The USGS Public Events Calendar—Start with science all year long.

The scientific research performed by the USGS in the Detroit River International Wildlife Refuge is essential to understanding ecosystem processes, setting priorities, and selecting restoration and conservation actions within an adaptive management context."
John H. HartigEcosystems, such as the wetlands of the Greater Everglades, the Mojave and Sonoran deserts, the Chesapeake Bay estuaries and the Great Lakes, support life through the ecosystem services they provide, including clean water, hazard protection, food and fiber, and resilience to disease and invasive species. But the value of the ecosystem services provided by these vast natural areas is declining because of multiple threats such as adverse land-use changes, invasive species, contaminants, and water scarcity. USGS ecosystem restoration projects aim to restore the health of ecosystems, which in turn will restore their social, ecological, and economic benefits. From the alpine tundra to the coral reefs of Florida and Hawaii, USGS ecosystem science is providing the critical research needed to understand and reverse these declines.
Landsat satellite imagery collected between 2002 and 2008 was used to develop a cloud-free mosaic view of the Great Lakes. Fluctuating water levels in the Great Lakes are the focus of current wetland research efforts.
