Connecting research with practice at the nexus of climate change and invasive species in the Northwest A program of the Northwest Climate Adaptation Science Center @nwcasc.bsky.social and part of the broader RISCC Network www.nwriscc.org

NW RISCC's 2026 research & tool summaries included the following: Jan et al., 2025 discussed the implications of projected decreases in suitable habitat for native bull trout and redband trout with climate change, along with projected increases in niche overlap with non-native predators. Barker et al., 2025 presented new forecasting tools for spotted lanternfly egg hatch and adult appearance dates in the conterminous U.S. Our Tool Summary of the Climate Adaptation Knowledge Exchange (CAKE) provided an introduction to using this interactive, online library of resources for climate adaptation planning and implementation.
A graphic saying, "How to tell if you have a European green crab or something else: Count the number of spines (marginal teeth) next to the eye—European green crabs have five!" and showing photos of the invasive European green crab alongside the native hairy helmet crab, native hairy shore crab, and invasive Chinese mitten crab. Below the identifying graphic, text reads, "Another invasive species featured in our "Don't get crabby, get proactive" management brief, the Chinese mitten crab, made headlines after two separate sightings in Oregon in 2025."

An underwater photo of a rainbow trout surrounded by blue water (image by Jason Ching) serve as the background for white text that says "Something Warm in the Water: Temperature, Pathogen, and Invasive Species Impacts on Freshwater Fishes, Zoom webinar, Tuesday, July 15, 2025, 11 AM–noon (Pacific)." Circular image insets show portraits of the two speakers alongside talk and speaker information, as follows: "Beer and Gasoline Don't Mix—Do Bass and Steelhead? Ian Tattam, Eastern Section Science Program Manager for Oregon Department of Fish & Wildlife" and "Exploring how water temperature and pathogens shape the distribution of native and non-native trout in the Upper Klamath Basin, Jonny Armstrong, Associate Professor, Oregon State University." Also included, in white, are the logos for the Northwest RISCC Management Network & Northwest Climate Adaptation Science Cente.

A banner of images at the top depicts firefighters silhouetted against a blaze, a satellite image of a hurricane, and a tangle of plants on a sand dune.
An illustration of three color morphs of the European green crab (red, dark green, and lighter green) alongside grass, clams, and juvenile Dungeness crabs. Text around and below the illustration reads: Impacts: European green* crab has direct and indirect negative ecological impacts on culturally and economically important PNW species. Destroys aquatic vegetation, including eelgrass (Zostera marina)3 while searching for food, degrading habitat for many species, including salmon, shellfish, and waterfowl. Major predator of clams, mussels, & oysters. Eats & outcompetes juvenile Dungeness crabs (Metacarcinus magister). *They’re not always green! Color varies from red and brown to dark green.
