Landscapes
From boreal forests to coral reefs, the United States is home to a plethora of diverse ecosystems, each of which faces different challenges under climate change. CASC-supported scientists are examining how landscapes throughout the U.S. are being affected by changing temperature and precipitation patterns and how managers can best facilitate climate adaptation.

A Climate-Informed Adaptation and Post-Fire Strategy for the Southwestern Region
The Southwest is projected to face significant climate challenges in coming decades; and many of these stresses have already begun. In recent years, multiple climate assessments have been developed for the Southwest that corroborate forecasts of remarkable change to vegetation pattern and the vulnerability of regional ecosystems and suggest that measurable change is already ongoing. Disturbance ev
A Climate-Informed Conservation Strategy for Southern California’s Montane Forests
California is a world biodiversity hotspot, and also home to hundreds of sensitive, threatened, and endangered species. One of the most vulnerable ecosystems in California is the “sky island” montane forests of southern California, forests of conifers and hardwoods located only in high-elevation mountain regions. Montane forests serve many important ecosystem functions, including protecting the up
Can Climate Change Mitigation Through Forest Management Save the Moose in Minnesota?
Moose are an economically and culturally important species in Minnesota. Like many species, however, moose are experiencing reductions in distribution and abundance across the Midwest as a result of climate change and habitat loss. Moose populations have declined by 60% since 2006, in part because of thermal heat stress in warming summers and increased frequency of contact with white-tailed deer t
Can Management Actions Support Forest Regeneration Across the Diverse Landscapes and Climate Change Futures of the Southwestern U.S.?
Ponderosa pine forests are declining and their future persistence is uncertain. Most research on forest declines has focused on the effects of disturbances including wildfire, insect outbreaks, and severe drought on mortality of mature trees. Yet, recent research suggests that ponderosa pine declines may be even more severe as these ecosystems fail to regenerate naturally (i.e. grow from seed to a
Determining Successful Management and Restoration Strategies for Pinyon-Juniper Communities in the Face of Changing Climate and Wildfire
Pinyon-juniper woodlands are important ecosystems in the western U.S. that provide numerous critical environmental, economic, and cultural benefits. For example, pinyon pines are a significant cultural resource for multiple Native American Tribes and provide necessary habitat for plants and wildlife (including at risk species, such as the pinyon-jay). Despite their importance, stress put on pinyon
Drought and Disturbances as Drivers of Long-Term Ecological Transformation and Risk
Forested areas in the Western U.S. that are impacted by disturbances such as fire and drought have increased in recent decades. This trend is likely to continue, with the increase in frequency and extent of wildfire activity being especially concerning. Resource managers need reliable scientific information to better understand wildfire occurrence, which can vary substantially across landscapes an
Exploring Large Downed Wood as Post-Fire Refugia for Terrestrial Salamanders in Pacific Northwest Forests
Downed wood on the forest floor does more than provide habitat for amphibians, reptiles, birds and mammals. These decomposing habitat structures modify the temperature and moisture conditions in the forest itself. Inside and around downed wood, local climate conditions, or microclimates, provide wildlife with stable habitats that allow for persistence during and after wildfires. Cooler, wetter mic
Exploring the Potential for Adaptive Tree Plantings to Restore and Sustain Forest Habitats Across the Upper Lake States
Forests across the U.S. are experiencing unprecedented tree mortality caused by a variety of stressors, including invasive insects, disease, extreme weather, wildfires, and droughts. For example, the emerald ash borer, a nonnative insect, has killed tens of millions of trees in the Lake States region of Minnesota, Wisconsin, and Michigan alone in the past decade. Tree die offs alter the structure
Harnessing the Hydraulic Traits of Trees to Adapt Forest Management in the Pacific Northwest
Climate change impacts on forests, including drought and wildfire, are of increasing concern to managers, conservationists, researchers, and culture bearers in the Pacific Northwest. Warmer temperatures exacerbate forest stress by accelerating evaporation and drying-out of the land surface and vegetation. These hotter drought conditions have been implicated in recent tree mortality events regional
Promoting Climate Resilience and Soil Health in Northern Rockies Grasslands Through Bison and Cattle Grazing Management: Weaving Together Indigenous and Western Science
Native American tribes are interested in managing their homelands for future generations, using both Indigenous and western science to make decisions in culturally appropriate ways. In particular, there is interest in strategic grazing management as a natural climate solution to strengthen the resilience of grasslands to a changing climate. This includes the restoration of free-ranging bison as we
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
