Experimental Removal Results and Implications for Managing Barred and Spotted Owls

The northern spotted owl, federally listed under the Endangered Species Act in 1990, represents an icon of old-growth forest protection in the Pacific Northwest. However, despite two-plus decades of intensive habitat conservation and preservation, the owl continues to experience population declines throughout its range. Evidence now suggests that focusing on habitat alone may not be enough to recover the spotted owl. A new threat has recently emerged in the form of an invasive, but closely related competitor: the barred owl.

Please join the Eastside Audubon Society as Dr. Lowell Diller discusses the results of the first barred owl removal experiment and the controversial future potential conservation efforts surrounding the recovery of the northern spotted owl. As the former senior biologist for Green Diamond Resource Company, Dr. Diller has dedicated over 25 years to the research and conservation of the owl and currently serves as an adjunct professor and research associate at Humboldt State University in coastal northern California. His most recent research efforts are focused on understanding the impacts of barred owls on spotted owls and developing a management strategy that will allow spotted owls to persist in the face of the ever increasing threat from barred owls.
