Order-Chiroptera~1000 known bats - about 1/4 of all mammals. Among mammalian orders, bats are probably unsurpassed in terms of ecological and morphological diversity.Bats are an important natural predator of night-flying insects in WI </p></li><li><p>Bats are vulnerable to extinctionslowest reproducing mammals for their sizemost producing only one young annually. More than 50% of American bat species are in decline or already listed as endangered Loss of bats increases demand for chemical pesticides can jeopardize whole ecosystems of other plant and animal spp can harm human economies</p></li><li><p>The little brown batworld's longest lived mammal for its size, life-spans sometimes exceeding 32 years. All mammals can contract rabies; however&lt; 0.5% of bats get rabiesnormally bite in self-defensepose little threat to people </p><p>A colony of 150 big brown bats can protect local farmers from up to 33 million or more rootworms each summer. </p></li><li><p>7, 8, or 9 WI BAT Species</p><p>Family: VespertilionidaeMyotis lucifugus Little brown batMyotis septentrionalisNorthern long-eared Pipistrellus subflavusEastern pipistrelleEptesicus fuscusBig brown batLasiurus borealisRed batLasiurus cinereusHoary batLasionycteris noctivagansSilver-haired bat</p><p>??? Myotis sodalis Indiana bat??? Nycticeius humeralis???Evening bat </p></li><li><p>UKDespite the best efforts of many committed naturalists and biologists providing data on localised populations of bats, there has been no structured framework for monitoring bat populations at a national level. The National Bat Monitoring Programme was intended to fill this gap and provide the information on population so urgently needed for conservation and management.</p></li><li><p>Workshop &amp; VolunteerDistributions</p></li><li><p>Volunteer Recruitment Methods</p><p>TalksWorkshopsWord of MouthRoost owner leafletsBat detector leafletsInternetMagazine Articles</p></li><li><p>Volunteer OptionsTransect surveys Hibernacula surveysWaterway routesSummer roost site monitoringEtc.</p><p>Depending on a volunteers location, training, experience and time availability</p></li><li><p>Transect route example</p></li><li><p>Bat detector surveysRoost site surveysPipistrelle roosts / occasional recordsSerotines present absent</p></li><li><p>Winter &amp; Summer Roost distribution of the Natterers bat</p></li><li><p>Winter &amp; Summer Roost distribution of the Serotine bat</p></li><li><p>Winter &amp; Summer Roost distribution of the Pipistrelle bat</p></li><li><p>Wisconsin Bat Conservation &amp; Management Plan (WBCMP)</p></li><li><p>WBCMP 2005The Goals of the WI Bat Conservation &amp; Management Plan A functional plan that sets future directions and adapts to new information.Identify where on the landscape Wisconsins eight known species of bats exist throughout their entire natural history cycle, including habitat relationships. Identify the geography, behavior and variability associated with their nightly and seasonal movements. Locate areas in Wisconsin having high and low relative abundance of each bat species. Monitor and identify statewide population trends.Outline conservation needs, priority management actions, and ways to measure plan effectiveness. Utilize the information gathered in a management of natural resources contextspecifically, having the best available information, collected, analyzed, interpreted and readily accessible to all appropriate decision makers.</p></li><li><p>WBCMP Phase IPlan, Infrastructure design, and Methods developmentDevelop Wisconsin Bat Conservation &amp; Management Plan Utilize a statewide GIS-based data mapping system.... Identify issues related to bat impacts...Develop a P.I.T. tag detection &amp; monitoring system.Identify &amp; survey known and possible bat hibernacula.Develop reference library of bat echolocation calls for species ID model.Develop system for monitoring major hibernacula. Develop statewide citizen-based monitoring network for monitoring bat activity on the landscape. </p></li><li><p>Using meaningful classifications for analyses</p></li><li><p>Western Coulee &amp; Ridges Ecological Landscape</p></li><li><p>North Central Forest Ecological Landscape</p></li><li><p>Detecting, Recording, and Analyzing Bat Vocalizations </p></li><li><p>Capture MethodsHarp Traps</p></li><li><p>Reference Call LibraryChemoluminescent tags on released bats </p></li><li><p>Big brown bat Little brown bat- Species Reference -Ultrasound detector recordings</p></li><li><p>Eastern Red bat Hoary bat</p><p>- Species Reference -Ultrasound detector recordings</p></li><li><p>Eastern Pipistrelle Silver-haired batReferenceUltrasound detector recordings</p></li><li><p>Example of variation in a single pass of one species</p></li><li><p>Long-term monitoring stationbat detector &amp; weather data </p></li><li><p>Hibernacula MonitoringMonitor changes in populationsIdentify natural population dynamicsIdentify significant trendsOutline conservation actions</p></li><li><p>Infrared beam-break counters</p></li><li><p>Infrared photo-beam calibration INcountsOUT countsIN OUT = Net movement (Census)</p></li><li><p>Comparing counts for 2 years</p></li><li><p>Thus, an estimate for the over-wintering bat population at the Neda Mine is between </p><p>140,223 and 146,083 bats</p><p>How many bats at other WI hibernacula ?
