Title: Condition and deterioration rate of precommercial thinning slash at False Island, Alaska.

Author: McClellan, Michael H.; Hennon, Paul E.; Heuer, Patrick G.; Coffin, Kenneth W.;

Date: 2014


Publication Series: Research Paper (RP)

Description: We examined slash from thinning treatments in a 21-year chronosequence of young-growth stands in southeast Alaska to determine the strength and persistence of slash effects on two key features of deer habitat quality: forage availability and deer mobility within thinned areas. We describe the main deterioration processes and their dynamics over time. We measured wood density of slash of various ages and present a model to estimate changes in wood density over time. This report also discusses factors that contribute to initial slash loading, slash deterioration, and effects on deer habitat.

Keywords: Thinning, Sitka spruce, western hemlock, southeast Alaska, slash, decomposition, wildlife habitat, Sitka black-tailed deer.
