The U.S. Forest Service Northern Region has conducted bat surveys each year during 2005-2007 to gather information on the distribution and status of bats on Forest Service lands in Montana. During 2005, 57 sites were surveyed on selected National Forest (NF) Ranger Districts (RD); the 2005 field season provided information for areas previously without documented bat activity and resulted in numerous new county records for several species. In 2006, with an increased number of surveyors, 75 new sites were surveyed using both mist-net and acoustic sampling methods. A pilot project was undertaken following the 2006 field season to investigate bat detection probabilities for surveys using more than one detection method (mistnetting and acoustic sampling). During the 2007 field season, 87 new sites were surveyed: 59 acoustically, 28 mist-netted. Areas targeted for survey included RDs and/or backcountry areas of select RDs lacking any survey coverage. These included the Dillon, Jefferson, Madison, Pintler, Wisdom, and Wise River RDs of the Beaverhead-Deerlodge NF; the Ashland and Beartooth RDs of the Custer NF; Glacier View, Hungry Horse, Spotted Bear, Swan Lake, and Tally Lake RDs of the Flathead NF; the Gardiner RD of the Gallatin NF; the Rocky Mountain RD of the Lewis and Clark NF; and the Seeley Lake and Superior RDs of the Lolo NF. Ten species of bats, represented by 218 individuals, were captured by mist-net during mid June-late August 2007. Species captured included Little Brown Myotis (Myotis lucifugus), Western Long-eared Myotis (M. evotis), Long-legged Myotis (M. volans), California Myotis (M californicus), Big Brown Bat (Eptesicus fuscus), Hoary Bat (Lasiurus cinereus), Silver-haired Bat (Lasionycteris noctivagans), Townsend's Big-eared Bat (Corynorhinus townsendii), Eastern Red Bat (Lasiurus borealis), and Pallid Bat (Antrozous pallidus); the latter two are the first of their respective species to be detected by any method during the first three years of the
