Northern spotted owls face threat from invasive barred owls

The northern spotted owl faces a significant threat from the invasive barred owl, which is aggressively outcompeting the native species for territory and food. Research from the Integral Ecology Research Center in California indicates that barred owls are heavily utilizing the old-growth forest stands that spotted owls rely on for nesting and roosting. GPS tracking data shows that barred owl home ranges overlap with spotted owl habitats by an average of 64%, often occupying the most structurally complex forest areas.

In response, the US Fish and Wildlife Service has implemented a Barred Owl Management Strategy. This plan involves the removal of up to 15,600 barred owls annually in Washington, Oregon, and Northern California over the next 30 years. The initiative is estimated to cost as much as $1.35 billion. While intended to protect the dwindling spotted owl population, the strategy has faced opposition from animal rights groups and sparked debate regarding the ethics of large-scale predator removal.
