Northwest Forest Plan Book Chapter: Northern Spotted Owl Habitat and Populations

Release Date:

Authors from the U.S. Forest Service and the USGS wrote a book chapter outlining how northern spotted owls shaped the Northwest Forest Plan.

They provide a 20-year synthesis of science focused on the ecology, conservation, and management of northern spotted owls and review expectations for conserving northern spotted owls under the Northwest Forest Plan. Authors review recent information on the status and trends of spotted owl populations and suitable forest, effects of interactions with barred owls, prey ecology, disturbance impacts, climate change, and other threats. They also review population trends and range expansion of barred owls, their habitat and prey, and identify other sensitive wildlife and ecological processes that may ultimately be affected by the invasion of barred owls. In conclusion, they provide considerations for management and research needs for spotted owls and forest types most critical to their persistence. Volumes one, two, and three of the book are available at the U.S. Forest Service Pacific Northwest Research Station’s website.
