Name: Pinus contorta / Carex rossii Forest
Reference: NatureServe Biotics 2019
Description: This association is found mainly between 2155 and 2956 m (7070-9700 feet) elevation in Teton National Park, Yellowstone National Park, the Wind River Mountains, and the Medicine Bow Mountains of northwestern and southeastern Wyoming, and in the north-central Uintah Mountains of northern Utah. This forest occupies gentle slopes on cold sites that are very well-drained. Soils are primarily derived from quartzite parent materials and are gravelly sandy loams to gravelly loams. The overstory canopy is almost exclusively <i>Pinus contorta</i> (30-64%). Small amounts of <i>Picea engelmannii, Abies lasiocarpa</i>, and <i>Pinus albicaulis</i> may be present. Shrubs may be completely absent or present in trace amounts and include species such as <i>Arctostaphylos uva-ursi, Vaccinium cespitosum, Vaccinium scoparium</i>, and <i>Mahonia repens</i>. The herbaceous understory is very depauperate, with <i>Lupinus argenteus, Solidago multiradiata, Sedum lanceolatum, Orthilia secunda</i>, and <i>Pyrola chlorantha</i> present. <i>Poa nervosa, Carex geyeri</i>, and <i>Carex rossii</i> are also common. <i>Carex rossii</i> is the only species to have the highest cover (1-10%) in all stands (100% constancy) and can obtain dominance because all other herbaceous species are sparse. This association is differentiated from similar associations by the clear dominance of <i>Pinus contorta</i> in the overstory canopy.
