Name: Abies magnifica - Abies lowiana - Pinus lambertiana / Sparse Understory Forest Reference: NatureServe Biotics 2019 Description: This forest is widespread at lower elevations on the west side of the upper montane of the central and southern Sierra Nevada, California. Elevations generally lie between 1770 and 2410 m (5800-7900 feet) in elevation, but typically below 2288 m (7500 feet). Aspects are variable. Stands are usually on middle and lower slopes. Sites have significantly less surface gravel and a deeper litter layer than most other types. Soils are usually formed in place on granitic bedrock, but some form on colluvium or glacial till. In general, soils are deep and typically well-drained sandy loams or loams, rarely sands. The average water-holding capacity is generally moderate. Stands in this association are dense multi-layered forests with a moderate cover of understory shrubs and herbs. A mix of several species with <i>Abies magnifica</i> distinguishes the overstory, but <i>Abies lowiana</i> and <i>Abies magnifica</i> generally dominate. <i>Pinus lambertiana</i> is characteristically present, but it occurs as widely scattered predominants. <i>Pinus jeffreyi</i> and <i>Calocedrus decurrens</i> are occasional members of these stands. Shrubs typically occur in patches or as individuals. <i>Chrysolepis sempervirens</i> is the most common shrub; other shrubs may include <i>Symphoricarpos acutus</i> or <i>Ribes roezlii</i>. Herb cover averages 74%, but no single species is frequent or provides significant cover. <i>Pyrola picta, Kelloggia galioides, Hieracium albiflorum</i>, and <i>Pteridium aquilinum</i> are the most commonly encountered species. These stands are often adjacent to and interspersed with ~<i>Abies magnifica - Abies lowiana</i> / Sparse Understory Forest (CEGL008681)$$ and ~<i>Abies magnifica - Abies lowiana - Pinus jeffreyi</i> Sierran Montane Chaparral Forest (CEGL008682)$$ on mesic sites.  Accession Code: urn:lsid:vegbank.org:commConcept:36722-{ACB2F542-E660-4587-A122-E9905ECFCDBD} Plot-observations of this Community Concept: 0
