This calcareous grassland community is found in parts of the northern prairie-forest border in the midwestern United States, particularly in Illinois. Stands occur on upper slopes of hills, primarily on southern and western aspects. Soils are very shallow to moderately deep (0-40 cm) and well-drained to somewhat rapidly drained. The soil pH is high due to the calcareous bedrock at or near the surface, which is either limestone or dolomite. Dominant grasses include <i>Schizachyrium scoparium</i> and <i>Bouteloua curtipendula</i>. Some forbs that are typical of these calcareous grasslands include <i>Symphyotrichum sericeum (= Aster sericeus), Blephilia ciliata, Brickellia eupatorioides (= Kuhnia eupatorioides), Desmanthus illinoensis, Lithospermum canescens, Eleocharis compressa, Clinopodium arkansanum (= Satureja arkansana), Muhlenbergia cuspidata, Penstemon hirsutus</i>, and <i>Scutellaria parvula</i>. |

Impatiens pallida - Cystopteris bulbifera - Adoxa moschatellina - (Chrysosplenium iowense, Aconitum noveboracense) Algific Talus Herb Vegetation

The algific talus slope community type is found in the Driftless Area of the upper midwestern United States. Stands occur at the base of steep north-facing dolostone talus slopes. Continuous cold-air drainage from fissures and ice caves in the talus creates a cool, moist microclimate that keeps summer temperatures from rarely exceeding 16°C, and winter temperatures rarely below -10°C. Exposed talus and boulders may be common. Stands vary in size from a few m square to narrow linear complexes that extend up to 1.5 km, depending on their geology. The vegetation is dominated by forbs, ferns, and mosses, which cover much of the talus. The most abundant species are <i>Adoxa moschatellina, Circaea alpina, Cornus canadensis, Cystopteris bulbifera, Impatiens pallida, Maianthemum canadense, Mertensia paniculata</i>, and <i>Mitella nuda</i>. Other characteristic species include <i>Aconitum noveboracense</i> and <i>Chrysosplenium iowense</i> (a boreal disjunct). <i>Carex norvegica</i> is reported in Wisconsin. Associated shrub and tree species include <i>Abies balsamea, Acer spicatum, Betula papyrifera, Fraxinus nigra</i>, and <i>Rhamnus alnifolia</i>. Relict and disjunct vascular plants found only on algific talus slopes include <i>Aconitum noveboracense</i> and <i>Chrysosplenium iowense</i>. Among the land snails, the same is true for <i>Discus macclintocki</i> and <i>Vertigo brierensis</i>, whereas others occur mostly on algific talus slopes, including <i>Catinella gelida, Vertigo hubrichti ssp. hubrichti</i>, and <i>Vertigo iowaensis</i>. |

This community is found in the Sandhills region of the central Great Plains on level valley bottoms bordering streams, lakes, and marshes. The water table is 15-30 cm below the surface, and these sites remain saturated throughout the year but never become flooded. The soils are deep (0.7-7 m) peat or muck formed from decaying herbaceous vegetation. Surface mounding is characteristic of many sites. The vegetation consists mainly of hydrophytic herbaceous species. Stands are typically dominated by sedges, including <i>Carex interior, Carex lacustris, Carex nebrascensis, Carex prairea</i>, and <i>Carex sartwellii</i>. Other abundant species are <i>Calamagrostis canadensis, Eleocharis elliptica, Glyceria striata</i>, and <i>Thelypteris palustris</i>. In areas of well-preserved fibrous peat, <i>Carex pellita, Carex interior</i> and <i>Carex prairea</i> dominate. Where the peat is more degraded and mucky, <i>Carex lacustris</i> and <i>Carex nebrascensis</i> often dominate, with <i>Carex aquatilis</i> common in some sites. Some parts of the fen may be dominated by taller graminoids, such as <i>Phragmites australis, Schoenoplectus acutus (= Scirpus acutus)</i>, and <i>Typha latifolia</i>, with a ground layer of <i>Onoclea sensibilis</i> and <i>Thelypteris palustris</i>. In other parts, shrub cover can be high. Shrub species include <i>Salix petiolaris, Cornus sericea (= Cornus stolonifera)</i>, and <i>Salix</i> spp. Many disjunct boreal species are commonly found in the fibrous peat, including <i>Symphyotrichum boreale (= Aster borealis), Doellingeria umbellata var. pubens (= Aster umbellatus var. pubens), Eriophorum angustifolium, Eriophorum gracile, Muhlenbergia glomerata</i>, and <i>Ophioglossum pusillum</i>. |

This post oak - mixed oak woodland community is found in the upper reaches of the Mississippi River Alluvial Plain of the southeastern United States, particularly in southeastern Missouri and, at least historically, in adjacent states. Stands occur on gentle to moderately steep mid and upper slopes of hills and plains, on ridges and knolls of terraces, and on ridgetops. Soils are deep (100 cm or more), well-drained, and comprised of eolian or alluvial sand and loess. The canopy is 7-30 m tall, dominated by <i>Quercus alba, Quercus falcata, Quercus stellata</i>, and <i>Quercus velutina</i>. The understory is 2-8 m tall with less than 75% cover. Shrubs and small trees are both present in the understory. The low-shrub layer contains <i>Vaccinium pallidum</i> in Missouri. The ground cover consists of mixed herbaceous species with a cover of 10-60%. Herbaceous species include <i>Saccharum alopecuroidum, Polygonella americana, Helianthus microcephalus, Solidago odora, Asclepias variegata, Desmodium viridiflorum, Croton michauxii (= Crotonopsis linearis), Cyperus grayoides</i>, and <i>Sida elliottii</i>. Lichens and mosses are often present in drier examples of this community. This community is historic in Arkansas and perhaps in Kentucky. |
