CEGL007059 Alnus serrulata Southern Interior Seepage Shrubland
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Hazel Alder Southern Interior Seepage Shrubland
Colloquial Name: Southern Interior Alder Seepage Thicket
Hierarchy Level: Association
Type Concept: This association represents saturated shrub vegetation dominated by Alnus serrulata from the Interior Low Plateau and Upper East Gulf Coastal Plain ecoregions of the southeastern United States. This association occurs as stands adjacent to streamside or hillside herbaceous seepages, or as shrub-dominated inclusions in various types of saturated forest. It also may be found as small patches in wetlands which are influenced by beaver activity. These sites may occur on the edges of floodplains along low-gradient streams. Hydrology of some sites may also be influenced or enhanced by roads and other human construction. In the Western Highland Rim of Tennessee, small-scale saturated areas dominated by Alnus serrulata may form at the margins of seepage areas otherwise dominated by herbaceous plants, which are classified as ~Carex lurida - Carex leptalea - Parnassia grandifolia - Juncus brachycephalus - (Xyris tennesseensis) Seepage Fen (CEGL004161)$$. Saturated vegetation dominated by Alnus serrulata at Fort Benning, Georgia (East Gulf Coastal Plain - Upper East Gulf Coastal Plain transition region), on the upper ends of beaver ponds, is placed here, at least until another specific association is developed if necessary. These are shrub-dominated inclusions in a Nyssa biflora saturated forest.
