Scientific research for the conservation of the species
The objectives of the program are to: (i) identify anthropogenic structures in Prince Albert National Park (PANP) that are used as roosting sites by LBMY; (ii) assess occupancy of roosting sites and colony size over time; and (iii) return an inventory of bat species present in PANP. Bats will be captured using mist nets, which is a common technique for surveying bats as part of species inventories (Kunz and Kurta 1988, Vonhof 2010). Mist netting will occur on a maximum of 6 nights, with anywhere from 0 – 100 bats captured each night of the survey. Approximately 10 minutes/bat is required for taking body measurements, identifying the species, sexing the individuals and taking wing swabs. Noticeably pregnant bats will be released immediately. Depending on funding availability, mist-netting surveys may be repeated in different areas of the park over multiple years, in order to return a more precise picture of the PANP bat community.

Location of Activity (province, territory or ocean):
Alternatives: The alternative of solely using acoustic devices is an option and has been a useful tool to identify and confirm bat presence at sites. However, acoustic monitoring devices are limited in their accuracy of identification of bat species (Lemen et al. 2015). Furthermore, detection of LBMY through acoustic monitoring does not inform on roost occupancy nor the size of the colony utilizing the roosts. Mist-netting is the best alternative that will support the achievement of the objectives of this program with minimal disturbance to the bats. Not conducting the survey would prevent PANP from acquiring useful and critical information required to make informed decisions on bat conservation and management. Mitigations: Bats appear resilient to capture and handling, and few bats are injured or killed because of capture surveys. However, the risk of injury or death to bats will be further minimized through the following mitigation measures: (1) capture and handling will be overseen by an experienced bat biologist; (2) nets will be checked every 10 – 15 minutes to minimize the time the bats are in the nets; (3) field crews will carry a cutting tool in case bats cannot be quickly extracted from the nets; (4) bats will be temporarily held individually in soft cloth bags; (5) netting will end by 1 hour before sunrise and all bats will be released before dawn to reduce risk of predation by birds; (6) pregnant or injured bats will be released without a holding period for further processing; (7) nets will be temporarily closed if the capture rate exceeds operational capacity; and (8) netting will not occur in cold or rainy weather. Jeopardy to Survival or Recovery: The treatment of bats will be consistent with the Guidelines of the American Society of Mammalogists for the Use of Wild Animals in Research (Gannon and Sikes 2007), and no bats are anticipated to be harmed as part of this study. As the threat to bat populations in North America is due to the fungus that causes White-nose Syndrome, this project is not expected to exacerbate that threat or jeopardize survival or recovery of the species. Locating bat roost sites in the park will increase the ability of the park to protect those sites.
