Name: Pinus edulis - Juniperus osteosperma / Quercus havardii var. tuckeri Woodland Reference: NatureServe Biotics 2019 Description: This woodland appears to be restricted to southeastern Utah. The open tree canopy of <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> is typically 2-5 m tall and ranges in cover from 10 to 50%. The understory is dominated by clumps of <i>Quercus havardii var. tuckeri</i> that range in cover from 5 to 65%. Associated shrubs vary depending on the aspect and the amount of soil moisture available. The herbaceous layer is more consistent in species composition yet provides only sparse cover. Common graminoids include <i>Achnatherum hymenoides, Bouteloua gracilis, Muhlenbergia pungens</i>, and <i>Pleuraphis jamesii</i>. Forbs often present include species typical of sandy sites such as <i>Cryptantha flava, Tetraneuris acaulis, Lepidium montanum</i>, and <i>Streptanthella longirostris</i>. Total vegetation cover ranges from 21% to more than 100%. Sites occur between 1445 and 1905 m (4740-6250 feet) in elevation. It appears to be limited to sites with deep accumulations of eolian and alluvial sands on canyon and valley floors, in intermittent washes, and on dunes and sandsheets on plateaus and benches, on any aspect. Bare soil and sand cover most of the unvegetated surface, and biological soil crusts can provide up to 30% cover. Geologic substrates include various sandstones, which for the most part have eroded and been redeposited as eolian sands. Soils are rapidly drained, deep loamy sands, sandy loams, and sands.  Accession Code: urn:lsid:vegbank.org:commConcept:31405-{EB3F3923-03C4-47EC-B688-0A89BCC148EA} Plot-observations of this Community Concept: 0
