Effects of Bark Fragmentation on Plant Succession on Conifer Logs in the Picea-Tsuga Forests of Olympic National Park, Washington
Harmon ME. 1989. Effects of Bark Fragmentation on Plant Succession on Conifer Logs in the Picea-Tsuga Forests of Olympic National Park, Washington. The American Midland Naturalist. 121(1):112-124
From the Abstract: "Plant succession on Picea (spruce), Pseudotsuga (Douglas fir) and Tsuga (hemlock) logs in the Hoh Rain Forest, Washington, was examined using the chronosequence method. Bark fragmentation patterns differed among these species, Picea and Tsuga logs lost their bark in 60 years and Pseudotsuga in 190 years. ... Modeling indicates differences in succession patterns among species of logs were caused by differences in bark fragmentation patterns. Although logs are a major seedbed in Picea-Tsuga forests, self-thinning, bark fragmentation and toppling of trees greatly reduced lonng-term survival on logs." Study area within Olympic National Park, WA.
