Northwest

Climate change is contributing to an increase in wildfire activity in the western United States, including the Blue Mountains and Eastern Cascades Slopes and Foothills of the Inland Northwest. Some forest ecosystems are changing from forest to non-forest because of severe fires, a hot and dry climate, and/or the absence of a viable seed source. On sites impacted by wildfire, managers are tasked wi

A persistent management question is whether current climate adaptation planning will remain robust when facing a growing number of invasive species. The concern is that current management strategies that focus exclusively on single invasive species and overlook climate-driven biological interactions, may lead to poor decisions. By delivering actionable science, this project directly informs specif

Climate change has the potential to magnify existing problems in conservation, such as invasive species and disease. This threat is particularly severe in the Klamath Basin, where the fish parasite Ceratonova shastais making national headlines for killing salmon, and invasive trout have extirpated populations of native trout. The Klamath Basin is slated for one of the largest restoration projects

Sagebrush steppe ecosystems provide livelihoods for humans and essential habitats for wildlife, and thus management actions in these systems to promote wildlife persistence must strike a balance between human needs with those of wildlife. Across the western U.S., these landscapes have been heavily altered or lost through human activities, and climate change is expected to cause further changes in

A change in wildfire regimes and the expansion of invasive grasses are degrading sagebrush ecosystems, altering wildlife habitats, and threatening property and human livelihoods. In response, land managers often treat large areas of land with fuel reduction or post-fire seeding treatments in an attempt to reduce these risks. However, the trajectories of ecosystem change following treatment are inc

Natural & cultural resource managers are facing a slew of new challenges for managing public lands stemming from climate change and human-driven stressors like invasive species, fragmentation, and new resource uses. In some cases, the very landscapes and species they are managing are changing in significant ways, transforming from one set of conditions to another. As a result, previously successfu

The Pacific Northwest is a hotspot for temperate amphibian biodiversity and is home to many species of salamanders and frogs found nowhere else on earth. Changing climatic conditions threaten habitat for many of these species and may also enhance the risk of disease and invasive species encroachment. State and federal wildlife agencies are in the process of evaluating these threats, but informatio

Mountain meadows in the western United States provide key habitats for many plant and wildlife species, many of which rely exclusively on these areas. Mountain meadows are also treasured by the public and provide beautiful areas to view wildflowers and wildlife on public lands such as national parks. However, mountain ecosystems are expected to be disproportionately affected by climate change. The

Surface-water availability has been identified as one of the biggest issues facing society in the 21st century. Where and when water is on the landscape can have profound impacts on the economy, wildlife behavior, recreational use, industrial practices, energy development, and many other aspects of life, society, and the environment. Projections indicate that surface-water availability will be gen

As droughts become more frequent, there is a growing need to understand how drought impacts streamflow permanence. Intermittent streams, or streams that go dry at some point during the year, are found in all ecoregions and represent over half of the global stream network length. As stream intermittence increases, there will be implications for both aquatic and terrestrial wildlife communities, lan

Native mussels are in precipitous decline across North America. As part of the Confederated Tribes of the Umatilla Indian Reservation’s (CTUIR) First Foods management framework that places significant value on the cultural importance of traditional food resources, they have been identified as a top conservation priority in the Pacific Northwest. Freshwater mussels are a vital component of river ec...

Throughout the Pacific Northwest, invasive flora threatens river ecosystems and the communities that depend on them. Invasive plants harm water quality, occupy habitat for native species, reduce recreation opportunities, and damage infrastructure such as pumps and dams. Resource managers from federal, state, and local agencies, as well as local non-profits, spend hundreds of thousands of dollars o
