Coastal screech-owls on Vancouver Island are endangered due to habitat loss and competition, needing old growth forests for survival.
Coastal screech-owls on Vancouver Island, a threatened subspecies, depend on old growth forests like coastal Douglas fir and Garry oak ecosystems for survival, according to ornithologist Megan Buers.
Their numbers have declined due to logging, development, and competition with barred owls, with populations now rare on the island’s east coast.
Research using tracking tags shows they rely on dense old growth areas for hunting small mammals, snails, amphibians, and fish.
Buers stresses that restoring native plants and prey species is key to recovery, and she believes the island could support three to four times its current owl population if habitats were protected and restored.
Individuals can help by planting native species, preserving dead trees, and installing nest boxes.
