Wildlife and Plants
Wildlife and plants face many threats from climate change, including increased competition from invasive species, loss of access to freshwater, and shifting air and water temperatures. At the CASCs, researchers study how fish and wildlife are responding to climate change and how resource managers can promote species' adaptation and resilience in the face of shifting conditions.

Science to Help Move From Mortality to Recovery in Western Forests and Woodlands
Healthy forests and woodlands in the western United States provide many important benefits, including providing habitat for wildlife, forage for livestock, and clean water for fish and human use. Yet climate change and other stressors, from wildfires and insect attacks to severe droughts, are causing unprecedented tree die offs across the region, threatening many of these ecosystem services. Follo
Science to Inform Post-fire Conifer Regeneration and Reforestation Strategies Under Changing Climate Conditions
Climate change is causing an increase in the amount of forested area burned by wildfires in the western U.S. The warm, dry post-fire conditions of the region may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Managers are increasingly challenged by the combined impacts of greater wildfire activity, the significant uncertainty about whether forests will
Scoping the Feasibility of Incorporating Climate Change into Risk Assessments of Aquatic Invasive Species in the Upper Midwest
Aquatic invasive species threaten our lakes, streams, and wetlands. These species not only change the biology within the waterbody, but they can change the way we use those waterbodies and the resources they produce. Those changes may have large economic impacts, such as direct management costs and indirect costs to fisheries, tourism and commerce. These species can be small like zebra mussels or
The Impact of Future Changes in Climate on Breeding Waterfowl Pairs in the US Prairie Pothole Region
The Prairie Pothole Region is recognized as one of the most critical breeding habitats for waterfowl in North America and is used by an estimated 50–80 % of the continent’s breeding duck population. The ongoing acquisition program of the U.S. Fish and Wildlife Service National Wildlife Refuge System has conserved approximately 1.3 million hectares of critical breeding-waterfowl habitat. This curre
The Impact of Future Climate on Wetland Habitat in a Critical Migratory Waterfowl Corridor of the Prairie Pothole Region
The Prairie Pothole Region is recognized as one of the most productive areas for waterfowl in North America and supports an estimated 50–80 % of the continent’s duck population. This important habitat is threatened by climate change and continued land-use change. The goal of this research is to establish a framework for assessing future impacts of climate and land-use change on Prairie Pothole we
The Influence of Stream Flow Patterns on Juvenile Salmon Growth in Southeast Alaska
In the Gulf of Alaska, streams will experience more dramatic low water events, interspersed with larger and potentially more frequent high flow events in the coming decades. Reduced stream flows are likely to occur due to diminished snowpack and seasonal droughts, while higher flow events are likely to occur with more frequent storms and rain-on-snow events. These changes are likely to influence t
Understanding and Forecasting Potential Recruitment of Lake Michigan Fishes
Yellow perch and alewife are ecologically, economically, and culturally important fish species in Lake Michigan whose populations support recreational and commercial fisheries. However, both of these species’ populations have been in decline for over 20 years. This project seeks to understand the factors affecting variability in offspring survival of yellow perch and alewife in Lake Michigan in o
Understanding Brook Trout Persistence in Warming Streams
Cold-water adapted Brook Trout were historically widely distributed – ranging from northern Quebec to Georgia, and from the Atlantic Ocean to Manitoba in the north, and along the Appalachian ridge in the south. However, studies show that due to factors associated with climate change, such as increased stream temperature and changing water flow, the number of streams containing Brook Trout is decli
Understanding Impacts on Southeastern Grasslands from Climate Change, Urban Expansion, and Invasive Species
Much of the biodiversity of the southeastern U.S. is found in grasslands, including meadows, prairies, glades, and savannas. These grasslands provide vital habitat to a variety of plants and animals, but many grassland types have undergone over 90% loss due to fire suppression and urban sprawl. The remaining grassland patches—remnants—now face emerging threats from invasive species and climate cha
Vulnerability of Lower-Elevation Aspen Forests to Altered Fire and Climate Dynamics: Assessing Risks and Developing Actionable Science
Aspen forests are considered keystone ecosystems, meaning that loss of aspen habitat would result in negative impacts to numerous plant and animal species. Aspen also provide important economic and social benefits, including drawing tourists, serving as potential fire breaks, improving local economies, and providing forage for wildlife and livestock. Ecologically-valuable aspen forests are conside
An Alert System for Managing At-Risk Species in Cascadia under Climate Change
A rapidly changing climate and expanding human footprint is driving increased rates of landscape change in the Pacific Northwest. This makes it challenging for managers to know if and to what extent recovery goals and conservation plans for at-risk species need to be modified to account for changing habitat conditions. Addressing this challenge requires accurate, up-to-date information about lands
Analysis and Visualization of Climate Information to Support USFWS Species Status Assessments
Under the Endangered Species Act, the U.S. Fish and Wildlife Service (USFWS) must evaluate the status of at-risk plants and animals in the U.S. A Species Status Assessment (SSA) is a scientific assessment prepared for each at-risk species to help inform a range of management decisions under the Endangered Species Act. SSA’s are currently needed for more than 350 species, 250 of which are in the So
