Project Overview Prairie dog colonies in North America’s Central Grasslands undergo cycles of collapse and recovery caused by the non-native sylvatic plague, and each phase of the cycle negatively affects wildlife or livestock. Researchers supported by this North Central-CASC project will develop a decision-support web tool for users to predict prairie dog colony dynamics under changing climatic conditions to help optimize management strategies of wildlife and cattle. Project Summary Prairie dogs are crucial to North America’s Central Grasslands, creating habitat for other wildlife by digging burrows and clipping vegetation, and serving as a key food source for many predators. However, the sylvatic plague, a non-native...

Grasslands in the Great Plains are of ecological, economic, and cultural importance in the United States. In response to a need to understand how climate change and variability will impact grassland ecosystems and their management in the 21st century, the U.S. Geological Survey North Central Climate Adaptation Science Center led a synthesis of peer-reviewed climate and ecology literature relevant to grassland management in the North Central Region (including Montana, Wyoming, Colorado, North Dakota, South Dakota, Nebraska, and Kansas). This synthesis was done to begin to address grassland managers’ information needs and identify research gaps. This open-file report summarizes the impacts of climate change and variability...
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.
