This book was released on 1993 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eight species of bats were documented on the Townsend Ranger District during five nights of mist-netting during the summer of 1992. Two of these species, the Townsend's Big-eared bat, and the Fringed myotis are on the Montana Natural Heritage Program's sensitive species list. The Townsend's big-eared bat is also listed by the U.S. Forest Service Northern Region as a sensitive species. Females of the Townsend's big-eared bat, the Small-footed myotis, and the Long-legged myotis suggest that maternity colonies probably exist in the vicinity. The species diversity and the presence of rare and sensitive bat species indicates that portions of the Townsend Ranger District of the Helena National Forest are excellent habitat for bats. Management activities to maintain this habitat will need to protect and preserve caves, ensure that old mine adits are un-occupied in summer, autumn, and winter before blocking entrances, maintain water sources, and maintain a diversity of habitats that include, where applicable, mature hardwoods, older stands of Douglas fir, and healthy riparian areas.

Download or read book Bat Surveys on USFS Northern Region Land in Montana written by Paul Hendricks and published by . This book was released on 2005 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The distribution and status of bats in Montana remain poorly documented on US Forest Service Northern Region lands. This is of conservation interest because management activities on Forest Service lands (e.g., timber harvest, mine closures, closures of historic buildings) may have unintended consequences on habitats bats use for roosting and foraging and may therefore negatively impact bat populations. Additionally, the Northern Region has designated Townsend's Big-eared Bat (Corynorhinus townsendii) a Species of Concern requiring special attention; it is widespread but infrequently captured in Montana, with few documented hibernacula and maternity roosts and a reputation for being highly susceptible to human disturbance at roost sites. The Northern Region recognized the need for additional documentation of bats on Forest Service lands to address inventory and monitoring requirements, and initiated bat surveys in 2005 across the Region on selected National Forest (NF) Ranger Districts (RD). In Montana, these included Swan Lake RD-Flathead NF, Bozeman RD-Gallatin NF, Townsend RD-Helena NF, Libby RD-Kootenai NF, and Judith RD-Lewis & Clark NF. Following a modified protocol based on the Oregon Bat Grid system, crews surveyed non-randomly chosen suitable habitats within randomly chosen 10 x 10 km2 sample units in each RD; ten sites (often two/sample unit) on each District were sampled, for a total of 50 sites surveyed on Northern Region lands in Montana. Thus, this approach is primarily targeted at identifying species richness within grid cells; inferences on rates of occupancy are limited to the percent of 10 x 10 km2 grid cells where a species was detected within each sampled RD. Eleven species of bats, represented by 795 total individuals, were captured during late-June to mid-August 2005. Species captured included Townsend's Big-eared Bat at two sites, Big Brown Bat (Eptesicus fuscus) at 14 sites, Hoary Bat (Lasiurus cinereus) at 20 sites, Silver-haired Bat (Lasionycteris noctivagans) at 25 sites, California Myotis (Myotis californicus) at nine sites, Western Small-footed Myotis (M. ciliolabrum) at eight sites, Western Long-eared Myotis (M. evotis) at 26 sites, Little Brown Myotis (M. lucifugus) at 32 sites, Fringed Myotis (M. thysanodes) at four sites, Long-legged Myotis (M. volans) at 23 sites, and Yuma Myotis (M. yumanensis) at two sites. No bats were captured at five of the sites sampled, although presence of bats was noted at each. The 2005 field survey filled important gaps in documented distributions in Montana, adding several new county records and underscoring the need for additional survey effort to define bat distributions on USFS landscapes more fully. A summary of all existing bat records across the region clearly shows large distribution gaps for all species, further underscoring the need for addition surveys. In particular, large portions of the Beaverhead-Deerlodge NF, Custer NF, Flathead NF, Gallatin NF, and Lewis and Clark NF lack records for any bat species. We recommend that the USFS Northern Region continue with a grid-based random sampling scheme stratified by ecoregion or Ranger District, resulting in a site-occupancy approach that allows for valid inference of presence across the selected stratum. A grid-based sampling scheme is an important monitoring approach that should be extended beyond USFS lands and coordinated with other partner agencies and organizations to guide effective bat management across the state.

Book excerpt: This report documents the findings of field investigations into the relative abundance and distribution of bats on the Kootenai National Forest and parts of the Lolo National Forest of western Montana from May 15 to September 28, 1993. Two primary methods of investigating species composition and abundance were used. Bat echolocation calls were monitored along selected transect routes beginning at sunset to record the relative abundance and activity patterns of bats. Mist nets were deployed across creeks, roads, trails, and adits to capture bats, providing the most reliable means for documenting species presence, and providing information on age, sex, and reproductive status. A total of 123 bats representing eight species were captured in the study area. Bats of the genus Myotis accounted for 91 percent of all captures. M. lucifugus was captured most frequently (48 percent), followed by M. californicus (15 percent), M. evotis (13 percent), M. volans (8 percent), Lasionycteris noctivagans (7 percent) and M. ciliolabrum (7 percent). One specimen each of Plecotus townsendii and Lasiurus cinereus were captured, comprising less than one percent of the total capture. Relative bat abundance varied greatly between 24 sites monitored during the study. High levels of bat activity were found at Camp 32 (74 passes/hr.), Upper Fortine Creek (72 passes/hr.), and Trout Creek (60 passes/hr.). Sites demonstrating the most foraging activity as measured by feeding buzzed per hour were Camp 32 (n=29), Big Creek (n=14) and Bull Lake (n=13). The mean index of bat activity at the 24 transect locations was 33.5 +/- 8.9 passes per hour, and 6.3 +/- 2.7 feeding buzzes per hour (alpha=0.025). Bats were regularly encountered foraging over road, creeks, and ponds in the study area. Of 1,031 bat passes detected at 24 transect locations, 19 percent (n=196) were attempting to capture prey. Foraging activity was highest at Camp 32 where 43 percent of bat passes contained a feeding buzz. Foraging bats were absent at three sites in the study area, but compromised at least 8 percent of all bat passes at every other site. Two adits investigated during this study are utilized by bats as night roosts. Myotis evotis were captured at the entrances of two adits on the Superior Ranger District. The Trout Creek adits, located on the west side of Trout Creek at approximately 3800 ft and 4100 ft elevation, were visited by male and female M. evotis on 13 July. The lower adit contained bat guano and culled moth wings. Only three juvenile bats (2 percent) were captured during the study: two male M. lucifugus at Lower Fortine Creek on 29 August, and one female M. volans at Rock Creek on 27 September. Females comprised 62 of 120 adults captured in mist nets (52 percent). Lactating M. lucifugus, M. californicus, M. ciliolabrum, and M. evotis were captured during the study between 15 July and 1 September. Lactating females represented 7 percent of the total bats captured and 13 percent of adult female bats captured. During the study, 24 percent of adult female bats captured were classified as either lactating (n=8), gravid (n=6), or postpartum (n=1). The observed low fecundity is likely due to the cold and wet weather experienced during the study. Information needs for the effective management of bat populations include knowledge of distribution, population status, and habitat requirements. Echolocation monitoring and mist-netting can provide much-needed information that is the first step towards protecting bat habitat.
