Changes in Forested Landscapes of the Northeastern U.S. Under Future Climate Scenarios
Forests in the eastern United States are changing in response to ecological succession, tree harvest, and other disturbances and climate change has the potential to further change these forests. We predicted the distribution and abundance of common tree species across portions of the eastern U.S. under alternative climate scenarios that varied in the amount of warming by the end of the century from 1.1 to 4.2 degrees celsius. We used a forest landscape change model to forecast changes in tree abundances and distribution in the North Atlantic region of the U.S. while accounting for climate change, succession, and harvest. We then considered a broader region of the U.S. and combined our results with results from previous...

Integrating ecological forecasting methods to improve applications for natural resource management: An invasive species example
Projecting the effects of climate change on plant and animal species distributions and abundance is critical to successful long‐term conservation and restoration efforts. There have been significant recent advances made in the areas of: (1) climate forecasts; (2) habitat niche modeling; (3) mechanistic modeling; and (4) observation techniques and networks. However, projections of biological change are fundamentally limited by a lack of integration and inter‐comparison between these various forecasting approaches. The proposed working group will focus on integrating ecological forecasting methods for two well studied invasive species: cheatgrass (Bromus tectorum) and gypsy moth (Lymantria dispar). Our goal is to...
ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
