G654 Quercus lyrata - Quercus stellata - Nyssa sylvatica Flatwoods & Pond Forest Group
Type Concept Sentence: These are primarily Quercus-dominated nonriverine wetland forests found in ponds, depressions, and flats along small streams, from Maryland south to Alabama and Georgia, and north and west to Kentucky, Missouri and possibly Oklahoma.
Common (Translated Scientific) Name: Overcup Oak - Post Oak - Blackgum Flatwoods & Pond Forest Group
Colloquial Name: South-Central Flatwoods & Pond Forest
Hierarchy Level: Group
Type Concept: These primarily Quercus-dominated nonriverine wetland forests are found in ponds, wet depressions, flats along small streams, and other related environments from Maryland south to Alabama and Georgia, and north and west to Kentucky, Missouri and possibly Oklahoma. They encompass a variety of hydroperiods from longer (wetter) areas dominated by Quercus lyrata and Quercus phellos, to shorter mesic or seasonally wet environments dominated by Quercus alba, Nyssa sylvatica, and/or Quercus stellata. Other trees that may be present include Betula nigra, Carya carolinae-septentrionalis, Fraxinus americana, Liquidambar styraciflua, Nyssa biflora, Quercus michauxii, Quercus oglethorpensis, Quercus shumardii, and Quercus similis. Shrubs may include Cephalanthus occidentalis and Lyonia lucida. Herbs may include Carex albolutescens, Carex intumescens, Carex joorii, Chasmanthium laxum, Cinna arundinacea, Croton michauxii var. ellipticus, Danthonia spicata, Pleopeltis polypodioides ssp. michauxiana, Zephyranthes atamasca, and the moss Climacium americanum. The component associations are primarily from the Interior Low Plateau, southern Piedmont, Ridge and Valley/Cumberlands, and Ozarks, with some more peripheral occurrences in the northern Piedmont, mid-Atlantic Coastal Plain, and Ouachitas.
Diagnostic Characteristics: These nonriverine wetland forests occur in ponds, wet depressions, flats along small streams, and other related environments from Maryland south to Alabama and Georgia, and north and west to Kentucky, Missouri and possibly Oklahoma. They are primarily Quercus-dominated, with the dominant species varying by hydroperiod. Wetter (longer hydroperiod) areas are typically dominated by Quercus lyrata and Quercus phellos, with shorter mesic or seasonally wet environments being dominated by species such as Quercus alba, Quercus stellata, and/or Nyssa sylvatica.

Physiognomy and Structure: These are nonriverine wetland forests dominated by moderately tall trees. They have moderately closed canopies, and their shrub and herb layers vary in density and diversity depending on hydroperiod, which can vary from longer (wetter) to shorter (less wet). Longer hydroperiod areas tend to be more open and less diverse.
Floristics: This vegetation encompasses a variety of hydroperiods from longer (wetter) areas dominated by Quercus lyrata and Quercus phellos, to shorter mesic or seasonally wet environments dominated by Quercus alba, Nyssa sylvatica, and/or Quercus stellata. Other trees that may be present include Betula nigra, Carya carolinae-septentrionalis, Fraxinus americana, Liquidambar styraciflua, Nyssa biflora, Quercus michauxii, Quercus oglethorpensis, Quercus shumardii, and Quercus similis. Shrubs may include Cephalanthus occidentalis and Lyonia lucida. Herbs may include Carex albolutescens, Carex intumescens, Carex joorii, Chasmanthium laxum, Cinna arundinacea, Croton michauxii var. ellipticus (= Croton willdenowii), Danthonia spicata, Pleopeltis polypodioides ssp. michauxiana, Zephyranthes atamasca, and the moss Climacium americanum.
Dynamics: These primarily Quercus-dominated nonriverine wetland forests encompass a variety of hydroperiods from longer (wetter) areas to shorter mesic or seasonally wet environments. The hydrology is driven by rainwater and groundwater, but not riverine flooding.
Environmental Description: These primarily nonriverine wetland forests are found in ponds, wet depressions, flats along small streams, and other related environments. They encompass a variety of hydroperiods from longer (wetter) to shorter mesic or seasonally wet environments.
Geographic Range: This vegetation ranges from Maryland south to Alabama and Georgia, and north and west to Kentucky, Missouri and possibly Oklahoma, primarily in the Interior Low Plateau, southern Piedmont, Ridge and Valley/Cumberlands, and Ozarks, with some more peripheral occurrences in the northern Piedmont, mid-Atlantic Coastal Plain, and Ouachitas.
