Name: Tsuga mertensiana - Pinus monticola Forest Reference: NatureServe Biotics 2019 Description: This association is found throughout the northern regions of the Sierra Nevada, predominantly north of the Kings River, occurring more commonly in the northern portions of this range. Stands are usually less than 10 acres in size. They are found at mid to high elevations (2170-2865 m [7120-9400 feet]) on somewhat steep to steep (30-60%) broken and hummocky slopes. Aspects range from northeast to northwest, and snow pack typically lingers into the summer. This association is usually found on the upper portions of slopes just below ridgetops. Soils are moderately deep to deep (56-100+ cm [22-40+ inches]) often greater than 100 cm. Soil texture varies between gravelly sands, gravelly sandy loams, and gravelly loams above sands and sandy loams. Soils are usually excessively drained due to coarse textures. Parent material is granitic or volcanic (including pumice) but rarely metamorphic. Stands form moderately dense forests dominated by <i>Tsuga mertensiana</i>. <i>Pinus albicaulis</i> and <i>Abies magnifica</i> are also significant. <i>Pinus contorta</i> occasionally contributes to minor cover. The shrub layer is essentially nonexistent. The understory herb layer is typically sparse and may include low amounts of <i>Arabis platysperma, Hieracium albiflorum, Pedicularis semibarbata, Phacelia hydrophylloides, Poa bolanderi, Poa secunda</i>, and <i>Carex</i> sp.  Accession Code: urn:lsid:vegbank.org:commConcept:36726-{B0B60FF6-6618-4BFF-A364-232526E89EAF} Plot-observations of this Community Concept: 0
