Fagus grandifolia - Magnolia virginiana - (Pinus palustris) / Chasmanthium sessiliflorum Sandhill Streamhead Forest

This forest occurs west of the Mississippi River at narrow streamheads, lower slopes adjacent to sandy streambanks, and in the transition zone from bayheads to small stream forests. Due to juxtaposition between dry, sandy uplands (often with relictual Pinus palustris) and mesic stream courses, the flora of this community exhibits affinities to these different habitats. In addition, seepage is often present. The canopy of this association is dominated by some combination of Magnolia virginiana, Magnolia grandiflora, and Fagus grandifolia. A number of other deciduous species may also be present. A diverse herbaceous layer dominated by ferns, sphagnum moss, and sedges is usually present, ranging from sparse cover on the most uphill portions of this community to nearly 100% coverage in the wetter interior portions. Many of the species found in this type, including many of the herbs, are typical of "baygalls" or wet creek bottom habitats which invariably occur somewhat farther downslope. |

This sandstone cliff community type is found in the northern Great Lakes shorelines of the United States and Canada. The substrate is Precambrian sandstone, which in Michigan is exposed along the southern shoreline of Lake Superior. Cliffs rise up over 50 m in places. Species composition varies somewhat, depending on sandstone type, but sandstone cliffs are very low in botanical diversity for a variety of reasons, including lack of soil for rooting, droughtiness on much of the rock surface, exposure to waves and ice, and in some places, unstable surface prone to wave erosion. Some portions of the cliff are moist from small streams or seepages. Jacobsville Sandstone has cliff faces that are largely unvegetated, with mosses, lichens, and herbs concentrated in seeps and streams. Two common herbs are Sagina procumbens and Stellaria calycantha. Pinguicula vulgaris also grows on moist cliffs. |

This poorly known alliance occurs in mountains of the Great Basin and eastern Sierra Nevada at foothill and lower montane elevations. Stands occur at lower elevations locally on exposed acidic parent materials. At higher elevations stands occur on rocky exposed sites. Stands are characterized by an open canopy of scattered conifer trees codominated by ~Pinus ponderosa$ and ~Pinus jeffreyi$. ~Pinus monophylla$ and ~Juniperus osteosperma$ may also be present. |

This river ledge pavement community is found in the United States and Canada, ranging from northern Michigan, northern Wisconsin and southern Ontario to northern New York. Stands occur as small patches on limestone ledges along a river's shore; these ledges are scoured by river water and ice during periods of peak water flow. Typically, the community has an open canopy with less than 10% cover of trees or shrubs. The ground layer is dominated by grasses and sedges, or a mosaic of pavement patches and grassy patches. Cover of herbs is variable, with some areas having nearly 100% cover. Other areas have a lot of exposed rock pavement, with as little as 15% cover of herbs, and are confined to linear rock crevices. Characteristic species include Euthamia graminifolia, Muhlenbergia richardsonis, Oligoneuron album (= Solidago ptarmicoides), Spartina pectinata, and Sporobolus heterolepis. |
