Ecosystems

The USGS Ecosystems Mission Area provides science to help America achieve sustainable management and conservation of biological resources in wild and urban spaces, and places in between. Ecosystems 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.
