Northern spotted owls face functional extinction in Pacific Northwest

New research indicates that northern spotted owls are approaching or have already reached functional extinction across significant portions of the Pacific Northwest. Despite decades of conservation efforts following their listing as a threatened species in 1990, populations in Washington and along the Oregon Coast have declined to critical levels.

Researchers noted that no spotted owls were detected in the Washington Cascades at latitudes north of Seattle. The decline is partly attributed to competition from barred owls, which outcompete the northern spotted owl for habitat and prey.

To monitor these trends, scientists utilized artificial intelligence and advanced acoustic monitoring. Experts, including U.S. Forest Service biologist Damon Lesmeister, suggest that future management could include ongoing barred owl removals, landscape conservation for nesting, and captive breeding programs to prevent total loss of the species' ecological role.
