Bats of Clayoquot Sound
from the Raincoast Education Society, Tofino
Witches, goblins, giant spiders and bats are among some of the characters associated with the frights of Halloween. Through the ages, bats have been vilified as blind, diseased, bloodsucking vampires. Their frightening reputation, however, keeps people form learning about the true nature of these vulnerable and fascinating creatures.Scientists classify bats in the mammalian order Chiroptera, meaning “handwing.” With about 1000 species, bats constitute nearly one-quarter of the known mammalian species!
Twenty bat species inhabit Canada. Sixteen of these live in British Columbia.
These nocturnal furry mammals perform invaluable ecological roles: pollinating flowers, dispersing fruit seeds and, in their role as predators, keeping insect populations in check. Having very few natural enemies, bat populations are most seriously impacted by human activity. Many bat species rely on ponds and marshes for foraging, trees and snags for roosting, and caves for hibernating.
Increasingly, each of these habitat types is being changed or destroyed by human activities. To date, eight of BC’s 16 species are considered “at risk”.
In order to assist the planning of protected habitats and appropriate ecosystem management guidelines in Clayoquot Sound, the Scientific Panel and a local planning team commissioned an inventory of the resident bat species.
In 1996, three biologists began this study and their results to date have confirmed the presence of seven local bat species: the Western Long-eared Myotis, California Myotis, Yuma Myotis, Little Brown Myotis, Silver-haired Bat, Big Brown Bat and Keen’s Long-eared Myotis.
Discovery of BC’s endangered Keen’s Long-eared Myotis is especially significant because so few known locations of this species exist. It would be a real treat to spot him on your prowls on the eve of Halloween.
