Recovery Plan for the Northern Spotted Owl - DRAFT

sites on federal lands (figure 3.21). This is a relatively low percentage of knownprotected pairs compared to other provinces. When habitat has recovered onfederal lands within these DCAs, the DCAs are expected to support 205 pairsof spotted owls. The DCAs contain about 53 percent of the nesting, roosting,and foraging habitat located on federal lands in the province (Figure 3.22).Generally, federal matrix forests should be managed under prescription A,providing dispersal habitat on lands outside of DCAs following the 50-11-40guideline. As part of this prescription, residual habitat areas of 100 acresshould be delineated around all known and future-discovered owl activitycenters in the matrix up to a maximum density of 10 areas per township.In addition to prescription A, two zones are recommended for matrix prescriptionB. Reserved pair areas will be established in these locations to supplementthe DCA network where it is deficient. Four reserved pair areas will beestablished around owl activity centers east and south of OD-21. One additionalreserved pair area will be established west of OD-20.Biological goals and implementation on nonfederal landsA large area in the province has been identified for special management emphasis.(Table 3.17.

Habitat information was not available for nonfederal lands.3 Numbers are pairs of spotted owls verified in a 5-year period either 1986 through 1990 or 1987 through 1991.4 This is an estimate of the number of pairs of owls that the DCA would be expected to support on federal lands if the population stabilized withcurrent habitat conditions.
