Spartina foliosa Herbaceous Vegetation

This association is known from the Point Reyes National Seashore and from Suisun Marsh in California. Information about its global characteristics is not available without additional inventory. Other anecdotal observations in San Pablo Bay and San Francisco Bay suggest that it regularly occupies the outer edges of tidal mudflats in the areas with deepest tidal water. <i>Salicornia virginica</i> typically occupies the landward edges of the stands. This association is found on flat, linear/even basins/wetlands with no slope. It occurs on medium silt soil textures and silty alluvium parent material. Typically stands are monotypes with <i>Spartina foliosa</i> comprising most or all of the vegetative cover, occasionally with some minor cover of <i>Salicornia virginica</i> and algae. |

This riparian shrubland association is found east of the Cascade Mountains in eastern Oregon, generally on third or fourth order streams. Elevations range from 825 to 1495 m (2700-4900 feet). It occurs in narrow to wide valleys that are V-, trough- and flat-shaped and have moderate gradients and moderately steep to steep sideslopes. Fluvial surfaces are alluvial bars and streambanks, most with abundant bare ground, gravel or rock exposed on the soil surface. <i>Salix prolixa</i> forms a scattered to dense shrub overstory. <i>Rosa woodsii</i> is present in the shrub understory in half of the communities sampled. Other shrub species that are occasionally present are <i>Cornus sericea, Philadelphus lewisii, Prunus virginiana, Crataegus douglasii, Salix lucida ssp. lasiandra</i>, and <i>Toxicodendron rydbergii</i>. The herbaceous layer is sparse to moderately populated with a variety of grasses, graminoids and forbs, including <i>Juncus balticus, Eleocharis palustris, Achillea millefolium, Rumex crispus, Clematis ligusticifolia, Urtica dioica, Solidago canadensis</i>, and <i>Artemisia ludoviciana</i>. On more degraded sites, <i>Poa pratensis</i> and <i>Agrostis stolonifera</i> are abundant. |

This association occurs on moderate slopes of predominantly southeastern aspects at elevations from 6000-7300 feet. The slopes are often slightly to moderately rocky. Pinus edulis dominates the abundant tree layer, with Juniperus deppeana and Juniperus monosperma also present. There is a sparse shrub understory, primarily of Quercus X pauciloba (= Quercus undulata). The grass layer is abundant to luxuriant and is dominated by Muhlenbergia dubia. Other grasses present are Piptochaetium fimbriatum, Bouteloua gracilis, Bouteloua curtipendula, Schizachyrium scoparium and Andropogon gerardii. This plant association occurs at higher elevations than most of the Pinus edulis series. On north-facing slopes Pinus ponderosa may be common. No phases have been described of suggested for this association. |

Deschampsia caespitosa - Horkelia marinensis Herbaceous Vegetation

This association is only known from the Point Reyes National Seashore, California. Information about its global characteristics is not available without additional inventory. It was likely to be more widespread along the coast from Santa Cruz County, California, north to Washington, prior to the introduction of invasive exotic annual and perennial grasses. Other similar stands at Salt Point State Park occur adjacent to the coastal bluffs as a rim of native grassland adjacent to non-native annual and perennial grassland. Stands of this grassland association form an intermittent to continuous herb layer of up to 25% mosses and lichens, 40-50% cover at 0-25 cm and 7-15% at 25-50 cm tall. This association is dominated by <i>Deschampsia caespitosa</i>. <i>Horkelia marinensis</i> is usually from 1-18% cover. Other species are characteristic of coastal dunes and include <i>Cardionema ramosissimum, Armeria maritima, Gamochaeta purpurea (= Gnaphalium purpureum), Vulpia bromoides</i> (exotic), <i>Carpobrotus edulis</i> (exotic), and <i>Holcus lanatus</i> (exotic). |

This rich graminoid fen community type is found in the midwestern prairie and prairie-forest border region of the United States. Stands are found on wet, saturated soils (but not seepage) with groundwater influence, or on lake margins and/or grounded or floating mats. Peat depths may be less than 0.5 m, and stands may be on shallow, highly decomposed sedge peat, or rarely on wet, mineral soil. Sphagnum spp. are typically absent. The graminoid layer is often dominated by Carex lasiocarpa, with associates of Carex aquatilis, Carex buxbaumii, Carex interior, Carex livida, Carex pellita, Carex sartwellii, Carex stricta, Decodon verticillatus, Dulichium arundinaceum, Eleocharis elliptica, Eleocharis palustris (= Eleocharis smallii), Eriophorum angustifolium, Glyceria grandis, Schoenoplectus acutus (= Scirpus acutus), and Schoenoplectus subterminalis (= Scirpus subterminalis). Eleocharis rostellata and Cladium mariscoides occur less frequently. Grasses include Calamagrostis canadensis and Calamagrostis stricta. Prairie and other herbs are present, such as Cardamine pratensis, Comarum palustre (= Potentilla palustris), Euthamia graminifolia, Galium labradoricum, Impatiens capensis, Lobelia kalmii, Lycopus uniflorus, Lysimachia thyrsiflora, Menyanthes trifoliata, Pedicularis lanceolata, and Triadenum fraseri. Brown mosses may include Leptodictyum riparium (= Amblystegium riparium), Calliergonella cuspidata, Campylium polygamum, Campylium stellatum, and Fissidens adianthoides. Shrub cover is variable and may exceed 25%. Betula pumila, Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda), Salix candida, Salix pedicellaris, and Spiraea tomentosa may be present. A more marly beach fen subtype is found in Indiana, and contains a combination of prairie and alkaline fen indicators. Western Ohio stands lack some of the more boreal species. |
