CEGL002380 Pinus longaeva Woodland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Great Basin Bristlecone Pine Woodland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: 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 (1-21° 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 Pinus longaeva trees that range in cover from 15 to 25%. The associated canopy tree layer is diverse, provides sparse to low cover, and includes Juniperus osteosperma, Juniperus scopulorum, Pinus edulis, Abies concolor, Abies lasiocarpa, Picea engelmannii, Picea pungens, Pinus flexilis, and Pseudotsuga menziesii. 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 Acer glabrum, Amelanchier utahensis, Arctostaphylos patula, Ericameria nauseosa, Eriogonum corymbosum, Juniperus communis, Mahonia repens, Purshia tridentata, and Shepherdia canadensis. The herbaceous layer is diverse but rarely provides cover exceeding 5%. Graminoids are low in diversity and provide sparse cover, although Leymus salinus cover may exceed 1%. Forbs are moderate to high in diversity but provide sparse cover, typically less than 1%. The most abundant forbs are Oxytropis oreophila and Tetraneuris acaulis.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is known only from Capitol Reef National Monument. Until other data become available, there is no global information. There are few examples of community data from Pinus longaeva stands; as more data become available, we expect to be able to identify several types of intermountain bristlecone woodland.

Floristics: Total vegetation cover is sparse to moderate and is often a mix of conifer species, but it is always characterized by the canopy tree Pinus longaeva that ranges in height from 5-20 m, has dbh ranging from 12-106 cm, and provides <1-22% cover. Associated canopy trees range from 5-10 m tall and include Abies concolor, Abies lasiocarpa, Picea engelmannii, Picea pungens, Pinus edulis, Pinus flexilis, and Pseudotsuga menziesii that have a range of dbh from 12-118 cm and contribute sparse to low cover. Shrubs are often absent from most stands and provide only sparse cover when present; they include Acer glabrum, Amelanchier utahensis, Arctostaphylos patula, Cercocarpus montanus, Juniperus communis, Gutierrezia sarothrae, Purshia tridentata, Shepherdia canadensis, and Mahonia repens. The herbaceous layer is moderate to high in terms of floristic diversity and contributes sparse to low cover. Common graminoids include Bromus anomalus, Carex rossii, Leymus salinus, and Elymus elymoides. Forbs that contribute low cover include Astragalus kentrophyta, Cirsium wheeleri, Solidago velutina, Eriogonum panguicense, and Stenotus armerioides (= Haplopappus armerioides).
Dynamics: This association is known only from Capitol Reef National Monument. Until other data become available, there is no global information.
Environmental Description: This sparse woodland occurs on plateau rims, ridge crests, hills, canyonsides, badlands breaks, colluvial slopes, interfluves, and valley slopes. Sites are flat to steep (0-39° slopes), occur between 2170 and 3311 m in elevation, and are oriented to all aspects. The ground surface has sparse to high cover of litter and duff, sparse to high cover of large and small rocks, low to high exposure of bare soil, and sparse to low cover of downed wood. Litter depths range from 0-5.7 cm. Soils are moderately well-drained to rapidly drained sandy clays, sandy clay loams, silt clay loams, and clays derived from local shale formations.
Geographic Range: This association is known only from Capitol Reef, Bryce Canyon and Cedar Breaks national parks in southern Utah.
