Name: Abies concolor - (Pseudotsuga menziesii) / Jamesia americana - Holodiscus dumosus Scree Woodland Reference: NatureServe Biotics 2019 Description: This white fir woodland association occurs in the southern Rocky Mountains in southern Colorado, New Mexico and Arizona at elevations between 2370 and 2900 m (7780-9250 feet). Stands are found on moderately steep to very steep (45-85%) colluvial slopes that may occur on any aspect, but they are often found on cool northerly aspects. Soils are shallow, poorly developed and rocky loams or clay loams, often with surfaces covered with talus and scree. Soils can be saturated (seeps) and range from somewhat poorly drained to rapidly drained. Cover of litter and duff, wood and moss is often moderate to high, but not as high as rock and gravel. The vegetation is characterized by a very open (10%) tree canopy on steep scree fields to a moderately closed canopy on sheltered canyon slopes (up to 75% cover). The overstory is dominated by <i>Abies concolor</i> with <i>Pseudotsuga menziesii</i> as the common codominant or subdominant. Other conifers, such as several species of <i>Pinus</i> and <i>Juniperus scopulorum</i>, may be present in the canopy. <i>Populus tremuloides</i> can be well-represented in the canopy. The understory is a mixture of mesic tall shrubs that are well-represented to abundant and typically dominated by <i>Jamesia americana</i> and/or <i>Holodiscus dumosus</i>. <i>Physocarpus monogynus</i> can also codominate some stands. Other frequent shrubs may include <i>Ribes</i> spp., <i>Robinia neomexicana, Rubus idaeus</i>, and <i>Symphoricarpos</i> spp. The herbaceous layer is typically low in cover and diversity. <i>Saxifraga bronchialis ssp. austromontana</i> is a common forb. Where shrub cover is lower, graminoids such as <i>Carex rossii, Carex inops ssp. heliophila</i>, and <i>Koeleria macrantha</i> may be more prevalent.  Accession Code: urn:lsid:vegbank.org:commConcept:29799-{FB3BDC46-56D4-432E-AA51-0B1CB455FC4C} Plot-observations of this Community Concept: 0
