The USGS Ecosystems Mission Area provides science to help America achieve sustainable management and conservation of biological and ecological resources in wild and urban spaces. Our scientists examine consequences of climate and environmental change; effects of management actions on communities, lands, and species; and risks and solutions to harmful invasive species, wildlife diseases, and contaminants in the environment. This geonarrative highlights our research addressing these issues and illustrates how science is essential for resource management decisions that protect and conserve lands and waters enjoyed by communities across the U.S.
