Caltha palustris - Impatiens capensis - Viola cucullata Seepage Meadow

The U.S. National
Vegetation Classification
Collapse All::Expand All
Translated Name:Yellow Marsh-marigold - Orange Jewelweed - Marsh Blue Violet Seepage Meadow
Colloquial Name:Central Appalachian Woodland Seep
This community is a saturated, herbaceous, small-patch wetland occurring on relatively steep, usually gravelly or bouldery slopes at sites of groundwater discharge. The type is probably scattered in the northern Blue Ridge and parts of the Ridge and Valley province, in areas underlain by base-rich metamorphic, igneous, or sedimentary rocks. Occurrences are more common at, but not restricted to, elevations above 760 m (2500 feet) elevation. Habitats are typically narrow and partially or wholly shaded by tree species rooted in adjacent upland forests. A few occurrences encompass larger spring seeps that may have resulted from the clearing of forested seepage swamps. Vegetation is similar to the herbaceous component of forested seepage swamps but is usually more forb-rich. Characteristic species include Caltha palustris, Impatiens capensis, Viola cucullata, Chelone glabra, Pilea pumila, Chrysosplenium americanum, Lycopus virginicus, Lycopus uniflorus, Packera aurea (= Senecio aureus), Veratrum viride, Laportea canadensis, and Carex gynandra.

This association is highly provisional, and much additional inventory and quantitative data collection are needed before a robust classification can be produced. Some occurrences of this vegetation are natural, while others appear to have resulted from disturbance. Montane seeps are poorly understood and problematic in that most patches fall well below minimum map unit size for vegetation mapping projects. Because of their extremely small, narrow, and linear configuration, they are also difficult to plot-sample without including extraneous vegetation.

This community occupies narrow, relatively steep, usually gravelly or bouldery spring seeps. Underlying bedrock includes base-rich metamorphic and igneous rocks such as Catoctin metabasalt (greenstone) and pyroxene-bearing granites, or calcareous sedimentary rocks. Occurrences are more common at, but not restricted to, elevations above 760 m (2500 feet) elevation. Habitats are typically narrow and partially or wholly shaded by tree species rooted in adjacent upland forests. A few occurrences encompass larger spring seeps that may have resulted from the clearing of forested seepage swamps.

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:

  • 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)

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.
