Scientific research for the conservation of the species
The goal of this research is to study how bats utilize the Southern Gulf Islands as a migratory corridor using stable isotope methods. The researchers will use mist netting methods to capture bats in flight at multiple sites in the Gulf Islands National Park Reserve throughout the migratory period: late August until late October. Once captured, individual bats will be identified to species, physical measurements will be taken, a small hair sample will be clipped from their dorsal side, and the bat will be promptly released. The hair samples will be sent to a laboratory to determine their stable isotope composition, which will provide novel information regarding the movements of bats in Coastal British Columbia.

Alternatives: A review of the current literature shows that very little data are available on the migration of little brown myotis. Too few preserved museum specimens have been collected in the southern Gulf Islands to provide conclusive results. Most methods of migration tracking are more invasive than the chosen stable isotope method. Radio and GPS tracking, as well as banding and tagging, also require capture. Additionally, the equipment required may burden or injure the study animal. In regards to not undertaking this activity, such an inaction would likely degrade our ability to assist this species’ recovery. Understanding the seasonal movements of this species will help predict the spread of the disease and direct monitoring efforts. Mitigations: To reduce the amount of time individual bats will spend entangled in the nets, the nets will be tended continuously and checked with a light every five minutes. If a bat cannot be disentangled after five minutes of being discovered, the net will be cut to reduce stress to the animal. The researcher will minimize direct handling of the animals, so as to reduce stress and the risk of capture myopathy. In the unlikely event that a bat is injured during capture and needs to be rehabilitated, it will be transferred to the BC SPCA’s Wildlife Animal Rehabilitation Centre. If a bat is severely injured, it will be euthanized so as to not prolong suffering. Steps will be taken to ensure there is no disease transmission between individuals and between sites. Equipment will be decontaminated and/or disinfected to prevent the spread of pathogens such as white-nose syndrome. Jeopardy to Survival or Recovery of the Species: The distribution objective for little brown myotis is to maintain (or where applicable restore to) the pre-white-nose syndrome extent of occurrence. It’s important to note that, while the little brown myotis is endangered federally, it’s believed that populations outside of areas affected by white-nose syndrome, such as British Columbia, are generally stable or increasing (COSEWIC 2018). The population objective in areas not yet affected by white-nose syndrome (such as in British Columbia) is to maintain a stable population trend, or if possible, achieve an increasing population trend. As this activity is not expected to cause mortality or influence reproductive rates, it is unlikely to have residual detrimental impacts and is not expected to adversely affect the ability to achieve population and distribution objectives for the species. Although this research may cause short-term stress for a limited number of individuals, the knowledge gained could greatly benefit the broader population over the long term by helping to identify critical habitat for protection and predict the spread of white-nose syndrome in western Canada.
