Comm #5161	A.1110 » more details accession code: VB.CC.884.A1110 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This dwarf-shrubland alliance occurs in western Colorado and eastern Utah, Wyoming and Montana on mesas, plateaus, plains, low hills and eroded 'badlands.' Sites are nearly flat to moderately steep with moderately deep to deep, usually saline, alkaline soils. Soils are typically fine-textured and often have high erosion rates because of poor infiltration and high runoff. The soil surface is often mostly barren. Stands have a very sparse to moderately dense cover of dwarf-shrubs that is dominated by ~Atriplex gardneri$. ~Picrothamnus desertorum (= Artemisia spinescens)$ and ~Artemisia tridentata$ are codominants in some stands. Other shrubs and dwarf-shrubs may include ~Atriplex$ spp., ~Krascheninnikovia lanata, Sarcobatus vermiculatus, Suaeda$ spp., and ~Tetradymia spinosa$. The herbaceous layer, if present, may be dominated by graminoids or forbs. Common species include ~Pleuraphis jamesii (= Hilaria jamesii), Leymus salinus, Achnatherum hymenoides (= Oryzopsis hymenoides), Pascopyrum smithii, Eriogonum pauciflorum, Xylorhiza venusta$, or ~Monolepis nuttalliana$. Diagnostic of this dwarf-shrubland alliance is the dominance or codominance of ~Atriplex gardneri$.
Comm #5162	Ephedra viridis / Bouteloua gracilis Shrubland » more details accession code: VB.CC.31882.CEGL003934	Western Ecology Working Group of...	0	This association is currently known only from Glen Canyon National Recreation Area in southeastern Utah. This descriptive information is from there, and it does not seem to be particularly common. It is found on plateaus at elevations between 1825 and 1982 m. Soils are rapidly drained loamy sands or sandy loams derived from eolian deposits. Vegetation is characterized by relatively open shrublands dominated by <i>Ephedra viridis</i> with <i>Gutierrezia sarothrae</i> and <i>Opuntia erinacea</i> as the only consistently associated shrubs. The understory is dominated by <i>Bouteloua gracilis</i>. Other graminoids include <i>Achnatherum hymenoides, Vulpia octoflora (= Festuca octoflora), Bromus tectorum</i>, and <i>Sporobolus cryptandrus</i>. Forbs commonly present with sparse cover include <i>Eriogonum cernuum, Lupinus pusillus</i>, and <i>Sphaeralcea parvifolia</i>.

Comm #5165	Typha domingensis - Pontederia cordata Herbaceous Vegetation » more details accession code: VB.CC.36539.CEGL003988	Hilsenbeck, C. E., R. H. Hofstet...	0	This <i>Typha domingensis</i>-dominated community occurs in disturbed portions of wet prairie or marsh landscapes of southern Florida. These areas are typically sites with altered hydrological, soil, or nutrient conditions, most commonly developing in canals, road ditches, levees, and other artificial drainage features. The type has a wide hydrological amplitude tolerating inundation for as little as 3 months or as long as 10 months. Relatively few other species are associated with this community.

Comm #5167	A.1026 » more details accession code: VB.CC.798.A1026 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	This alliance includes tidal areas in upper marsh edges and flats dominated by ~Borrichia frutescens$. It occurs at spatial scales ranging from narrow bands to flats in excess of 500 ha; it often occurs either just below ~Iva frutescens$ or ~Baccharis halimifolia$, or just above ~Juncus roemerianus$ or ~Spartina alterniflora$. Other characteristic species include ~Spartina patens, Iva frutescens ssp. frutescens, Iva frutescens ssp. oraria$, and ~Limonium carolinianum$. In Texas, the composition of this low-diversity, irregularly tidally flooded shrubland is variable and can include ~Spartina spartinae, Sporobolus virginicus, Monanthochloe littoralis, Sarcocornia perennis, Limonium carolinianum, Lycium carolinianum var. quadrifidum, Rayjacksonia phyllocephala$, and ~Batis maritima$. Here, these communities often occur just above the lower tidal flat communities ~~Batis maritima - Sarcocornia perennis$ Dwarf-shrubland (CEGL003956)$$ or ~~Sarcocornia perennis - Batis maritima - Distichlis spicata$ Dwarf-shrubland (CEGL002278)$$.
Comm #5168	Typha latifolia Seasonally Flooded Herbaceous Alliance » more details accession code: VB.CC.18807.TYPHALATIFOLIAS	Southeastern Ecology Working Gro...	0	Seasonally flooded Typha latifolia marshes occurring in depressional wetlands, including peat soils of seasonally flooded depressions in the Coastal Plain of Florida. Pontederia cordata may codominate. In these areas, surface water is present for extended periods during the growing season, but is absent by the end of the growing season in most years.

Comm #5170	A.1202 » more details accession code: VB.CC.973.A1202 NOT CURRENTLY ACCEPTED	EcoArt 2002	0	These grasslands occur on valley bottoms, lower alluvial slopes, coastal bluffs and terraces along the central coast of California north to Washington. Elevations range from 0-300 m. Climate is maritime with most of the annual precipitation occurring as rain during the winter. Stands require seasonally or permanently saturated soils with a shallow water table within the cool, moist band within 10 km of the coast. Soils are moderately deep (120 cm), with a high organic component (23%) and a thick litter layer (8 cm). Soil texture is loam with a pH of 6. Stands form a mosaic with forest and scrub in the coastal prairies and generally occur on moderate slopes (24% slope) with southern aspects. Stands on open bluffs tolerate the high winds and salt spray well. This vegetation has a moderately dense (50-60% cover) herbaceous layer (<1.5 m tall) that is dominated by the cool-season sod-grass ~Calamagrostis nutkaensis$. ~Elymus glaucus$ and ~Festuca rubra$ are common graminoid associates. Perennial forbs may be diverse, but rarely contribute much cover. Associates may include ~Symphyotrichum chilense (= Aster chilensis), Carex obnupta, Lolium arundinaceum (= Festuca arundinacea), Pteridium aquilinum, Iris tenax, Maianthemum dilatatum, Marah oreganus, Achillea millefolium, Rubus ursinus, Artemisia suksdorfii, Heracleum maximum (= Heracleum lanatum), Holcus lanatus$, or ~Anthoxanthum odoratum$. Occasional emergent shrubs, such as ~Vaccinium ovatum$, and trees, such as ~Picea sitchensis$, may be present. Exotic species, such as ~Poa pratensis$ and ~Dactylis glomerata$, may be abundant. Adjacent vegetation may include ~Holcus lanatus / Anthoxanthum odoratum$ and ~Fragaria chiloensis / Armeria maritima$ communities, and various scrub and forest types.
