Name: A.1694
Reference: EcoArt 2002
Description: This alliance, found in the Great Lakes region and northeastern Great Plains, occurs where circumneutral or slightly calcareous groundwater seeps to the surface. This alliance is dominated by forbs. ~Angelica atropurpurea, Caltha palustris$, and ~Symplocarpus foetidus$ are usual dominants. Other species that may be found include ~Carex lacustris, Carex stricta, Glyceria striata, Impatiens capensis$, and ~Thelypteris palustris$. Shrubs and trees from surrounding vegetation types sometimes occur. Where the cover of these becomes significant, the site is classified as another alliance. Typical woody species include ~Acer rubrum, Fraxinus nigra$, and ~Thuja occidentalis$. ^Stands of this alliance are found on lower slopes of glacial moraines, ravines, and terraces around seepage areas. Peat sometimes accumulates to a depth of 1 m. Other sites have little organic material, with groundwater typically welling up through carbonate encrusted gravel.
