Alnus serrulata / Sanguisorba canadensis - Calamagrostis canadensis Seepage Shrubland
Translated Name: Hazel Alder / Canadian Burnet - Bluejoint Seepage Shrubland
Common Name: Southern Appalachian Ultramafic Fen (Tall Herb Type)
Unique Identifier: CEGL004252
Classification Approach: International Vegetation Classification (IVC)
Summary: This is a mafic marsh. Other species include Cornus amomum. More information to be provided by VDNH. This is a tall shrubland (denser than the related Alnus serrulata / Sanguisorba canadensis - Parnassia grandifolia - Helenium brevifolium Seepage Shrubland (CEGL003917)) with coarse herbs than occur in mucky fens.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: Uncertain if this association is best placed in this alliance. These (CEGL004252 and CEGL003917) are two shrublands that occur in a flat area of the Southern Blue Ridge that is underlain by ultramafic and mafic rocks and has many headwater streams and seepage areas. The two are distinctly different environmentally and floristically. Plots of both in the regional dataset have been examined, and they are quite distinct in quantitative analysis. CEGL003917 is a very low, sparse shrubland that grows in peaty, sphagnous fens and has many "bog" species such as Kalmia carolina, Drosera rotundifolia, Carex sterilis, Calopogon tuberosus, Vaccinium macrocarpon, etc. CEGL004252 is a tall, denser shrubland with coarse herbs that grows in mucky fens. Originally (in the early 1990s), Tom Rawinski recognized both only in the general category of a "Mafic Fen" and so they were sort of combined in the LAPS book (Grossman et al. 1994) as a rare "type."

NatureServe Conservation Status
Global Status: G1 (10Nov1997)
Rounded Global Status: G1 - Critically Imperiled
Reasons: There are probably fewer than 6 occurrences of this community rangewide; currently there are 3 occurrences documented in Virginia. Each known site is small (less than 3 acres); a total of less than 5 acres are currently documented. Total rangewide acreage is probably less than 10 acres. The range is restricted to the southern Blue Ridge plateau in Virginia, in an area known as "The Glades". Known occurrences are threatened by shrub invasion, which is probably due to fire suppression. Cattle grazing and alterations to hydrology by ditching are also significant threats.
