Abstract:

This report details the results of field assessment of bat populations in the Idaho Panhandle National Forests. Because the completion of a final report was delayed as a result of several failures of the Idaho State University dermestid colony needed to prepare skulls, a museum assessment of bats in collections of 32 U.S. museums and data found in original literature were added to provide an expanded database during the preparation of the final report. A summary review of important category 2 species (proposed for listing as Endangered or Threatened under the Endangered Species Act but awaiting further biological research and field study) is provided in the discussion. A complete summary of the federal and Idaho agency status of each species is available (CDC, 1994). Preliminary assessment of the area to be surveyed was completed during July 22 to August 3, 1988, by Keller following receipt of 16 surveys (included in this report) mailed to district managers and knowledgeable individuals in the area to determine sites where bats had been observed. The intensive field work was conducted from July 12 to August 20, 1989, by Doering. Late fall assessment of a selected number of mines and one large tunnel system was completed during early November 1989 by Keller with Dwain Lowery (Conservation Officer, Idaho Department of Fish and Game), who helped locate several closed mine sites. Text and identifications were completed by Keller. No sonographic analyses were completed, but sonic activity of bat populations was monitored to select sampling sites. Additional information was added to the report as a result of new studies completed adjacent to the forest in 1994.
