CEGL005015 Fagus grandifolia - Quercus alba - (Quercus michauxii) - Acer rubrum Flatwoods Forest

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: American Beech - White Oak - (Swamp Chestnut Oak) - Red Maple Flatwoods Forest

Colloquial Name: Beech - Oak - Red Maple Flatwoods

Hierarchy Level:  Association

Type Concept: This lowland forest community is found in the United States in southeastern Indiana and southwestern Ohio. Stands occur on level, loess-covered glacial drift of Illinoisan age. Soils are poorly drained silt loams, with an impermeable layer beneath the topsoil that can slow drainage during wet periods, but impede accessibility of deeper water sources during droughty periods. The community has a moderately dense to dense canopy of deciduous trees. Fagus grandifolia is consistently common. Other common trees include Acer rubrum, Liriodendron tulipifera, Liquidambar styraciflua, Nyssa sylvatica, Quercus alba, Quercus bicolor, Quercus palustris, and Quercus michauxii. Fraxinus americana and Quercus shumardii may be present. Asimina triloba, Carpinus caroliniana, Lindera benzoin, Toxicodendron radicans, and Sambucus nigra ssp. canadensis are common shrubs or small trees. Vitis labrusca is a common, and perhaps characteristic, vine. Abundant understory species include the ferns Botrychium oneidense and Onoclea sensibilis and the herbs Chimaphila maculata, Cinna arundinacea, Impatiens capensis, Panax trifolius, Podophyllum peltatum, and Rubus hispidus.

Classification Comments: This type is based largely on the Indiana state type - Bluegrass Till Plain Flatwoods (Homoya et al. 1988) and Ohio''s Wet Beech Forests (Anderson 1996). The type consists of a mosaic of raised, wet-mesic areas and depressions that are wet. The vegetation varies accordingly. Floristic distinctions between the bluegrass region and the central tillplain need to be worked out, but the bluegrass occurrences do contain Quercus michauxii and Liquidambar styraciflua. Anderson (1996) cites Braun (1936) as noting that Carpinus caroliniana, Aronia prunifolia, Spiraea tomentosa, Ilex verticillata, Vitis labrusca, and Viburnum dentatum var. dentatum are characteristic of this type. To help define the type, stands may require at least 25% basal area or cover of beech (Anderson 1996). In Indiana, this type may also occur in the southwestern part of the state (Spencer County).

Abundant understory species include the ferns Botrychium oneidense and Onoclea sensibilis and the herbs Chimaphila maculata, Cinna arundinacea, Impatiens capensis (= Impatiens biflora), Panax trifolius, Podophyllum peltatum, and Rubus hispidus.

Heavy beech dominance may lead to a sparse representation of other associates. However, logging of the oaks may open up the canopy and favor mesic, shade-intolerant species such as Liriodendron tulipifera and Prunus serotina (Anderson 1996). Ulmus americana has decreased in this type because of Dutch elm disease. In response, Acer rubrum and Fraxinus pennsylvanica may have increased (Anderson 1996).

Dynamics:  No Data Available

Environmental Description:  This community is usually found on loess-covered glacial drift of Illinoisan age, with level topography and poorly drained silt loam soils (Braun 1936). The substrate can form a mosaic of slightly higher, wet-mesic raised areas, and wet depressions. An impermeable layer beneath the topsoil slows drainage often resulting in wet soil conditions (Chapman 1942). In droughty periods, the upper soils dry out, and the impermeable subsoil limits the availability of deeper water sources.

Geographic Range: This lowland forest community is found in the United States in southeastern Indiana and southwestern Ohio.
