CEGL002406 Quercus palustris - (Quercus bicolor) / Carex crinita / Sphagnum spp. Wet Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pin Oak - (Swamp White Oak) / Fringed Sedge / Peatmoss species Wet Forest
Colloquial Name: Pin Oak - Swamp White Oak Sinkhole Flatwoods
Hierarchy Level: Association
Type Concept: This pin oak - swamp white oak sinkhole flatwoods is found in the United States in Missouri and Arkansas. Stands occur in broad sinkhole basins. Soils have a fragipan which impedes drainage and roots. The soils of this community receive groundwater from water fluctuations in the ponds. This water, combined with rainwater, keeps the soils saturated during wet periods and moist during dry periods. The soils have a pH below 5.5. Hydrophytic plants dominate this community. The forest is a mixed deciduous hardwoods community. The dominant trees are 20-30 m tall, and the canopy is closed. Quercus palustris, Quercus bicolor, and Diospyros virginiana are present. The understory is poorly developed or absent. When present, it ranges from 5-7 m in height. Shrubs may occur with small trees to make up the understory. Species include Alnus serrulata and Cephalanthus occidentalis. The ground cover consists of ferns, mixed sedges, and moss tussocks. Ferns include Osmunda regalis and Onoclea sensibilis, herbs include Viola lanceolata, and mosses include Climacium americanum and Sphagnum spp.

Classification Comments: Concept of the type was originally taken from the Missouri state type - Forested Acid Seep (Nelson 1985), but that type was amended so that forested acid seeps were combined with acid seeps, ~Carex crinita - Osmunda spp. / Sphagnum spp. Acidic Herbaceous Seep (CEGL002263)$$, and acid sinkhole ponds were separated out as a sinkhole flatwoods (M. Leahy pers. comm. 1999). This type has been amended to follow the new Missouri concept. Type fits a seasonally saturated hydrology.

Dynamics: No Data Available
Environmental Description: This community occurs in broad sinkhole basins. The slopes on which it occurs are level to gentle. Soils have a fragipan which impedes drainage and roots. The soils of this community receive groundwater seepage. The groundwater fluctuates, causing water levels to flood the surface in highly acidic sinkhole ponds. This water, combined with rainwater, keeps the soils saturated during wet periods and moist during dry periods (Nelson 1985).
Geographic Range: This pin oak - swamp white oak sinkhole flatwoods is found in the United States in Missouri and Arkansas.
