Comm #11884	Coastal Plain Acidic Cliff Sparse Vegetation » more details accession code: VB.CC.34844.CEGL004388	Southeastern Ecology Working Gro...	0	This sparsely vegetated cliff association occurs in the Coastal Plain of the southeastern United States. Examples are found on steep to vertical outcrops of acidic unconsolidated sediments, generally on river bluffs. Vegetation is sparse, consisting of scattered trees, shrubs, herbs, and sometimes bryophytes that include weedy species, species of the adjacent forest communities, along with species of open dry and open wet habitats. <i>Pinus taeda, Morella cerifera</i>, and <i>Andropogon</i> spp. are frequent. Most of the species are acid-tolerant, and more basophilic species are largely absent.
Comm #11885	Salix exigua / Elymus x pseudorepens Shrubland » more details accession code: VB.CC.32266.CEGL001198	Western Ecology Working Group of...	0	This is a lowland riparian shrubland association known from the middle and upper Rio Grande watershed in north-central New Mexico. This type is associated with low-gradient rivers at elevations around 1830 m (6000 feet). Stands occur on depositional sidebars or island bars that are frequently flooded (annually). Soils have been reported as loamy and sandy-skeletal Aeric Fluvaquents that are normally wet within 0.5 m of the surface. This association is characterized by moderate to dense canopies of <i>Salix exigua</i>. The understory is grassy and dominated by abundant <i>Elymus x pseudorepens</i>. An additional nine wetland indicators have been recorded for the type: <i>Carex pellita (= Carex lanuginosa), Muhlenbergia racemosa, Argentina anserina, Boehmeria cylindrica, Equisetum arvense, Equisetum laevigatum, Lycopus asper, Oenothera elata ssp. hirsutissima</i>, and <i>Rumex verticillatus</i>.

Comm #11887	Artemisia arbuscula ssp. arbuscula / Leymus salinus ssp. salmonis Shrub Herbaceous Vegetation » more details accession code: VB.CC.34644.CEGL001410	Western Ecology Working Group of...	0	The plant association is reported from the southern end of the Lemhi Range, Idaho, within the Beaverhead Mountains ecoregional section. The plant association occurs within a region of cool, arid climatic conditions. The average annual precipitation is 25.4-30.5 cm (10-12 inches). The association occurs in lower slope positions, on relatively steep, northwest-facing slopes, at 1585 to 8130 m (5200-6000 feet) elevation, on limestone parent materials. Soils are poorly developed, thin and rocky. Little information is available regarding the structure and composition of this association. The dwarf-shrub vegetation is dominated by <i>Artemisia arbuscula</i>. <i>Pseudoroegneria spicata</i> and <i>Leymus salinus ssp. salmonis</i> are codominant in the herbaceous layer and usually abundant, often exceeding 50% cover. No additional information is available on the species composition of the dwarf-shrub plant association.

Comm #11889	Salix geyeriana / Mesic Graminoids Shrubland » more details accession code: VB.CC.32585.CEGL001210	Western Ecology Working Group of...	0	This is an important association in Idaho, Oregon, Montana, Utah, Colorado, and northwestern Wyoming. Stands of this association are often found in wide mountain valleys, cirques, and troughs, at elevations from about 1525 to 2745 m (5000-9000 feet) with narrow, meandering streams or braided rivers. The association mainly occurs on seasonally saturated or flooded sites such as streambanks, terraces, floodplains, abandoned meanders, spring-fed meadows, lake or reservoir shores, and occasionally alluvial gravel bars. Soils vary but are mostly silt to clay loams with organic/sedge peat horizons. An open canopy of tall, clumped <i>Salix geyeriana</i>, with occasionally intermixed <i>Salix boothii</i> (with <20% cover), characterizes this association. Other shrubs, including <i>Dasiphora fruticosa ssp. floribunda, Ribes</i> spp., <i>Rosa woodsii</i>, and low <i>Salix</i> spp., are scattered around the bases of taller <i>Salix</i> clumps. The herbaceous understory is dominated by a diverse mix of mesic graminoid species that always has greater total cover than the total cover of mesic forbs. In good-condition, mid- to late-seral stands, the most common graminoids are <i>Carex microptera, Carex pellita, Deschampsia caespitosa</i>, and occasionally <i>Carex nebrascensis</i>, but no single species consistently has high cover. Other graminoids with moderate cover and constancy include <i>Calamagrostis canadensis, Carex aquatilis, Carex praegracilis, Carex rostrata, Carex utriculata, Glyceria</i> spp., and <i>Juncus balticus</i>. <i>Poa pratensis</i> is present in nearly all stands, but its cover varies depending on the amount of grazing disturbance and site desiccation. Stands in poor condition need to be codominated by a mixture of native graminoids (not a single species such as <i>Deschampsia caespitosa</i>) with the introduced graminoids and forbs. The most common forb species are sometimes indicative of grazing disturbance (e.g., <i>Achillea millefolium, Geum macrophyllum, Iris missouriensis, Maianthemum stellatum, Potentilla gracilis, Thalictrum</i> spp., <i>Taraxacum officinale</i>, and <i>Trifolium</i> spp.).

Thrinax radiata, Casasia clusiifolia, and Erithalis fruticosa are characteristic canopy components.
