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 generally reduced in the future because of multiple factors including climate change, increased drought frequency and severity, and altered water and land use. Thus, it is important resource managers understand which areas are most vulnerable to reduced water availability impacts, and to what extent current conditions may...

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 with maintaining timber value, wildlife, recreation, and cultural resources important to society. However, managers contend with multiple constraints in forest restoration. To address these constraints, a network of scientists and managers of the Blue Mountains and Eastern Cascades will co-develop a decision support platform...

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 specific planning, management and decision needs of tribal and governmental partners working in the Columbia River Basin. First, we assess the information needs for, and barriers to, effective aquatic invasive species management in the face of climate change in the Columbia River Basin. This helps synthesize knowledge and build...

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 inconsistent across the sagebrush steppe. In some places, treatments are successful, leading to a decrease in invasive grasses which allows native plants to recover. In other places, treatments either have no effect or they facilitate the spread of invasive grasses. Under some climate conditions, native grasses and forbs do...

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 successful management strategies may become less effective, or in some cases ineffective. New and transforming conditions leave managers in a bind on how to respond to transforming public lands and natural resources. On the most basic level managers have three choices of how to respond: resist change, accept change, or direct change...

Throughout the Pacific Northwest, invasive flora threaten 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 on monitoring and exterminating invasive plants. Management costs and damages are likely to rise as climate change warms temperatures and reduces rainfall across the basin, expanding potential habitat for invasive plants and affecting the effectiveness of management. For some time, scientists have recognized the potential...

As wildfire activity surges in the western U.S., managers are increasingly challenged by decisions surrounding managing post-fire environments.Changing fire regimes and warmer,drier post-fire conditions are increasing the likelihood of post-fire vegetation transitions, for example,from forest to grassland. Given the economic and ecological importance of these ecosystems, transformation is a concern for managers, policy-makers, and the public. As rapid environmental changes occur, management aimed at maintaining historical conditions will become increasingly untenable, requiring managers to make decisions that steward vegetation toward desired or novel conditions. The Resist-Accept-Direct (RAD) framework provides...

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 the quality and connections between habitat patches that could exacerbate declining populations of vulnerable wildlife species. To better manage these ecosystems under shifting conditions, researchers are examining how species use the mosaic of agricultural and intact sagebrush landscapes and how agricultural practices...

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 information is lacking. Wildlife managers need to know: the availability of suitable habitat under different climate scenarios; the vulnerability of at-risk amphibians to different diseases, and how climate change will affect that vulnerability; and the potential future spread of harmful invasive species like American bullfrogs,...

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 ecosystems, a historic food resource, and were used for adornment, jewelry, tools, and trade. Yet, little is known about the basic biology and ecology of these organisms, including where they are, how many of them remain, and what habitat characteristics (e.g., water temperature, flow, etc.) are important to them. There is...
