Pinus longaeva Woodland
Reference:
Western Ecology Working Group of...
Description:
This rare woodland association is known from Capitol Reef, Bryce Canyon and Cedar Breaks national parks in southern Utah. Small stands of this woodland occur on high slopes of scree or talus. Sites are gentle to moderately steep (1- to 21-degree slopes), occur between 2480 and 3311 m elevation, and are oriented to all aspects. The unvegetated surface has moderate cover of litter, low to moderate cover of rocks and gravel, and low exposure of bare soil. Parent materials are Carmel Formation shale and Claron Formation shale. Soils are rapidly drained and texturally are sandy loam. Total vegetation cover ranges from 27 to 65%. The association is characterized by an open canopy, typically 10-15 m tall, of <i>Pinus longaeva</i> trees that range in cover from 15 to 25%. The associated canopy tree layer is diverse, provides sparse to low cover, and includes <i>Juniperus osteosperma, Juniperus scopulorum, Pinus edulis, Abies concolor, Abies lasiocarpa, Picea engelmannii, Picea pungens, Pinus flexilis</i>, and <i>Pseudotsuga menziesii</i>. The shrub layer is diverse and provides sparse to low cover with no one shrub consistently present. Shrubs that occasionally provide low cover within stands include <i>Acer glabrum, Amelanchier utahensis, Arctostaphylos patula, Ericameria nauseosa, Eriogonum corymbosum, Juniperus communis, Mahonia repens, Purshia tridentata</i>, and <i>Shepherdia canadensis</i>. The herbaceous layer is diverse but rarely provides cover exceeding 5%. Graminoids are low in diversity and provide sparse cover, although <i>Leymus salinus</i> cover may exceed 1%. Forbs are moderate to high in diversity but provide sparse cover, typically less than 1%. The most abundant forbs are <i>Oxytropis oreophila</i> and <i>Tetraneuris acaulis</i>.
