State Wildlife Grant Bat Monitoring Activities 2012

The Western Great Lakes Bird and Bat Observatory (hereafter described in this report as WGLBBO) was awarded a State Wildlife Grant in 2011 (SWG 11- CAT2 -009); we carried out the field work and other activities described below in 2012.

Included in the activities funded and carried out as part of this grant were (a) bat ecology and monitoring workshops, (b) enlisting and training volunteers to do acoustic monitoring for bats, and (c) coordinating a group of paid surveyors doing a set of WDNR ”Batlas” routes.

Bat Ecology Workshops

Bat ecology and monitoring workshops/presentations were organized and presented by Western Great Lakes Bird and Bat Observatory staff conservation biologist William Mueller throughout January - September of 2012, at most of eastern Wisconsin’s nature centers, and at an array of other public facilities including community centers and public libraries. Workshops covered topics that included bat species of Wisconsin; general ecology and myths concerning bats; migratory species and hibernating species; status of Wisconsin’s bats, economic and ecological importance of bats; bats as providers of ecological services; how volunteers and citizens can assist in bat conservation; threats to bats including White Nose Syndrome and its spread, and wind power and bats; use of acoustic monitoring technology; providing bat houses, roost surveys by WIDNR, and information regarding the Wisconsin Bat Monitoring Program.

Locations and dates of workshops are given below in Table 1.

Paid BATLAS Surveys

Paid surveyors did an extensive subset of WIDNR previously-chosen BATLAS routes (Table 2). We coordinated these surveys with the help of Paul White of WIDNR; (WIDNR personnel and volunteer surveyors also conducted other routes during 2012). One surveyor (Angela Jackson), a UW-Milwaukee graduate student, coordinated her surveys with WGLBBO, her major professor Dr. Glen Fredlund (Director of the Conservation and Environmental Studies Program and the UW-Milwaukee Department of Geography) , along with Dave Redell and Paul White of WIDNR, using the data collected as part of her master’s thesis research at UW-Milwaukee.

Volunteer Surveys

We coordinated, trained and assisted volunteer surveyors in completing a number of acoustic monitoring routes for bats in many southeastern Wisconsin locations. Examples of monitoring route results as mapped by WIDNR from bat acoustic data are given below. 

To understand the maps and their symbols, please see this (abbreviated) legend from the WI Bat Monitoring Program.

“The maps display the route surveyed superimposed on an aerial photograph. Bat encounters along the route are indicated by a symbol that represents the species or group”. These symbols are explained below:

Species & Groups

Within Group Classification

image001  High Frequency Group (HFG) includes:

image002 Myotis

image003 MYLU = Myotis lucifugus [Little brown myotis]

image004 MYSE = Myotis septentrionalis [Northern long-eared myotis]

image005 Labo / Pesu

image006 LABO = Lasiurus borealis [Eastern red bat]

image007 PESU = Perimyotis {=pipistrellus} subflavus [Eastern pipistrelle]

image008 Low Frequency Group (LFG) includes:

image009 LACI = Lasiurus cinereus [Hoary bat]

image010 Epfu / Lano

image011 EPFU = Eptesicus fuscus [Big brown bat]

image012 LANO = Lasionycteris noctivagans [Silver-haired bat]

Notes

  • Currently, some species are grouped together to prevent misidentification (e.g. EPFU and LANO, and the Myotis species) due to similarities between calls.
  • As additional reference calls / passes from species of known individuals (identified in hand after capture and recorded upon release) are added to the reference library we will further distinguish within each species group.
