This rare, open woodland association is currently documented only from Capitol Reef National Park in southeastern Utah; this summary is derived from plots sampled in the park in 2003 and 2004. It is restricted to eolian deposits on benches and valley floors on sites that slope gently (5-15%), occur between 2067 and 2298 m elevation, and are oriented to southeastern aspects. Sand and litter cover most of the unvegetated surface, although biological soil crusts provide up to 40% cover. Parent materials include Wingate and Navajo sandstone eroded and redeposited as eolian sands. Soils are rapidly drained sands, sandy loams, and loamy sands. Total vegetation cover generally does not exceed 50% and is characterized by an open canopy, typically 2-10 m tall, of <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> that range in cover from 15 to 40%, and an understory dominated by <i>Opuntia fragilis</i> that ranges in cover from 15 to 55%. Associated shrubs include <i>Picrothamnus desertorum (= Artemisia spinescens)</i> and <i>Ericameria nauseosa</i>. The herbaceous layer is diverse in terms of species composition and provides sparse to moderate cover. Common graminoids include <i>Achnatherum hymenoides, Bouteloua gracilis</i>, and <i>Muhlenbergia pungens</i>. Forbs typically provide less than 1% total cover per species. |

This shrubland occurs in uplands on hilltops and residual dunes with diatomaceous soils derived from sand or shale between 400-1000 m elevation. <i>Cleome isomeris (= Isomeris arborea), Ephedra californica, Eriogonum fasciculatum</i>, and <i>Ericameria linearifolia</i> are conspicuous shrubs in the canopy. <i>Isocoma acradenia, Eriogonum gracillimum</i>, and <i>Eastwoodia elegans</i> are also present. Shrubs are <3 m tall, and the canopy is open. The ground layer is grassy. |

This woodland association has only been described from Capitol Reef National Park in southern Utah and may be confined to the immediate area because of the narrow suite of sensitive herbaceous species that defines the community. This summary is derived from plot data collected in the park in 1987 and 1988. The association occurs on high slopes; sites slope gently to the north between 2073 and 2195 m elevation. Parent materials include a variety of sedimentary rocks, giving rise to coarse-textured, rapidly drained soils that often have a surface cap of fine gravel. Total vegetation cover rarely exceeds 50%. The <i>Pinus edulis</i> and <i>Juniperus osteosperma</i> canopy ranges between 15 and 35% cover. <i>Juniperus osteosperma</i> is absent from one stand. The understory is often technically sparse in cover; there is no developed shrub layer, but there are generally scattered individuals of <i>Artemisia bigelovii, Eriogonum microthecum, Gutierrezia sarothrae, Opuntia polyacantha</i>, and <i>Shepherdia rotundifolia</i> present. The herbaceous layer is diverse in terms of species composition but provides sparse to low cover. Forbs, particularly sensitive cushion plants, define this community and include <i>Arenaria eastwoodiae, Enceliopsis nudicaulis, Erigeron compactus, Erigeron pumilus, Eriogonum alatum, Frasera albomarginata, Heterotheca villosa, Hymenopappus filifolius, Paronychia sessiliflora, Polygala subspinosa, Stenotus armerioides, Tetraneuris acaulis, Tetraneuris torreyana (= Tetraneuris depressa), Townsendia aprica</i>, and <i>Townsendia incana</i>. Graminoids include occasional tufts of <i>Achnatherum hymenoides</i> and <i>Aristida purpurea</i>. |
