Name: Impatiens pallida - Equisetum scirpoides - Parnassia glauca Seep Alliance
Reference: NatureServe Biotics 2019
Description: This vegetation is found in the northern regions of the Great Lakes in the United States. Stands occur on toeslopes, where constant seepage creates saturated clay soils. Substrate is neither mucky not peaty. Stands are often shaded (up to 90% cover) by adjacent forest types, including <i>Tsuga canadensis</i>- and <i>Acer saccharum</i>-dominated stands. Trees rarely occur in the seepage zone itself, which can be as much as 30 m wide. Characteristic plants include <i>Equisetum scirpoides</i> (often dominant) and <i>Impatiens pallida</i>.
