Name: Pseudotsuga menziesii - Pinus contorta Central Rocky Mountain Forest Alliance Reference: NatureServe Biotics 2019 Description: Most occurrences of this montane coniferous forest alliance are dominated by a mix of <i>Pseudotsuga menziesii</i> and <i>Pinus contorta</i> (but there can be stands without the latter) and sometimes with other species, including <i>Pinus ponderosa, Pinus monticola</i>, and <i>Larix occidentalis</i>. The understory is often dominated by graminoids, such as <i>Calamagrostis rubescens, Carex geyeri, Carex rossii</i>, and <i>Pseudoroegneria spicata</i>. On mesic sites, a variety of shrubs such as <i>Acer glabrum, Juniperus communis, Physocarpus malvaceus, Symphoricarpos albus, Spiraea betulifolia</i>, or <i>Vaccinium membranaceum</i> may from a layer. This alliance is found in the interior Pacific Northwest, from southernmost interior British Columbia, eastern Washington, eastern Oregon, northern Idaho, western and northern Montana, and south along the east slope of the Cascades in Washington and Oregon. It is associated with a submesic climate regime with annual precipitation ranging from 50 to 100 cm, with a maximum in winter or late spring. Winter snowpacks typically melt off in early spring at lower elevations. Elevations range from 460 to 2400 m (1500-7900 feet). Stands occur on cool, dry sites on mid to upper slopes, steep slopes, ridgelines, rocky sites and benches on all aspects.  Accession Code: urn:lsid:vegbank.org:commConcept:38683-{AA5CE6BE-2D94-457F-A078-501A9688AAA3} Plot-observations of this Community Concept: 0
