It is an offence to conduct a survey or census of wildlife or wildlife behaviour, administer drugs, collect or purchase specimens, or carry out any scientific research relating to wildlife without a permit. The Department of Environment and Natural Resources (ENR) is responsible for issuing Wildlife Research Permits. Each year, researchers carry out studies on all types of wildlife and wildlife habitat, throughout the NWT. As a requirement of an NWT Wildlife Research Permit, researchers must submit a summary report of their activities and findings to ENR. These summary reports are published each year in an annual report. This publication provides summary reports for the wildlife research carried out during 2011. Contact information for the main investigator leading each project has been included if you wish to obtain more information on a specific project. For more information on Wildlife Research Permits, please go to www.enr.gov.nt.ca or contact your local Environment and Natural Resources office. The contents of each summary are the sole responsibility of the team leads for each project and do not reflect any official policy of ENR or the Government of the Northwest Territories (GNWT).

Little is known about bat diversity in the Northwest Dr. Cori Lausen, Independent Research Biologist, Territories (NWT). One of the four main bat hibernacula Bat Specialist known in Alberta is in Wood Buffalo National Park (WBNP). It was thus hypothesized that bats also hibernate Wildlife ResearCh PerMit NuMBer: in NWT areas around WBNP. WL004812 oBJeCtives: LOCATION: ´ To locate bat hibernacula; and The study took place in the Fort Smith area, around ´ To determine what species of bats are still present Wood Buffalo National Park (South Slave Region). in NWT in mid-September, during the mating period PARTNERS: just prior to hibernation. ´ Parks Canada METHODS: ´ Environment and Natural Resources (GNWT) We used information from local residents regarding ´ Birchdale Ecological Ltd. potential bat hibernacula in caves, and investigated these areas. Using mist nets for bats captured, and bat detectors CONTACt: to record ultrasounds we inventoried the general area Dr. Cori Lausen to determine species diversity at this time of year. Independent Research Biologist, Bat Specialist IRDF Research Fellow, RESULTS AND Main.ConCLUSIONS: Wildlife Conservation Society Canada We determined that there are three species of bats that PO Box 606 overwinter in this region of the NWT: big brown bat Kaslo, BC V0G 1M0 (Eptesicus fuscus), little brown myotis (Myotis (P) 250-353-7339 lucifugus), and northern myotis (Myotis septentrionalis). (E) [email protected] We located one major hibernaculum, containing approximately 3,000 individuals (almost exclusively males). Captures in the vicinity of this cave were of all three species, but internal observation was only of little brown myotis. There are many fissures inside this cave that could be used by big brown bats and northern myotis, and thus these species may also be hibernating in this cave, but they were not visible. The bat hibernaculum located during the study is the largest bat hibernaculum currently known in western Canada. 8 2011 Annual Report of NWT Wildlife Research Permits Wildlife Species Research: Bats LONG-terM.plans.. more likely to be detected from airplane. This may lead and.reCoMMENDATIONS: to finding mixed species hibernacula. The following recommendations are made regarding Locate local Myotis lucifugus maternity colonies. This the South Slave Region and the surrounding WBNP area: will provide opportunity to radio track adult females at Acoustic monitoring year-round along Highway 5 in the end of the summer to potentially locate hibernacula; WBNP to determine if this highway is a migration route this may facilitate an understanding of the male bias in for bats in the spring and/or fall. Simultaneous monitoring the hibernacula and mist net captures during this study. along the Slave and Peace Rivers may also illustrate Exploration and late summer investigation of sinkholes patterns of bat migration especially that of the known by local people, such as in the Lobstick Creek area. tree-roosting bats (hoary, red and silver-haired) that are likely to move out of the area by late summer. CoMMunitY INVOLVEMent: Following the inventory work, I made a public presentation Summer bat surveys (acoustic and capture). It would about bats including the findings from this survey at the be especially interesting to determine whether big brown Parks Canada office in Fort Smith, NWT. bats reside in the area during summer given its absence from the Fort McMurray / Fort McKay areas to the south of WBNP. Monitoring of the hibernacula described in this survey, including regular annual or biennial inspections (counts and checking for signs of White-Nose Syndrome). Acoustic monitoring year-round would be informative to understand patterns of use. Periodic mist netting would allow for patterns of use by species and sex to be known. Continuous population estimates will be needed to monitor this hibernaculum
