Name: Carex spectabilis Subalpine Meadow Alliance Reference: NatureServe Biotics 2019 Description: These are lush herbaceous communities with a mix of forbs and graminoids, either of which may be dominant or codominant. <i>Carex spectabilis</i> is usually the dominant graminoid species in terms of cover and constancy. The most constant dominant or codominant forbs include <i>Arnica x diversifolia, Lupinus arcticus ssp. subalpinus, Pedicularis contorta, Phlox diffusa ssp. longistylis, Polygonum bistortoides, Potentilla flabellifolia</i>, and <i>Sibbaldia procumbens</i>. These vegetation types are typically located at or slightly below the upper treeline in high mountains primarily of the Olympic Mountains and Cascade Range, although some associations extend to the Sierra Nevada and northern Rocky Mountains. They are often found in association with subalpine parkland. The climate is cold and snowy with annual precipitation exceeding 150 cm and a short growing season. Elevations typically range from 1000-24000 m. These communities occur on well-drained, moderately steep to steep slopes which are clear of snow by early summer. Soils are composed of varied parent materials, but are usually young and poorly developed. This alliance often forms part of a subalpine parkland mosaic just below upper treeline.
