Name: Pinus flexilis / Symphoricarpos oreophilus Woodland
Reference: NatureServe Biotics 2019
Description: This limber pine woodland is only known from Fossil Butte National Monument in southwestern Wyoming. Stands occur at higher elevations in the northern portion of the monument. It occupies high slopes and rims of ridges and a drainage. The sites are moderate to steep (5-38°), north- or northwest-facing slopes between 2222 and 2416 m elevation. The unvegetated surface has low exposure of bare soil, high cover of litter, low cover of small rocks, and sparse cover of large rocks. Downed wood has up to 10% cover. The parent materials include the Fossil Butte and Angelo members of the Wasatch Formation and the main body of the Wasatch Formation. Soils are rapidly drained and texturally are sandy clay loam or clay loam. This association is characterized by an open to dense canopy, typically 10-15 m tall, of the tree <i>Pinus flexilis</i> that ranges in cover from 10-55%, and an understory of the short shrub <i>Symphoricarpos oreophilus</i> that ranges in cover from less than 10-30%. The total vegetation cover ranges from 30-99% in these moderately to densely vegetated stands. Sapling <i>Pinus flexilis</i> and <i>Pseudotsuga menziesii</i>, typically 2-5 m tall, provide sparse subcanopy cover. The shrub layer is diverse and includes low cover of tall, short, and dwarf-shrubs such as <i>Amelanchier utahensis, Artemisia tridentata ssp. vaseyana, Cercocarpus montanus, Mahonia repens, Ribes cereum, Rosa woodsii</i>, and <i>Shepherdia canadensis</i>. The herbaceous layer is low in terms of diversity and provides sparse to low cover. Common grasses include <i>Poa pratensis, Poa fendleriana</i>, and <i>Leymus cinereus</i>. Forbs include <i>Achillea millefolium, Delphinium nuttallianum, Lappula occidentalis, Lithospermum ruderale, Mertensia oblongifolia</i>, and <i>Pteryxia terebinthina</i>. <i>Pinus flexilis</i> and <i>Pseudotsuga menziesii</i> seedlings provides sparse cover in some stands.
