Name: Quercus palustris - (Quercus stellata) - Quercus pagoda / Isoetes spp. Forest
Reference: Midwestern Ecology Working Group...
Description: This pin oak - cherrybark oak bottomland or flatwoods forest community type is found in the central United States, principally in the Ohio and Mississippi River plains and tributaries. Stands occur on poorly drained terrace flats that are seasonally wet (mostly during winter and early spring and dry in late summer and early fall). Soils are slowly to very slowly permeable due to a high clay content or the presence of a fragipan. This results in a shallow, perched water table during the rainy season (winter and spring) and dry conditions during the summer and fall. Soils are silt loam to silty clay loam, deep, heavy, strongly acidic (pH 5.1-5.5), and poorly drained. Dominant canopy species are <i>Quercus palustris</i> and <i>Quercus pagoda</i>. Other trees often encountered include <i>Ulmus americana, Fraxinus</i> spp., <i>Liquidambar styraciflua, Quercus shumardii</i>, and <i>Quercus stellata</i>. Severe floods due to dams may have eliminated <i>Quercus stellata</i> from most occurrences of this community. <i>Quercus bicolor</i> can be plentiful in northern extensions of this association, while <i>Quercus texana</i> is commonly found in southern occurrences. The subcanopy is sparse and dominated by <i>Acer rubrum</i>, although a diverse mixture of bottomland species can be present as well. <i>Ilex decidua</i> and <i>Crataegus viridis</i> dominate the shrub layer. <i>Carex</i> spp. dominate the herbaceous layer, but a diverse mixture of forbs can also be present. <i>Pycnanthemum tenuifolium</i>, an herbaceous species more commonly associated with dry uplands, reflects the dry conditions seasonally found in this forest. <i>Campsis radicans</i> and <i>Toxicodendron radicans</i> dominate the vine stratum. <i>Isoetes</i> spp., characteristic of this community, are found often in the shallow pools. As with other flatwood forests, vegetation density and diversity are largely regulated by the duration and depth of seasonal flooding and summer drought.
