Name: Carex filifolia - Penstemon heterodoxus Herbaceous Vegetation Reference: Western Ecology Working Group of... Description: This herbaceous association is currently only known from Yosemite National Park in California, and the following description is based on occurrences there. Additional information will be added as it becomes available. This alpine grassland prefers open, rocky, dry habitats between 3050 and 3350 m (10,000-11,000 feet) of elevation. Aspects are generally south and west. Stands often grow on the upper margins of meadows, or just beyond the zone of seasonal soil saturation if the stand is adjacent to a lake. Soils are well-drained sands or loams. Stands of this highly diverse and open alpine grassland occur on dry sites at the upper edges of meadows. Most stands occur as patches between rock outcrops or intergrade into <i>Pinus contorta var. murrayana</i> or <i>Pinus albicaulis</i> woodlands. <i>Carex</i> sp. (<i>Carex exserta, Carex filifolia</i>) dominates the stands with 20% cover. Ninety species have been recorded in stands of this association, though none contribute much cover. The forb <i>Penstemon heterodoxus</i> is diagnostic, but only averages trace cover. Common graminoid associates include <i>Achnatherum nelsonii, Juncus parryi, Carex filifolia, Poa wheeleri, Poa stebbinsii, Trisetum spicatum</i>, and/or <i>Elymus elymoides</i>. Forb associates may include <i>Eriogonum incanum, Saxifraga aprica, Cistanthe umbellata, Gayophytum humile, Lupinus lepidus, Phlox diffusa, Phyllodoce breweri, Minuartia rubella</i>, and/or <i>Rumex paucifolius</i>.  Accession Code: VB.CC.34499.CEGL008662 Plot-observations of this Community Concept: 0
