Translated Name:New York Ironweed - Eastern Marsh Fern - Skunk-cabbage Seepage Meadow
Colloquial Name:Mid-Atlantic Rich Seep
These small wetlands (<1-6 acres) occur as patches within the forest matrix where calcareous groundwater discharge is present throughout the growing season. The substrate may vary from mineral soils to sapric peat (muck). Peat deposits, when present, are generally thin (<50 cm). This association is characterized by a highly variable species composition. Juniperus virginiana may be present, and tall shrubs may be present at low cover (<10%) and include Salix spp., Lindera benzoin, and Toxicodendron vernix. The short-shrub layer is also sparse and often dominated by willows. Dasiphora fruticosa ssp. floribunda (= Pentaphylloides floribunda) is not a typical associate, and if present, is at low cover. The shrub layers may contain invasive shrubs, especially Rosa multiflora, Lonicera morrowii, and Berberis thunbergii. Open sites with little or no woody plant cover often are dominated by graminoids, while more shaded sites have a higher cover of forb species. Herbaceous vegetation typically exceeds 90% and may reach 2 m in height in some forb species. Typical forb species include Vernonia noveboracensis, Thelypteris palustris, Viola spp., Packera aurea (= Senecio aureus), Symplocarpus foetidus, Arisaema triphyllum, Hydrocotyle americana, Eupatorium spp., Impatiens spp., Pycnanthemum verticillatum, Amphicarpaea bracteata, Mitella diphylla, Solidago uliginosa, Drosera rotundifolia, Parnassia glauca, and Chelone glabra. Typical graminoid species include Carex leptalea, Carex granularis, Carex atlantica, Carex debilis, Leersia oryzoides, Muhlenbergia glomerata, Rhynchospora alba, and Poa palustris. The invasive plants Lythrum salicaria and Microstegium vimineum may be present, the former particularly in more open seeps. Mosses are usually present but are typically <5% of total vegetation cover.

USNVC Credits: Detailed Description of the National Vegetation Classification Types

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)
  • National Marine Fisheries Service (NMFS)
  • U.S. Army Corps of Engineers (USACE)
  • U.S. Navy (NAVY)
  • Bureau of Land Management (BLM)
  • Fish and Wildlife Service (FWS)
  • National Park Service (NPS)
  • U.S. Geological Survey (USGS)
  • Environmental Protection Agency (EPA)
  • National Aeronautics and Space Administration (NASA)
Non U.S. Government
  • NatureServe (NS)
  • Ecological Society of America (ESA)

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.
