Abstract
Abstract Avian surveys were conducted from May-July, 1985 on four study areas in the Moshannon State Forest, Clearfield Co., PA. We compared bird populations and communities in Timber Stand Improvement areas to Timber Stand Improvement areas with snags retained (TSI vs. TSI + SNAG, respectively). Bird numbers averaged 1.7 times higher on the TSI + SNAG area than on the TSI area. Average species richness also was significantly higher on TSI + SNAG. Retention of snags was important to bark-gleaning and cavity-nesting birds. During TSI operations, forest managers can improve habitat for cavity-nesting and bark-gleaning birds by leaving snags. The costs of leaving snags is low, and the long-term benefits provided by insectivorous birds outweigh the costs. North. J. Appl. For. 7(1):35-38, March 1990.
