In order to aid the Caribou National Forest in its efforts to prepare for the closure of abandoned mines in the near future and simultaneously to manage Category 2 (C2) bat species, abandoned mines in the Bear River Range of Idaho were surveyed and evaluated in terms of their potential as bat roosts during the warm season. All of the eight adits surveyed are used by bats. Seven of the eight are used as night roosts; two of these seven adits are used as day roosts. It is known from previous winter visits that two of the eight adits are used as hibemacula. Four of the adits have yet to be surveyed in winter. This summer survey reinforces the widely held concept that abandoned mines in the West have become important roost sites for the Townsend's big-eared bat; in many western states, abandoned mines are known to make up the majority of the remaining roosts for this species. Seven of the adits should be considered significant night roosts for the Townsend's big-eared bat, due to the numerous moth wings found within them.
