CEGL006446 Bidens cernua - Verbena hastata - Polygonum spp. Marsh

Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Nodding Beggarticks - Swamp Verbena - Smartweed species Marsh

Colloquial Name: Mixed Forb Marsh

Hierarchy Level:  Association

Type Concept: This variable wetland type occurs in depressions, drainages, and basins that contain ponded water throughout the year. In general, waterflow out of the sites is restricted, either due to naturally occurring depressions or from beaver activity, roads, or berms. The vegetation is dominated by species that are tolerant of standing water, and species composition is extremely variable among sites. Common species may include Eleocharis acicularis, Verbena hastata, Bidens cernua, Eupatorium maculatum, Leersia oryzoides, Polygonum hydropiper, Polygonum sagittatum, Equisetum arvense, Symphyotrichum novae-angliae, Schoenoplectus americanus, Carex stipata, Carex vulpinoidea, Eupatorium perfoliatum, Poa trivialis, Ludwigia palustris, and/ or Toxicodendron radicans.

Floristics: This herbaceous-dominated association contains standing water for most or all of the year and is often associated with impounded drainages, ponded areas near streams, or saturated areas surrounding drainages. The vegetation is dominated by species that are tolerant of standing water, and species composition is extremely variable among sites. Common species include Eleocharis acicularis, Verbena hastata, Bidens cernua, Eupatorium maculatum, Leersia oryzoides, Polygonum hydropiper, Polygonum sagittatum, Equisetum arvense, Symphyotrichum novae-angliae, Schoenoplectus americanus, Carex stipata, Carex vulpinoidea, Eupatorium perfoliatum, Poa trivialis, Ludwigia palustris, and/ or Toxicodendron radicans.

Environmental Description:  This variable wetland type occurs in depressions, drainages, and basins that contain ponded water throughout the year. Waterflow out of the sites is typically restricted, either due to naturally occurring depressions or from beaver activity, roads, or berms. The vegetation is often restricted to the edges of the basins, with open water remaining in the center. These wetlands typically occur on very poorly drained soils such as mucky silt loam, shallow mucky peat, and, less occasionally, on ponded gravelly sand.
Geographic Range: This community is described from Pennsylvania and New Jersey and probably ranges northward.
