CEGL005415 Pinus aristata Krummholz
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Bristlecone Pine Krummholz
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This krummholz shrubland association is known from several locations in the Great Sand Dunes National Park and Preserve high in the Sangre de Cristo Range in southern Colorado and is likely more widespread in high mountains of southern Colorado and northern New Mexico. Stands occur on high slopes and ridges near upper treeline between 3605 and 3735 m (11,820-12,245 feet) elevation. Slopes are very steep and range from southeast-, southwest-, or west-facing slopes. Soils are rapidly drained loamy sands. Ground cover has high cover of gravel and rock. Vegetation is characterized by an open canopy of stunted Pinus aristata with 10-30% cover. Pinus flexilis may be present in some stands but does not dominate. A sparse short- or dwarf-shrub layer may include Dasiphora fruticosa ssp. floribunda, Ribes spp., or Salix brachycarpa. Herbaceous cover is variable (10-60% cover), depending on the amount of rock present, and includes both forbs and graminoids. Alpine herbaceous species are typically present, such as Aquilegia coerulea, Arenaria fendleri, Carex elynoides, Carex rupestris var. drummondiana, Cirsium scopulorum, Erigeron pinnatisectus, Eriogonum flavum, Festuca brachyphylla, Geum rossii var. turbinatum, Rhodiola integrifolia, Sedum lanceolatum, Selaginella densa, Tetraneuris acaulis, and Trifolium dasyphyllum.
