Abstract
Surveys were conducted to determine the presence, relative abundance, and habitat relationships of the breeding bird community on a private industrial forest (21,600 ha) in western Washington. A total of 284 and 299 point counts (8 min duration) were established in 1995 and 1996, respectively, along unpaved logging roads separated by a minimum distance of 240 m. The counts were performed twice, at least 10 days apart. A total of 9,491 detections of 78 species of breeding birds were detected at point count stations during the survey period with 40 species having gt 30 detections. A GIS analysis of forest habitat types was run for a 100-m radius circle centered on each survey point. Of 61 species tested by multiple regression analysis, significant positive regressions were revealed for the following habitat types: mature conifer habitat ( gt 45 yr) for 32 species, pole-sized conifer habitat (27-44 yr) for 27 species, sapling-sized conifer habitat (6-26 yr) for 38 species, recent clearcut habitat (0-5 yr) for 32 species, nonforested habitat (including open water) for 20 species, and alder-hardwood habitat (all ages) for 19 species. Overall, the GIS-habitat/multiple regression models demonstrated that all successional stages on an industrial forest were important to different groups of species within the breeding bird community. Species richness was equal or greater than observed in studies conducted on federal lands in the Pacific Northwest and suggested that industrial forests can be managed to make an important contribution to regional biodiversity of breeding birds
