Forests

Climate change is causing an increase in the amount of forested area burned by wildfires. When coupled with more intense droughts, these dry post-fire conditions may limit tree regeneration in some areas, potentially causing a shift to non-forest vegetation. Explore our science on forests below to learn about how CASC scientists are working to conserve our forests.

Forest Management Tools to Maximize Snow Retention under Climate Change

Climate change is projected to cause earlier and less snowmelt, potentially reducing water availability for terrestrial and aquatic ecosystems and for municipal and agricultural water supplies. However, if forested landscapes can be managed to retain snow longer, some of these environmental and financial impacts may be mitigated. Results from our research team demonstrate that in the Pacific North

Forests of the Future: Integrated Assessment of Climate Change and Ecosystem Diversity

Recent estimates of the magnitude of species’ range shifts, extinctions, and changes in ecosystem processes resulting from climatic change are alarming. Estimates of extinction rates and population losses attributable to climatic change are often based on studies of modeled biogeographic distributions, which rely on simple relationships between present-day distributions of species and climate vari

Foundational Science Area: Assessing Climate Change Impacts to Wildlife and Habitats in the North Central U.S.

In the North Central U.S., temperatures are rising and precipitation patterns are changing, with consequences ranging from more frequent and severe wildfires to prolonged drought to widespread forest pest outbreaks. As a result, land managers are becoming increasingly concerned about how climate change is affecting natural resources and the essential services they provide communities. The rates

How Does Drought Influence Fire Severity in the Southwestern U.S.?

There is a growing realization that current warming trends may be associated with increases in the size, frequency, and severity of forest fires in the West. While rising temperatures can create drought conditions that favor severe fires, it is also possible that drought limits the ability of trees to survive a fire. During a drought, there is less water available for trees and more outbreaks of h

Measurement of El Niño Southern Oscillation (ENSO)-related Climate Conditions and Ecosystem Responses in Hawaiʻi

As elevation increases, both temperature and moisture availability decrease. In many parts of the world, this decrease in temperature is a limiting factor for vegetation—at certain elevations, the temperature becomes too cold for plants to survive. However in the tropics, moisture availability may play a more important role than temperature in determining the altitude at which forests can grow. Fo

Moving from Awareness to Action: Informing Climate Change Vulnerability Assessments and Adaptation Planning for Idaho and Montana National Forests

The rugged landscapes of northern Idaho and western Montana support biodiverse ecosystems, and provide a variety of natural resources and services for human communities. However, the benefits provided by these ecosystems may be at risk as changing climate magnifies existing stressors and allows new stressors to emerge. Preparation for and response to these potential changes can be most effectively

Nome Creek Boreal, Fire and Permafrost Hydrology investigations

The Nome Creek Experimental Watershed (NCEW) has been the site of multiple studies focused on understanding hydrology, biogeochemistry, and ecosystem changes related to permafrost thaw and fire in the boreal forest. The boreal forest is the Earth’s largest terrestrial biome, and thus plays a major role in biogeochemical cycling, creation of habitat for wildlife, as well as wilderness and resources

Projecting the Effects of Climate Change on Aspen in the Central and Northern Rocky Mountains

Aspen is an environmentally, economically, and socially important species in the western U.S. It is typically the most abundant deciduous tree species in mountainous landscapes of the western U.S., providing food and habitat for a variety of wildlife, including black bear, deer, elk, moose, and numerous bird species. Aspen woodlands also provide high quality forage for livestock and draw tourists

Projecting the Future Distribution and Flow of Water in Alaskan Coastal Forest Watersheds

Water is a key ecosystem service that provides life to vegetation, animals, and human communities. The distribution and flow of water on a landscape influences many ecological functions, such as the distribution and health of vegetation and soil development and function. However, the future of many important water resources remains uncertain. Reduced snowfall and snowpack, earlier spring runoff, i
