On January 27, NW RISCC hosted five speakers in a webinar on the impacts of different climate variables on weed biocontrol agents and their success in the Northwest.  Dr. Jenn Andreas began with a brief overview of weed biocontrol. Then Dr. Chandra Moffatt talked about new research re-evaluating the efficacy of Canada's oldest weed biocontrol program, the St. John’s wort (Hypericum perforatum) biocontrol system, across environmental and elevational gradients. Dr. Brittany Barker, and Dr. Fritzi Grevstad discussed phenological drivers and cues, providing a framework for thinking about how climate can interact with insect life cycles to affect voltinism and phenology. Finally, Dr. Annette Evans presented results of a global review of climate impacts on biocontrol.

This event also served as the launching point for a working group to address knowledge gaps around Northwest biocontrol in a changing climate. If you're interested in joining this working group, please fill out this form by Feb. 6, 2026.

On Wednesday, November 19, 2025, in this NW RISCC paired researcher-practitioner webinar, Michele Buonanduci presented the findings of recent research into the impacts of forest and estuary management on the climate resilience of salmon in Washington’s Willapa basin, including the impacts of Spartina eradication. Chad Phillips then provided details about Washington State Department of Agriculture’s Spartina management efforts.

Something Warm in the Water: Temperature, Pathogen, and Invasive Species Impacts on Freshwater Fishes

In this team-up style webinar, Jonny Armstrong presents NW CASC-supported research on trout, temperature, and pathogens in the Upper Klamath Basin, while Ian Tattam discusses the Oregon Department of Fish & Wildlife’s work on non-native bass and juvenile steelhead interactions in the John Day River.
