Forecasts of Climate-Associated Shifts in Tree Species (ForeCASTS)

ForeCASTS.pngForest ecosystems are ever adjusting to changing conditions resulting from seasonal fluctuations in temperature and precipitation, disturbances like storms and wildfire, and interactions among species, but changing climatic conditions could pose a severe threat to forest trees. Whether tree populations adapt on site to changing habitat conditions, shift their ranges to new suitable locations, or simply die out in response to climate change, the forests we know today—and the genetic makeup of the tree species within them—could be very different by the middle of the 21st century.

With support from the USDA Forest Service Forest Health Monitoring program, Eastern Threat Center scientists are developing maps that pinpoint locations where climate change pressures are likely to be most intense to help scientists, land managers, and policy makers target tree species for monitoring, conservation, and management activities. The maps, known as Forecasts of Climate-Associated Shifts in Tree Species (ForeCASTS), depict future suitable habitat ranges for North American tree species within the United States as well as across the globe. Using projections of future climate in combination with the concept of fine-scale ecoregions—land areas that share similar environmental characteristics, such as soils, topography, and climate variables—ForeCASTS can ultimately be used to assess the risk to genetic integrity of North American forest tree populations.
