be optimistic about the number of young birds flying south this fall. Dr. Mike Brasher is joined by goose experts Josh Dooley (US Fish and Wildlife Service) and Frank Baldwin (Canadian Wildlife Service) to discuss indices for arctic and subarctic goose populations from Alaska to Atlantic Canada. Many areas experienced early spring and good to excellent conditions for nesting, with multiple indicators suggesting better production than what was experienced a few years in the past. New data and hunter reports from the prairies support these conclusions, so good luck to goose hunters as you head afield.Listen now: www.ducks.org/DUPodcastSend feedback: DUPodcast@ducks.org
