We appreciate all the interest in the USGS research on Polar bears. Information can be obtained from the web information below.

USGS Changing Arctic Ecosystems Initiative

In 2007, the U.S. Geological Survey (USGS) was asked by the Secretary of the Interior to conduct a series of analyses to help reduce uncertainty in the Endangered Species Act (ESA) listing decision for the polar bear.  The USGS produced a series of reports, including projections of the future population trends of polar bears.  These projections were supported by a strong foundation in empirical data from long-term USGS studies.  The Department of the Interior saw a need to conduct similar analyses for other species in the Arctic, thus beginning the USGS Changing Arctic Ecosystems Initiative.

Decisions Informed by the USGS Changing Arctic Ecosystems Initiative

Through the Changing Arctic Ecosystems (CAE) Initiative, the U.S. Geological Survey (USGS) is informing key resource management decisions by better understanding how wildlife populations of special interest to the Department of the Interior (DOI) are responding to rapid physical changes in the Arctic. Below are some examples of how CAE research is informing decision-making.
