The Colorado River provides water to 40 million people in the southwestern United States. Consistent water level declines in Colorado River Basin reservoirs have focused research attention on the long-term changes in winter precipitation and the timing of snowmelt and runoff. Research on how warming temperatures affect winter precipitation and spring snowmelt is ongoing, however, less...

High elevation red spruce forests are among the most iconic and visited natural communities in the High Alleghenies of the Central Appalachian Mountains. These ecosystems provide many services such as clean water and carbon sequestration, as well as habitat for species of high conservation concern, i.e., the eastern brook trout, the northern goshawk, and the northern flying squirrel...

Project Overview Climate change threatens keystone plant communities and insects that make up the base of functional food webs, but restoration practitioners struggle to factor climate considerations into restoration projects for a number of practical reasons. Researchers supported by this National CASC project will create a trait-based plant vulnerability assessment to guide restoration

Black ash wetlands occupy over 1.2 million hectares of forest in the Great Lakes region, providing habitat for unique and diverse wildlife communities. In these wetlands, black ash trees are a foundational species, regulating all aspects of ecosystem function, and are also an important cultural resource for Native Americans, specifically for basket-makers. Black ash wetlands are...

Wildfire is a natural and essential process in forest ecosystems, but characteristics of fire regimes that have shaped these landscapes over long time scales are changing with climate change and human activities. In some places, changes in fire size, frequency, and severity threaten to degrade essential ecosystem services that produce clean air and water, fertile soil for crop and wood...

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...

Society makes substantial investments in federal, Tribal, state, and private programs to supplement populations of valued species such as stocking fish, planting trees, rebuilding oyster reefs, and restoring prairies. These important efforts require long-term commitment, but climate change is making environmental conditions less predictable and more challenging to navigate. Selection of...

As climate change looms large, the Aaniiihnen and Nakoda people of the Fort Belknap Indian Community are undertaking a climate change impact assessment in the Little Rocky Mountains to better prepare for the future. This mountain range is home to numerous food and medicinal species of cultural importance. It is critical to understand how climate change has affected and will affect...

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...

Across the western U.S., pinyon and juniper trees are expanding into sagebrush and grassland plant communities. This vegetation change has been perceived to have a significant impact on the economic value of these grasslands, which support activities such as livestock grazing and hunting, but expanding pinyon and juniper forests may also lead to increased risk of fire. Over the past...

Berry-producing plants, a key resource in Alaska Native communities, provide primary subsistence and have been integral to maintaining cultural cohesion, sense of place, and physical ties to the surrounding landscape. Despite the importance of berry-producing plants, relatively little is known about their vulnerability to changes in climate and environmental conditions. The dynamics of...

In ecosystems of the southwestern US intensifying wildfires and climatic shifts are causing widespread tree mortality and slowed recovery after fires. Ecological refugia are areas that retain intact biological features or ecological processes after disturbance. These refugia are essential for the survival of a wide array of species and communities and aid in ecosystem recovery by...
