Quercus laurifolia - Nyssa biflora / Clethra alnifolia - Leucothoe axillaris Wet Forest
Translated Name: Laurel Oak - Swamp Tupelo / Coastal Sweet-pepperbush - Coastal Doghobble Wet Forest
Common Name: Atlantic Coastal Plain Wet Nonriverine Oak Flatwoods Forest
Unique Identifier: CEGL007447
Classification Approach: International Vegetation Classification (IVC)
Summary: This forest occurs in wetter sloughs associated with Quercus michauxii - Quercus pagoda / Clethra alnifolia - Leucothoe axillaris Wet Flatwoods Forest (CEGL007449), on extensive flats with a high water table providing seasonally to semipermanently saturated (and rarely flooded) conditions. This forest is believed to occur from Virginia to Georgia, in the Atlantic Coastal Plain. The canopy is dominated by Quercus laurifolia, with lesser amounts of Nyssa biflora and Acer rubrum var. trilobum often present as well. Clethra alnifolia and Leucothoe axillaris are typical shrubs. Herbs including Osmunda regalis, Saururus cernuus, or Woodwardia areolata may be more abundant than the shrubs.

NatureServe Conservation Status
Global Status: G2G3 (20Apr2015)
Rounded Global Status: G2 - Imperiled
Reasons: Because of the alteration of hydrology and drainage of habitat for these forests, they are much less plentiful and more degraded than they probably were in the past.

Vegetation

Vegetation Summary: The canopy of stands of this type is dominated by Quercus laurifolia, with lesser amounts of Nyssa biflora and Acer rubrum var. trilobum often present as well. Clethra alnifolia and Leucothoe axillaris are typical shrubs.


Environmental Setting

Wetland Indicator: Y
Environmental Summary: This forest occurs in wetter sloughs associated with Quercus michauxii - Quercus pagoda / Clethra alnifolia - Leucothoe axillaris Wet Flatwoods Forest (CEGL007449), on extensive flats with high water table providing seasonally to semipermanently saturated (and rarely flooded) conditions. In general, these forests occur on poorly drained interstream flats with fine-textured mineral soils. Hydrology and species composition separate these communities from alluvial bottomland communities with somewhat similar canopy composition. They may occur on the margins of large peatlands, and on smaller upland flats where they experience mostly saturated soils as a result of poor drainage, high water tables, and perhaps sheet flow from adjacent pocosins.
