Lakeshore vegetation of Sky Lakes Wilderness Study Area, Oregon

Eleven vegetation types occurring within two communities have been described for the lakeshore habitat of the Sky Lakes area. The shrub-dominated community has two closely related heath shrub types. The herb-dominated community comprises a diversity of types ranging from monotypic stands of sedge growing in standing water to more mesic meadows supporting sedge, grass, and herb mixtures. It is proposed that eleven vegetation types can be arrayed along a soil moisture gradient. Microtopographical influences, elevation, and succession interact with the soil moisture gradient to produce a diversity of lakesites, each of which displays a unique subset of the potential lakeshore vegetation types.
