An intensive study was conducted at Ft. Leavenworth Military Reservation (FLMR), Kansas to
determine the presence of all bat species on the base, but special emphasis was placed on the
endangered Indiana bat, Myotis sodalis. This species has not been documented in Kansas
(3D/Environmental Services 1993), but reproductively active individuals have been observed
approximately 160 km (100 mi) east and northeast of FLMR in Caldwell and Nodaway counties,
Missouri. Because habitat similarities do exist, it is reasonable to expect that Indiana bats may
occur in suitable habitat near the Missouri River.
METHODS
Survey methods were based on the recommended mist netting protocol provided by the Indiana
Bat Recovery Team (U.S. Fish and Wildlife Service 1999) in conjunction with Anabat II bat
detectors and a species identification program using a call library that includes species known to
be in eastern Kansas or adjacent Missouri (Britzke et al. 2002, Murray et al. 1999, 2001).
Methods used consisted of a number of mist net sets (two nets not closer than 60 m from each
other) in appropriate areas in the floodplain and upland forests. One bat detector, recording call
sequences to a laptop computer, was set up at each net set and left to record throughout the night,
weather permitting. The protocol recommends that the nets be set for two nights in the same
location. Data presented here are from 8–13 July 2002 and represent the first night of the survey
for each net set, and from May 31 through June 4, and July 17 and 18, 2003 that represent the
second night of the survey for localities 1-10, and two nights at locality 11. Data from each net
(A, B) at a site were pooled for each year, then combined for the final results.
