CEGL003160 Ptilagrostis kingii Wet Meadow
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Sierra False Needlegrass Wet Meadow
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This false needlegrass association is known from the glaciated highlands of the central and southern Sierra Nevada. It is subalpine to alpine and ranges from 3000 to 3350 m (8500-11,000 feet) elevation. Sites are seasonally saturated meadows formed along permanent streams as stringer meadows. Some sites occur in basins. This type is often found along small first- to second-order streams. However, more frequently stands are some distance from streams in elevated portions of meadows. Surfaces may be hummocky or linear. This association averages a total vegetative cover of close to 100%. Trees are usually absent and shrubs are sparse. The only shrub of any cover is the subshrub Vaccinium cespitosum. Ptilagrostis kingii is the dominant, followed by Carex subnigricans, Danthonia intermedia, Carex pachystachya, and Luzula orestera. Forbs include Antennaria sp., Oreostemma alpigenum, and several other species below 50% constancy.
