Habitat Overview Members of this habitat include plants that require both shaded, humid microclimates and nutrient-rich soils. Also included are the herbivores associated with these plants; one insectivore, the Kentucky Warbler is included since it nests on the ground in the rich herb cover typical of these habitats.

This particular group occurs fairly widely, being found in two or more of the physiographic regions of the state; species that require the same kind of habitat conditions but are restricted to just one of the provinces are treated in more narrowly-defined groups.

Some examples of this habitat are directly associated with rock formations that weather to produce soils that have both high nutrient content and relatively high pH These include mafic rocks, such as gabbro, diabase, basalt, and amphibolite. Calcareous rocks, including limestone in a few places in the mountains and marl and shell-deposits in the Outer Coastal Plain are also occupied. Most of these examples occur on slopes, usually with an east- or north-facing exposure, limiting insolation and helping preserve the cool, moist microclimates needed by the species of this habitat. Where particularly rich soils are created, species normally restricted to cool slopes can grow on flats, including those on the tops of ridges.

The other main examples of this habitat are associated with the rich alluvial soils that are produced where streams flow through nutrient-rich rock formations. These soils are deposited in bottomlands, where the soils are kept wet by stream flow and where the microclimate is kept moist due to evaporation from the abundant surface waters. Species growing well out on the floodplain must be adapted to surviving at least some degree of flooding, but species on the lower slopes and upper terraces are less so.

These habitats are fairly common in the mountains and Piedmont; in the Coastal Plain they are confined to brownwater rivers and a few wet flats associated with calcareous substrates.
