Forests

Atmospheric nitrogen deposition, climate change and recreation are rapidly altering high elevation ecosystems. This project will evaluate long-term biogeochemical, hydrological, and ecological trends in Rocky Mountain National Park to understand the causes and rates of change in alpine and subalpine waters, soils, and vegetation. Policy makers and resource managers of high-elevation, protected...

Climate change, invasive species, and diseases are threatening Northeastern forests, with consequences for bird populations and carbon storage. Researchers supported by this Northeast CASC project will evaluate whether already-implemented climate adaptation strategies in the region have been effective at protecting bird habitat and what the implications of carbon storage have been. The analyses wi

The Hemlock Woolly Adelgid (HWA) is an insect causing extensive hemlock tree die-offs in the northeast, and a lack of information on climate adaptation practices is hindering effective forest management. With the overall goal of fostering resilient forests that support northeastern hemlock ecosystems and wildlife, researchers supported by this Northeast-CASC project will work with land managers to

Recent catastrophic droughts and wildfires have killed almost 20% of mature giant sequoia trees across California, and it is uncertain whether natural seedling regeneration will be enough to restore these forests, especially in severely burned areas. Researchers supported by this Southwest CASC project will assess whether soil conditions, such as moisture and soil microbial communities can increas

Much of the cranberry bog farmland in Massachusetts used to be Atlantic white cedar ecosystems, which provide important habitat, water filtration, and cooling effects on the landscape. Researchers supported by this Northeast CASC project will experiment with modern restoration strategies and integrate Indigenous cultural stewardship practices to build and sustain climate-resilient Atlantic white c

Urban forest managers often lack the essential information needed to make strategic decisions about planting and maintaining trees to mitigate climate change effects in urban areas. In this project, Southeast CASC-funded researchers will provide data on the health of urban tree species in the region and conduct an ecological and economic cost-benefit analysis to help local and regional urban fores

Project Overview Guam’s forests are vital to the ecosystem and local communities, but they face threats from wildfires, water quality, and invasive species, among others. To restore these ecosystems, researchers supported by this Pacific Islands CASC project will research the roles of native plants by identifying their “functional traits,” and using that knowledge to select species for restoratio

The southeastern U.S. is home to many rare plant species, some at risk of extinction. A new national list has identified the top plant “Species of Greatest Conservation Need” (SGCN) across the region which can help southeastern states update their State Wildlife Action Plans (SWAPs) to include plants for the first time. In partnership with the Southeast Plant Conservation Alliance, NatureServe, a

In Hawaiʻi, a large percentage of historically forested areas have been lost, driven in part by changes in land use, such as the conversion of forests into pastures for livestock. This transformation has not only resulted in widespread loss of native biodiversity and important ecosystem functions but has also increased the risk of fire on the landscape. Though targeted restoration efforts have the

Controlling the spread and impacts of invasive species is becoming more challenging as climate conditions change. More relevant information is needed to guide timely and localized management actions for these species to preserve cultural resources and ecosystem integrity. Data products are most valuable when they are developed with input from the people who use them for invasive species managemen

Ecosystems respond to disturbances (such as wildfire) and changing climate in a variety of ways, including persistence, recovery, and reorganization into new combinations. Some species respond by migrating across the landscape over time, which allows them to keep up with changing climate. Many forests recover after wildfire by regenerating from seeds, and public land managers often assist these pr

Large, hot, fast-moving wildfires are an increasing threat to communities and to the watersheds they rely upon. Forest managers work to reduce the risk from these fires using forest thinning and prescribed burning to reduce the amount of fuel in the forest. However, these activities are expensive, and it can be challenging to identify which acres of forest should be targeted with thinning and burn
