Washington State’s contribution to owl recovery on non-federal lands was developed through a collaborative stakeholder process, and adopted into law in 1996. In the 1990s the Spotted Owl was catapulted into the spotlight over logging debates in the Pacific Northwest. In 1990, the number one threat to the Northern Spotted Owl was habitat loss. barred owl encroachment into spotted owl habitats may be beyond the scope of the Plan, but maintaining large blocks of suitable spotted owl habitat will likely play a key role in decreasing negative interactions between the two species and increasing the likelihood of the persistence of spotted owl populations. Management plans for the Northern Spotted Owl. back to 2008 Final Revised Critical Habitat for the Northern Spotted Owl website The lidar-based map … Habitat classifications are based on gradient nearest neighbor (GNN) models using Landsat TM and environmental predictor variables (Davis et al., 2011, Ohmann and Gregory, 2002). Details for map development are explained in detail in Appendix C of the 2011 Revised Recovery Plan for the Northern Spotted Owl (USFWS 2011) and the Modeling Supplement (Dunk etal 2012) for Final Critical Habitat for the Northern Spotted Owl. Northern Spotted Owl Recovery Information Site Maps : Final Critical Habitat . At night it silently hunts small mammals such as woodrats and flying squirrels. This large, brown-eyed owl lives in mature forests of the West, from the giant old growth of British Columbia and Washington, to California's oak woodlands and the steep canyons of the Southwest. The timber industry feared that if the northern spotted owl was protected by the federal government, they would be forced to slow or stop logging in some areas. The USFWS Oregon Fish and Wildlife Office works closely with our partners in Oregon and neighboring states to conserve fish, wildlife, plants and habitat. PDF Format. We explored the differences and similarities between these maps, and to a pre-existing aerial photo-interpreted habitat map produced by local wildlife biologists. The Northern Spotted Owl is getting a new level of protection across hundreds of miles of its range. Best Management Practices for Managing Spotted Owl Habitat July 7, 2009 Page 1 1 Introduction In May 1997, the provincial government approved the Spotted Owl Management Plan (referred to in this document as SOMP 1) for the Chilliwack and Squamish Forest Districts to provide a reasonable probability that the Northern Spotted Owl (Strix Habitat loss was listed as a major contributor to the birds' "threatened" status. Range-wide map of northern spotted owl habitat in the Pacific Northwest of the United States and location of the study area on the Willamette National Forest. They usually nest in the tall old trees in parts of Oregon to the southwest part of Canada. The northern spotted owl primarily inhabits old growth forests in the northern part of its range (Canada to southern Oregon) and landscapes with a mix of old and younger forest types in the southern part of its range (Klamath region and California).The subspecies' range is the Pacific coast from extreme southern British Columbia to Marin County in northern California. Distribution and habitat. A nesting pair of Spotted Owls requires from 2000 to 5000 acres of conifer forest, chiefly Douglas-fir. Washington breeders represent the northern subspecies , S. o. caurina. mates of habitat area between Landsat-based and lidar-based northern spotted owl SDMs and habitat maps. Current management plans for Spotted Owls provide habitat for 1500 - 2000 territories, clustered in groups to aid in juvenile owl dispersal.
