California Spotted Owl Conservation Strategy

California Spotted OwlThe Forest Service is leading an effort to prepare a Conservation Strategy for the California spotted owl (CSO). The strategy will help conserve and sustain the CSO population in the Sierra Nevada/Cascade region.

This strategy will be useful not only to the Forest Service, but also to other land management agencies and researchers.

Our goal is to complete the strategy in fall 2016.

Northern Spotted Owl Decline Continues

Northern Spotted OwlContinued Decline of the Northern Spotted Owl Associated with the Invasive Barred Owl, Habitat Loss, and Climate Variation

CORVALLIS, Ore. – Northern spotted owl populations are declining in all parts of their range in the Pacific Northwest, according to research published in The Condor. Based on data from 11 study areas across Washington, Oregon and northern California, a rangewide decline of nearly 4 percent per year was estimated from 1985 to 2013.

Researchers found evidence that the invasive barred owl is playing a pivotal role in the continued decline of spotted owls, although habitat loss and climate variation were also important in some parts of the species range. Barred owls compete with spotted owls for space, food and habitat.
