Carex scabrata - Chrysosplenium americanum Seep Alliance

The U.S. National
Vegetation Classification
This alliance accommodates small seepages with scattered cover of Carex scabrata and small forbs, including Chrysosplenium americanum, Cardamine clematitis, Circaea alpina, and usually also with the moss Rhizomnium appalachianum. Vegetation in this alliance is normally over-shaded by trees rooted in adjacent (non-wetland) communities. The alliance is distributed primarily in the Appalachian Mountains from New Hampshire and Vermont south to West Virginia, and possibly in adjacent Canada.

Translated Name:Eastern Rough Sedge - Golden-saxifrage Seep Alliance
Colloquial Name:Eastern Rough Sedge - Golden-saxifrage Seep
This alliance accommodates small herbaceous seepages with scattered cover of Carex scabrata and small forbs, including Chrysosplenium americanum, Cardamine clematitis, Circaea alpina, and usually also with the moss Rhizomnium appalachianum. Vegetation in this alliance is normally over-shaded by trees rooted in adjacent (non-wetland) communities. The spatial extent of this alliance is small, with individual occurrences normally much less than a hectare in size. Despite its small spatial scale, this alliance is an important component of the diversity of the landscapes in which it occurs. The alliance is distributed primarily in the Appalachian Mountains from New Hampshire and Vermont south to West Virginia, and possibly in adjacent Canada.
These are small Central and Northern Appalachian seepages with Chrysosplenium americanum as a characteristic forb.
Chrysosplenium americanum as a species ranges south to the most northern counties of Alabama, Georgia, and South Carolina, but these are very small-scale occurrences, and this vegetation is not recognized in the Southern Appalachians.

Vegetation in this alliance is normally over-shaded by trees rooted in adjacent (non-wetland) communities. The spatial extent of this alliance is small, with individual occurrences normally much less than a hectare in size.
Examples are dominated by of Carex scabrata and small forbs, including Chrysosplenium americanum, Cardamine clematitis, Circaea alpina, and usually also with the moss Rhizomnium appalachianum.
This alliance consists of small seepages in the Appalachian Mountains with scattered cover of small forbs.

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 Alliance 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.
