Name: Spiraea splendens / Penstemon newberryi - Streptanthus tortuosus Sparse Vegetation Reference: NatureServe Biotics 2019 Description: This sparse vegetation 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 sparse alpine association grows in cracks between granite slabs on poorly developed, sandy soils. Slopes are moderate to steep, and stands prefer mid to upper slope positions. Aspects are southeast to northwest. This sparse alpine and subalpine vegetation grows in cracks of granitic slabs in rapidly drained soils. The canopy is open and between 0.5-1 m in height. Emergent individuals of <i>Pinus contorta var. murrayana</i> may be present. Forb and graminoid species are highly variable, but <i>Spiraea splendens var. splendens</i> is generally present. The graminoid <i>Elymus elymoides</i> may be common in some stands. Other graminoid associates may include <i>Juncus parryi, Agrostis variabilis</i>, and/or <i>Carex rossii</i>. The diagnostic forb <i>Penstemon newberryi</i> is usually present in small amounts. Other forbs present at trace amounts may include <i>Sedum obtusatum, Perideridia parishii</i>, and/or <i>Selaginella watsonii</i>.  Accession Code: urn:lsid:vegbank.org:commConcept:32369-{6D97592C-3927-4635-8A51-ED8C84481757} Plot-observations of this Community Concept: 0
