NANAIMO, BC — Dead or dying trees, also called snags, are sometimes viewed as an eyesore, but a B.C. scientist is warning that if they don’t present a safety hazard, it’s important to leave them be. “There’s systematic elimination of those roost trees and habitat trees because of forestry and safety concerns, residential and agricultural development – we have so few snags in our environment and so many species require them,” said wildlife conservation biologist Christoph Steeger at a presentation this month in Nanaimo. Steeger has spent a career researching wildlife trees, and his work has included a preliminary assessment of the effectiveness of wildlife tree retention. “Because of forestry and other forces there are hardly any left and that’s of grave concern.” His talk was titled ‘the importance of wildlife trees for bats’.
