Status of Spotted Owls in NW California and
the Impact of Barred Owls

Barred owl populations have been increasing in the Pacific northwest for several decades and are now impacting northern spotted owls throughout their range. To address this problem, several barred owl removal studies have been initiated which included areas of local long-term demographic studies on Green Diamond property, the Hoopa Reservation, and the Six Rivers and Shasta-Trinity National Forests. Peter Carlson, currently working for Colorado State University as a long-time member of the research team for the studies on national forest lands, will discuss some of the impacts of barred owls, the recent trends of the owls, and status of the removal studies. While the impacts of barred owls are of real concern, that is only one of several ongoing threats to the spotted owl. Peter will also discuss the barred owl issue in the context of multiple stressors.

Peter Carlson began studying spotted owls in the San Bernardino mountains in 1992 and has worked on the NW California demography study since 1994. He has some fond memories of working briefly with barred owls and other raptors, in their native habitat, in Illinois in 1986m prior to beginning his MS work in Wildlife Ecology at the University of Florida. He previously worked for Humboldt State University as the field coordinator for the demography study, and since 2005 has worked through Colorado State University as a Research Associate for the study.
