Bidens cernua - Verbena hastata - Polygonum spp. Marsh
Translated Name: Nodding Beggarticks - Swamp Verbena - Smartweed species Marsh
Common Name: Mixed Forb Marsh
Unique Identifier: CEGL006446
Classification Approach: International Vegetation Classification (IVC)
Summary: 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.

Vegetation

Vegetation Summary: 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 Setting

Wetland Indicator: Y
Environmental Summary: 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.
