The U.S. Fish and Wildlife Service has proposed a plan to shoot hundreds of thousands of barred owls in West Coast forests over the next 30 years, arguing that the survival of one owl species depends on the extinction of another. The spotted owl, not native to the area, is displacing its genetically related barred owl, the bureau said.
Unless action is taken against barred owls, the spotted owl could disappear from parts of Washington and Oregon within a few years and eventually become extinct, according to service biologists.
This proposal is the latest effort to save the spotted owl, whose decline became a rallying point for environmentalists against logging in the Pacific Northwest in the 1980s. This plan raises questions about how far humans should go to save species and the cost of righting historic ecological wrongs, as the barred owls may have become established in the Pacific Northwest under human influence as European settlers spread westward.
The proposal calls for the “lethal removal” (killing with shotguns) of more than 470,000 barred owls in total and is open for public comment until January 16th. It may be difficult for the undiscerning eye to distinguish barred owls from spotted owls, as both have pale faces and mottled brown and white coats and belong to the same genus. However, barred owls are slightly larger, breed faster, are more aggressive, and are less discriminatory about where they live and what they eat.
The spotted owl population has declined by about 75 percent over the past 20 years, primarily due to barred owls, according to the U.S. Fish and Wildlife Service. The plan would eliminate the barred owls from 1-2% of its current range, and the removal of barred owls has been shown to stabilize the spotted owl population, although the impact has not been substantial.
Despite the dominance of barred owls, the population is likely to recover over time, and the cost of righting historic ecological wrongs is still uncertain. Wildlife biologists consulted with an ethicist about killing the animals, and while some animal rights groups disagree with the plan, a final proposal is expected to be released in the spring or summer after the public comment period on the USFWS proposal ends.
