Forest Management and Bats
F orest Management a n d B a t s | 1 Forest Management and Bats F orest Management a n d B a t s | 2 Bat Basics More than 1,400 species of bats account for almost a quarter of all mammal species worldwide. Bats are exceptionally vulnerable to population losses, in part because they are one of the slowest-reproducing mammals on Earth for their size, with most producing only one young each year. For their size, bats are among the world’s longest-lived mammals. The little brown bat can live up to 34 years in the wild. Contrary to popular misconceptions, bats are not blind and do not become entangled in human hair. Bats are the only mammals capable of true flight. Most bat species use an extremely sophisticated biological sonar, called echolocation, to navigate and hunt for food. Some bats can detect an object as fine as a human hair in total darkness. Worldwide, bats are a primary predator of night-flying Merlin Tuttle insects. A single little brown bat, a resident of North American forests, can consume 1,000 mosquito-sized insects in just one hour. All but three of the 47 species of bats found in the United States and Canada feed solely on insects, including many destructive agricultural pests. The remaining bat species feed on nectar, pollen, and the fruit of cacti and agaves and play an important role in pollination and seed dispersal in southwestern deserts. The 15 million Mexican free-tailed bats at Bracken Cave, Texas, consume approximately 200 tons of insects nightly. -

Nine Species of Bats, Each Relying on Specific Summer and Winter Habitats
Species Guide to Vermont Bats • Vermont has nine species of bats, each relying on specific summer and winter habitats. • Six species hibernate in caves and mines during the winter (cave bats). • During the summer, two species primarily roost in structures (house bats), • And four roost in trees and rocky outcrops (forest bats). • Three species migrate south to warmer climates for the winter and roost in trees during the summer (migratory bats). • This guide is designed to help familiarize you with the physical characteristics of each species. • Bats should only be handled by trained professionals with gloves. • For more information, contact a bat biologist at the Vermont Fish and Wildlife Department or go to www.vtfishandwildlife.com Vermont’s Nine Species of Bats Cave Bats Migratory Tree Bats Eastern small-footed bat Silver-haired bat State Threatened Big brown bat Northern long-eared bat Indiana bat Federally Threatened State Endangered J Chenger Federally and State J Kiser Endangered J Kiser Hoary bat Little brown bat Tri-colored bat Eastern red bat State State Endangered Endangered Bat Anatomy Dr. J.

Resource Utilization by Foraging Eastern Red Bats (Lasiurus Borealis) in the Ozark Region of Missouri
The Journal of Wildlife Management 78(3):483–493; 2014; DOI: 10.1002/jwmg.685 Habitat Relations Resource Utilization by Foraging Eastern Red Bats (Lasiurus borealis) in the Ozark Region of Missouri SYBILL K. AMELON,1 Northern Research Station, U.S.D.A. Forest Service, 202 Natural Resource Building, Columbia, MO 65211, USA FRANK R. THOMPSON III, Northern Research Station, U.S.D.A. Forest Service, 202 Natural Resource Building, Columbia, MO 65211, USA JOSHUA J. MILLSPAUGH, University of Missouri, 302 Natural Resource Building, Columbia, MO 65211, USA ABSTRACT Resource selection by animals influences ecological processes such as dispersal, reproduction, foraging, and migration. Little information exists regarding foraging resource selection by bats during the maternity season. We evaluated support for effects of landcover type, landform, and landscape pattern on resource selection by individual foraging female eastern red bats (Lasiurus borealis) during the maternity period and compared resource utilization for all individuals pooled (population level), individuals grouped by geographic location, and individuals grouped by stage of lactation (early, mid, and late). We used a resource utilization function (RUF) to relate landcover and landscape attributes to the utilization distributions of individual bats estimated by the fixed-kernel method. We radio-tracked 64 lactating red bats and estimated utilization distributions for 52 individuals. Mean home range size ranged from 1,041 to 1,588 ha from late to mid lactation. The global RUF model was significantly better than the null RUF model for 36 (70%) individuals and the magnitude and direction of coefficients varied among individuals. Resource utilization at the population level was, on average, positively related to ridges and upland drainage landforms, water landcover, and road density; and negatively related to urban and nonforest landcover and distance to edge. -

Bats and Wind Turbines
March 2017 ISSUE BRIEF Bats and Wind Energy Background About Bats Of the 47 bat species that occur in Canada and the U.S., all but two are voracious consumers of insects, including many agricultural and forestry pests.1,2 Pest control services provided by bats reduce both the number of pests and the amount of pesticides required to con- trol them, and these services have been valued at more than $3.7 billion USD/year.3,4,5 The other two bat species, mostly prevalent in the Southwestern U.S., feed on the nectar of agave cactuses com- monly used to produce tequila and are critical pollinators for these plants.6,7 Bats face numerous threats, including climate change, habitat loss and degradation, persecution, White Nose Syndrome (WNS) and other diseases, and fatalities at wind energy facilities.8,9 Some of these threats, such as climate change and habitat loss and degrada- tion, affect all species, whereas others, such as WNS, affect species with certain ecological and behavioral characteristics (e.g., hibernat- ing in cold caves). Bats are long-lived and reproduce slowly, typically only having one to two pups a year and not every year, which limits their ability to sustain such threats and puts them at increased risk of population decline. MEXICAN FREE-TAILED BATS EXITING BRACKEN BAT CAVE, PHOTO BY USFWS HEADQUARTERS, FLICKR Bats and Wind Turbines Throughout the 1990’s, wind energy facilities did not report bat fa- ally been highest in the deciduous forests of the Northeast and low- talities for a variety of reasons: 1) no bat fatalities occurred at fa- est in the open range desert of the Great Basin/Southwest. -
