Name: Onoclea sensibilis - (Adiantum pedatum) - Impatiens capensis - Carex plantaginea Herbaceous Vegetation Reference: Eastern Ecology Working Group of... Description: These small seepage wetlands occur as pockets or narrow linear patches within northern hardwood forests where seepage waters create saturated and mineral-rich conditions. Streamheads and lower slopes are typical settings, and the ground surface is usually gently sloping. Though generally shaded by the overhanging forest canopy, this association is defined by the herbaceous vegetation which is distinctly different from the herb and shrub layers in the surrounding forest. Shrub cover is generally low, and herb cover is lush (typically in the range of 60-85%). Bryophytes may be present but are often patchy. Herb composition is variable depending on the nutrient status of the soil and seepage water. Ferns, such as <i>Onoclea sensibilis, Athyrium filix-femina</i>, and <i>Matteuccia struthiopteris</i>, may be prominent. <i>Impatiens capensis</i> and <i>Arisaema triphyllum</i> are typical forb species. On the more enriched sites, <i>Adiantum pedatum, Hydrophyllum virginianum, Impatiens pallida, Milium effusum, Carex platyphylla</i>, and/or <i>Carex plantaginea</i> may be present. Other species commonly recorded from this vegetation are <i>Carex scabrata, Carex debilis, Polystichum acrostichoides, Glyceria striata, Solidago caesia</i>, and <i>Ageratina altissima (= Eupatorium rugosum)</i>.  Accession Code: VB.CC.30988.CEGL006409 Plot-observations of this Community Concept: 0
