Officials have killed nearly 650 barred owls in the Pacific Northwest. That’s one of the findings of a new report on the first 21 months of an effort to protect northern spotted owls from invasive barred owls.
The progress report was produced by the U.S. Geological Survey and Oregon State University. It looked at test areas near Cle Elum, Washington, and Eugene and Klamath Falls in Oregon.
Federal agencies are in the midst of a five-year experiment to see if killing barred owls can slow or reverse rapid declines in northern spotted owl populations.
Report authors say results are inconclusive in all three test areas, but there’s early indication that barred owl removal could be linked to spotted owl survival in Oregon’s Coast Range.
