click to update datacart
Name: Abies magnifica - Abies lowiana / Sparse Understory Forest Reference: NatureServe Biotics 2019 Description: This forest type is widespread in the central and southern Sierra Nevada, California, at middle to lower elevations, generally ranging from 1983 to 2684 m (6500-8800 feet). Aspects are variable, but northeast to northwest slopes are common, and average solar radiation levels are among the lowest in the region. Slopes are gentle to steep. Stands occur on all slope positions. Sites have significantly less bare ground and surface gravel and a deeper litter layer than other sites. Soils are usually formed in place on granitic bedrock. In general, soils are deeper than most other sites and are typically well-drained sandy. The average water-holding capacity is one of the highest in the upper montane of the Sierra Nevada. Stands in this association are dense, multi-layered forests with somewhat open overstories distinguished by the presence of <i>Abies lowiana</i> in a mix with <i>Abies magnifica</i>; together these species dominate the stands. Understory shrub cover is significantly lower than other associations in late-seral stands. <i>Symphoricarpos acutus, Chrysolepis sempervirens</i>, and <i>Ribes roezlii</i> are the most common shrubs, but none are frequent. Herb cover is also low, and while no species are frequent, the most common ones are <i>Pyrola picta, Hieracium albiflorum</i>, and <i>Corallorhiza maculata</i>. <i>Abies magnifica</i> is the dominant regenerating conifer. This association is often adjacent to or interspersed with ~<i>Abies magnifica - Abies lowiana - Pinus lambertiana</i> / Sparse Understory Forest (CEGL008683)$$ and ~<i>Abies magnifica - Abies lowiana - Pinus jeffreyi</i> Sierran Montane Chaparral Forest (CEGL008682)$$ on mesic sites.  Accession Code: urn:lsid:vegbank.org:commConcept:36720-{119216F2-4D28-4F95-ADFC-86FAD6E757B6} Plot-observations of this Community Concept: 0
