Abstract

Roger Lake Research Natural Area (RNA), a 174.7-ha reserve in north-central Washington, contains a rich diversity of landforms, plant communities, and wildlife habitats. Spreading outward from the lake itself, sedge and sphagnum fens give way to upland coniferous forest, granitic cliffs, and a relictual, high-altitude big sagebrush-whitebark pine (Artemisia tridentata-Pinus albicaulis) meadow. Five sensitive plant species and several vertebrate species that are rare in the region occur in the RNA. Dynamic ecological processes in action in the RNA are revealed in the paludification of the forest edge; aging, broken beaver dams; and widespread bark beetle-induced conifer mortality.
