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 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 economiesThe little brown batworld's longest lived mammal for its size, life-spans sometimes exceeding 32 years. All mammals can contract rabies; however< 0.5% of bats get rabiesnormally bite in self-defensepose little threat to people A colony of 150 big brown bats can protect local farmers from up to 33 million or more rootworms each summer. 7, 8, or 9 WI BAT SpeciesFamily: VespertilionidaeMyotis lucifugus Little brown batMyotis septentrionalisNorthern long-eared Pipistrellus subflavusEastern pipistrelleEptesicus fuscusBig brown batLasiurus borealisRed batLasiurus cinereusHoary batLasionycteris noctivagansSilver-haired bat???

The National Bat Monitoring Programme was intended to fill this gap and provide the information on population so urgently needed for conservation and management.Workshop & VolunteerDistributionsVolunteer Recruitment MethodsTalksWorkshopsWord of MouthRoost owner leafletsBat detector leafletsInternetMagazine ArticlesVolunteer OptionsTransect surveys Hibernacula surveysWaterway routesSummer roost site monitoringEtc.Depending on a volunteers location, training, experience and time availabilityTransect route exampleBat detector surveysRoost site surveysPipistrelle roosts / occasional recordsSerotines present absentWinter & Summer Roost distribution of the Natterers batWinter & Summer Roost distribution of the Serotine batWinter & Summer Roost distribution of the Pipistrelle batWisconsin Bat Conservation & Management Plan (WBCMP)WBCMP 2005The Goals of the WI Bat Conservation & 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.WBCMP Phase IPlan, Infrastructure design, and Methods developmentDevelop Wisconsin Bat Conservation & Management Plan Utilize a statewide GIS-based data mapping system.... Identify issues related to bat impacts...Develop a P.I.T. tag detection & monitoring system.Identify & 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.
