FWS Reopens Comment Period for Polar Bears ESA Listing
The US Fish and Wildlife Service has published nine new research reports providing "current data and modeling reports relevant to the final determination of whether the polar bear...qualifies for listing under the endangered species act of 1973, as amended."
Comments on the new documents are due to FWS by October 5, 2007.
The nine reports were prepared by the U.S. Geological Survey. They are:
