Our research & tool summaries highlighted research on trout interactions with climate change and nonnative predators (Jan et al., 2025), new forecasting tools for spotted lanternfly (Barker et al., 2025), and the Climate Adaptation Knowledge Exchange. www.nwriscc.org/resources/re...

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.

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.

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."

We're celebrating a year of NW RISCC activities! You can find recordings of our past webinars as well as upcoming ones on our website nwriscc.org/events/webinars You can also find our Management Briefs on invasive freshwater mussels and green crabs nwriscc.org/resources/management-briefs

Graphic saying "Year in Review 2025 Northwest Regional Invasive Species & Climate Change Management Network"

An infographic showing the advertisement slides for NW RISCC's 3 2025 webinars, "Climate-smart invasive species management from coast to coast," "Something warm in the water: temperature, pathogen, and invasive species impacts on freshwater fishes," and "connecting the dots from forest and estuary management to climate-resilient salmon" along with a total of 298 attendees and 316 YouTube views.

An illustration of a quagaga mussel, zebra mussel, and golden mussel, with the text, "from quagga mussels in Idaho to golden mussels in California, the threats of invasive mussels to Northwest waterways have been growing in recent years. Our "Don't move a mussel" management brief explores how climate change can impact these invasions and what we can do about it."

An illustration of three European green crabs with the text, "Our 'Don't get crabby, get proactive' management brief provides an overview of how milder winters and warmer waters can contribute to the spread and establishment of European green crab and includes a quick guide to identification."

The European green crab has known and potential economic, cultural, and ecological impacts in the NW + beyond. Check our latest NW RISCC Management Brief for information on the ways warming temperatures are influencing this ongoing invasion and management efforts: bit.ly/NW_RISCC_briefs

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.
