Missoula, MT -

A conservation group is suing the U.S. Geological Survey for information on threatened grizzly bears in northwestern Montana.

The Alliance for the Wild Rockies says the USGS failed to respond to a Freedom of Information Act request for reports and findings on the Cabinet-Yaak Grizzly Bear DNA Project.

KECI-TV reported Monday the project aims to give researchers a better idea of the number of bears in that area through DNA from hair samples.

The group's lawsuit says it has not received a response to its request after 2 1/2 months. Government agencies have 20 working days to make an initial response to an information request.
