CEGL008474 Alnus serrulata Southeastern Shrub Swamp
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Hazel Alder Southeastern Shrub Swamp
Colloquial Name: Southeastern Alder Swamp
Hierarchy Level: Association
Type Concept: This alder swamp is found in the upper southeastern United States, most probably from Kentucky south to central Alabama and Georgia, and west to Mississippi and Arkansas. These shrublands are found on muck overlying mineral soils, at the edges of forested swamps, or in other related seasonally flooded situations, including depressions in floodplains and the backwaters of lakes and beaver ponds. Hydrologic alteration of systems (e.g., creation of impoundments by the agency of humans and/or beaver) may expand habitat for this association. The vegetation is dominated by tall shrubs, and is characterized by some combination of Alnus serrulata, Viburnum spp., Cornus spp., and Salix spp. In addition, saplings of Acer rubrum are typical. Other shrubs present may include Cephalanthus occidentalis, Decodon verticillatus, and Ilex verticillata. Herbaceous associates include Osmunda regalis, Thelypteris palustris, Galium spp., Typha latifolia, Peltandra virginica, and Carex spp. Tree species such as Acer rubrum and Juglans nigra may exist on the fringes of such an association, occasionally overshadowing parts of the association.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The range of this type may abut the range of ~Alnus serrulata / Calamagrostis canadensis Shrub Swamp (CEGL005082)$$ in the vicinity of the Ohio River; the distinction there is obscure. Occurrences on the edges of impoundments would be assumed to be of lower quality than those in more hydrologically natural situations.

Floristics: Stands of this vegetation are dominated by tall shrubs and are characterized by some combination of Alnus serrulata, Viburnum spp., Cornus spp., and Salix spp. In addition, saplings of Acer rubrum are typical. Other shrubs present may include Cephalanthus occidentalis, Decodon verticillatus, and Ilex verticillata. Herbaceous associates include Osmunda regalis, Thelypteris palustris, Boehmeria cylindrica, Polygonum sagittatum, Commelina virginica, Galium spp., Lycopus spp., Typha latifolia, Peltandra virginica, Mikania scandens, and Carex spp. (e.g., Carex crinita, Carex atlantica). Tree species such as Acer rubrum and Juglans nigra may exist on the fringes of such an association, occasionally overshadowing parts of it. The exotic Murdannia keisak (= Aneilema keisak) may also be present.
Dynamics: Hydrologic alteration of systems (e.g., creation of impoundments by the agency of humans and/or beaver) may expand habitat for this association.
