Onoclea sensibilis - (Adiantum pedatum) - Impatiens capensis - Carex plantaginea Seepage Meadow

The U.S. National
Vegetation Classification
Collapse All::Expand All
Translated Name:Sensitive Fern - (Northern Maidenhair) - Orange Jewelweed - Plantainleaf Sedge Seepage Meadow
Colloquial Name:Enriched Northern Hardwood Forested Seep
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 Onoclea sensibilis, Athyrium filix-femina, and Matteuccia struthiopteris, may be prominent. Impatiens capensis and Arisaema triphyllum are typical forb species. On the more enriched sites, Adiantum pedatum, Hydrophyllum virginianum, Impatiens pallida, Milium effusum, Carex platyphylla, and/or Carex plantaginea may be present. Other species commonly recorded from this vegetation are Carex scabrata, Carex debilis, Polystichum acrostichoides, Glyceria striata, Solidago caesia, and Ageratina altissima (= Eupatorium rugosum).
No Data Available
This type is supported by plot data from parks in Vermont and New Hampshire. Similar vegetation has been observed elsewhere in the region but not generally documented as distinct. Attention to these forested seeps could provide data to refine their classification and distribution.
Synonomy:

Related Type Name:These associations overlap in setting and in some associated species (Arisaema triphyllum, Impatiens capensis).

About spatial standards:
The United States Federal Geographic Data Committee (hereafter called the FGDC) is tasked to develop geospatial data standards that will enable sharing of spatial data among producers and users and support the growing National Spatial Data Infrastructure (NSDI), acting under the Office of Management Budget (OMB) Circular A-16 (OMB 1990, 2000) and Executive Order #12906 (Clinton 1994) as amended by Executive Order #13286 (Bush 2003). FGDC subcommittees and working groups, in consultation and cooperation with state, local, tribal, private, academic, and international communities, develop standards for the content, quality, and transferability of geospatial data. FGDC standards are developed through a structured process, integrated with one another to the extent possible, supportable by the current vendor community (but are independent of specific technologies), and publicly available.

About this document
This document contains type descriptions at the Association level of the U.S. National Vegetation Classification. These descriptions were primarily written by NatureServe ecologists in collaboration with Federal Geographic Data Committee Vegetation Subcommittee and a wide variety of state, federal and private partners as a part of the implementation of the National Vegetation Classification. Formation descriptions were written by the Hierarchy Revisions Working Group. The descriptions are based on consultation with natural resource professionals, published literature, and other vegetation classification systems. The Ecological Society of America's Panel on Vegetation Classification is responsible for managing the review and formal adoption of these types into the National Vegetation Classification. Partners involved in the implementation of the USNVC include:

U.S. Government
  • Department of Agriculture (USDA)
  • Department of Commerce (DOC)
  • Department of Defense (DOD)
  • Department of the Interior (USDI)
  • Forest Service (FS) - Chair
  • National Agriculture Statistical Service (NASS)
  • Natural Resources Conservation Service (NRCS)
  • National Oceanic and Atmospheric Administration (NOAA)

Disclaimer:
Given the dynamic nature of the standard, it is possible a type description is incomplete or in revision at the time of download; therefore, users of the data should track the date of access and read the revisions section of the USNVC.org website to understand the current status of the classification. While USNVC data have undergone substantial review prior to posting, it is possible that some errors or inaccuracies have remained undetected.
