Notes: Effects of Precommercial Thinning on Understory Vegetation and Deer Habitat Utilization on Big Level Island in Southeast Alaska
Available evidence suggests that many wildlife species are affected by the low understory production that characterizes closed-canopy, even-aged stands in southeastern Alaska (Wallmo and Schoen 1980; Alaback 1982; Van Horne 1981, 1982; Kessler and Kogut 1985). Precommercial thinning has been suggested as a method of prolonging or maintaining understory as young clearcuts develop into pole stands (United States Department of Agriculture 1986). Information on the effects of thinning on understory growth and the response of wildlife to thinning in southeastern Alaska is lacking. This study reports on the effects of precommercial thinning on understory development and utilization by Sitka black-tailed deer (Odocoileus hemionus sitkensis) on a small island 18 years after treatment.
