This community type is found in deep marshes throughout the midwestern United States and Canada. The vegetation is dominated by relatively pure stands of Typha spp., either Typha latifolia or Typha angustifolia or both. Many associates could occur. This type may simply be a less diverse variation of Typha spp. - Schoenoplectus acutus - Mixed Herbs Midwest Herbaceous Vegetation (CEGL002229), or is a semi-natural type resulting from human disturbance to wetlands. |

This alliance encompasses ~Rubus$-dominated areas at high elevations in the Southern Blue Ridge. This includes grassy balds (open montane grasslands), areas where the Balsam Woolly Adelgid has caused ~Abies fraseri$ death, or other disturbed areas such as landslide scars that create open conditions. |

Scolochloa festucacea Herbaceous Vegetation

Midwestern Ecology Working Group... |

This sprangletop marsh type is found in the northeastern Great Plains and northern tallgrass prairie region of the United States and Canada. Stands occur on sites with standing water for part of the growing season. The water table may be above the surface for only a few weeks in spring after heavy rains or constantly until mid-summer. Stands dominated by Scolochloa festucacea can be found on marginally fresh to moderately saline stands. The soils are typically medium to fine-textured and often have an accumulation of organic matter. Graminoids 0.5-1.0 m tall dominate the moderately dense to dense vegetation cover. Forbs are not common and shrubs are very rare. Scolochloa festucacea is the single most abundant species and may occur in almost monotypic stands. Other abundant species include Carex atherodes, Carex laeviconica, Eleocharis palustris, Glyceria grandis, Juncus balticus, Sium suave, and Typha latifolia. |

Piedmont Mafic Cliff Sparse Vegetation

This sparsely vegetated cliff association occurs in the Piedmont of the southeastern United States. Examples are found on steep to vertical outcrops of mafic igneous or metamorphic rocks, in topographically low settings such as river bluffs that are not subject to flood scouring. Substrates include gabbro, amphibolite, greenstone, basalt, and sometimes andesite and diorite. Vegetation is low in cover, and is confined to lichens and plants growing on bare rock and to sparse herbs, shrubs, and trees rooted in local pockets of deeper soil. The flora is a mix that usually includes drought-tolerant, shade-intolerant species, species shared with surrounding forests, and sometimes local occurrences of wetland species associated with small seepage zones. Most of the species are acid-tolerant, but several more basophilic species are present. Frequent basophilic species include Aquilegia canadensis, Sanguinaria canadensis, Arabis spp., Anemone berlandieri, Aristolochia serpentaria, Rhus aromatica, and Hydrangea arborescens. Other frequent herbs include Danthonia spicata, Schizachyrium scoparium, Hieracium venosum, Asplenium platyneuron, Pleopeltis polypodioides (= Polypodium polypodioides), Opuntia humifusa, Tephrosia virginiana, Cheilanthes lanosa, and Cheilanthes tomentosa. Frequent woody species include Juniperus virginiana, Carya glabra, Ulmus alata, Chionanthus virginicus, and Ostrya virginiana. Lichens and bryophytes may be abundant or scarce. |
