Abstract
The ecology of landscape-scale processes is richly expressed in forested mountain landscapes of western Oregon and Washington in northwestern North America (Figure 1). The mosaic of landscape patterns is especially dynamic in these geomorphically active areas of high relief, heavy precipitation, and frequent disturbance by fire, wind, and other processes. Indeed, the time scales of geomorphic and ecosystem change overlap in these areas of active volcanism, unstable hillslopes, and long-lived trees. Mount St. Helens in Washington State, for example, has had eruptive episodes over the last 2500 years, interspersed with dormant periods lasting 200 to 700 years (Mullineaux and Crandell, 1981). The eruptions have altered the surrounding conifer forests, dominated generally by Douglas fir (Pseudotsuga menziesii), which can live well beyond 1000 years.
