Schoenoplectus americanus Tidal Herbaceous Alliance

This alliance includes tidal, mesohaline to oligohaline marshes dominated or codominated by Schoenoplectus americanus (= Scirpus olneyi). Other associated species can include Spartina patens, Spartina alterniflora, Spartina cynosuroides, Phragmites australis, Juncus roemerianus, Typha spp., and Typha domingensis. The general aspect and species composition of this vegetation are variable, not only among occurrences, but also over the course of the growing season. Dominance patterns are not well understood but are likely related to gradients in salinity and hydrology. This alliance is known from the Gulf Coast of Texas, the Chenier Plain of Louisiana, and the mid-Atlantic coast of Maryland and Delaware; it may also occur along the Gulf Coast of Mississippi and Alabama and possibly along the lower Atlantic coast of the United States. |

Tsuga canadensis - Betula alleghaniensis Saturated Forest
» more details
accession code: VB.CC.27386.TSUGACANADENSIS
|
Midwestern Ecology Working Group... |

|
This community is found in the central Great Lakes region of the United States and adjacent Canada. Stands occur on wet-mesic areas with imperfectly drained sandy loam/loam or silty clay soils that are often saturated. These areas occur on gentle slopes, drainageways, and bordering lakes and wetlands. The nutrient status is generally poor to medium. The overstory of this community is composed of conifers with a moderate amount of deciduous trees. Tsuga canadensis is usually the most abundant species with Acer rubrum, Acer saccharum, Betula alleghaniensis, Pinus strobus, and Thuja occidentalis less common. Abies balsamea in northern Wisconsin and Michigan. The shrub layer is not well-developed in mature stands with dense canopies, but shrubs are often abundant in disturbed or young stands. Shrubs that may be present include Amelanchier spp., Corylus cornuta, Lonicera canadensis, Prunus pensylvanica, and Vaccinium spp. Common herbaceous species include Clintonia borealis, Coptis trifolia, Cornus canadensis, Dryopteris carthusiana, Maianthemum canadense, Trientalis borealis, Viola spp., and others. |

Sporobolus silveanus - Carex meadii Herbaceous Vegetation

accession code: VB.CC.27292.SPOROBOLUSSILVE

|
This community occurs on Alfisols in the northeastern portion of the Blackland Prairie of Texas. Sporobolus silveanus, Carex meadii, and Fimbristylis puberula are the dominant species. Other typical species include Tridens strictus, Dichanthelium oligosanthes, Panicum virgatum, Paspalum floridanum, Coelorachis cylindrica, Neptunia lutea, Linum medium, Symphyotrichum ericoides (= Aster ericoides), Symphyotrichum pratense (= Aster sericeus var. microphyllus), Helianthus mollis, Liatris pycnostachya, Liatris aspera, Coreopsis tinctoria, Baptisia sphaerocarpa, Baptisia bracteata var. leucophaea (= Baptisia leucophaea), Eryngium yuccifolium, and Silphium radula (= Silphium asperrimum). This association sometimes occurs within mima-mound microtopography. Mima mounds are small circular hills which are often more than 1 m in height and 1-14 m across (Diamond and Smeins 1993). Three distinct vegetation zones and as many as four different habitats can occur within a single mound (Collins 1975). |

This association is the basic equivalent of more acidic Saxifraga michauxii Herbaceous Vegetation (CEGL004524) that covers examples on mafic or basic metasedimentary rocks (or felsic rocks influenced by base-rich seepage), containing plants that prefer higher pH conditions. The Basic Type is distinguished from the Acidic Type by the presence of plants such as Cheilanthes lanosa, Hylotelephium telephioides (= Sedum telephioides), Aquilegia canadensis, and Pycnanthemum incanum. |

This alliance consists of pinyon - juniper woodlands in the Davis and Chisos mountains of Trans-Pecos Texas, occurring at 1500-2000 m (5000-6500 feet) elevation, and extending into Mexico. Pinus cembroides is the dominant pine. Other typical tree species include Juniperus deppeana, Juniperus flaccida, Juniperus coahuilensis (= Juniperus erythrocarpa), Quercus grisea, and Quercus emoryi. Shrub and herbaceous species include Mimosa dysocarpa, Agave lechuguilla, Salvia regla, Muhlenbergia emersleyi, Muhlenbergia montana, Piptochaetium pringlei, and Bouteloua curtipendula. These woodlands occur on steep, rocky slopes, mesas, and higher elevation canyons, mostly associated with igneous substrates. |
