Fire suppression over the past century has caused widespread changes to the structure and function of coniferous forests in the western U.S. Forest restoration efforts to reverse these changes must ensure that restoration prescriptions will not adversely impact federally listed species. Northern Idaho Ground Squirrels are federally threatened and have a very small range in central Idaho. We are comparing the effects of 2 forest treatments on Northern Idaho Ground Squirrels : 1) mechanical thinning followed by a fall-season burn (past prescription used by USFS); and 2) no treatment (control). We are using a Before-After-Control-Impact (BACI) design with field sampling >5 years prior to treatment and for >4 years post-treatment. The project is a collaboration between USGS Idaho Cooperative Fish & Wildlife Research Unit, U.S. Forest Service, U.S. Fish and Wildlife Service, and Idaho Department of Fish and Game. The results will help determine whether thinning and fire treatments can be used to improve habitat suitability for Northern Idaho Ground Squirrels.
