Spotted owl monitoring in Olympic National park 1999 annual report
Gremmel S and Seaman DE. 2000. Spotted owl monitoring in Olympic National park 1999 annual report. Olympic National Park
This report summarizes progress on the northern spotted owl monitoring project in Olympic National Park (OLYM) in 1999. Monitored owl sites in OLYM, together with those visited by PNW crews on Forest Service land on the Olympic Peninsula, make up the Olympic demographic study area. This is one of eight areas monitored to assess the effectiveness of the Northwest Forest Plan in preventing a further decline in spotted owl populations. Specific objectives are to: 1) Document age-specific survival and fecundity to contribute to a range-wide assessment of trends in spotted owl populations required by the effectivess monitoring component of the Northwest Forest Plan; 2) Monitor park-wide patterns in spotted and barred owl occurrence, and identify factors which could predict them. The invading barred owl has only been found in the park interior since the mid-'90's, and competition between these closely related species could profoundly alter the distribution of spotted owls.
