Name: Tsuga mertensiana / Sparse Understory Forest Reference: Western Ecology Working Group of... Description: Stands of this forest are found throughout the Sierra Nevada, however, predominantly north of the Kings River. This association is found at mid to high elevations (2255-2990 m [7400-9800 feet]) on gentle to somewhat steep (2-29%) slopes. Aspect varies but is often on northeast-facing slopes. Microrelief is usually broken and hummocky. Sites are found at lower to upper portions of slopes and rarely, are on ridgetops. Soils are typically from granitic parent material, however, some stands to the north are derived from volcanic or mixed lithology. These soils are typically greater that 63.5 cm (25 inches) and occasionally greater than 89 cm (35 inches). Very little bare soil is usually exposed. Soil depths range from 35-100 cm (14-40 inches). Soil textures range from sand to loam and are excessively drained to well drained. Stands form a dense forest with an open understory. The tree layer is dominated by <i>Tsuga mertensiana</i> mixed with <i>Abies magnifica</i>. <i>Pinus contorta var. murrayana</i> and <i>Pinus monticola</i> are also important overstory tree species. The understory layers are typically open. Occasional shrub species may include <i>Ribes roezlii (= Grossularia roezlii)</i> and <i>Ribes montigenum</i>. Herb species may include <i>Eucephalus breweri (= Chrysopsis breweri), Hieracium albiflorum, Poa bolanderi</i>, and <i>Carex rossii</i>. Conifer regeneration is high at this association and is dominated by <i>Abies magnifica</i> with significantly lower amounts of <i>Tsuga mertensiana</i>.  Accession Code: VB.CC.32358.CEGL008685 Plot-observations of this Community Concept: 0
