USGS-NPS Vegetation Mapping Program Colonial National Historical Park DISTRIBUTION Range: This dry, open, calcareous forest is widely scattered in the Coastal Plain of Virginia and Maryland. Occurrences in Virginia are in highly dissected portions of the inner Coastal Plain in James City, Stafford, Surry, Westmoreland, and York counties. Occurrences in Maryland are in the outer Coastal Plain in Kent County. States/Provinces: MD, VA. Federal Lands: DOD (Yorktown); NPS (Colonial, George Washington Birthplace). CONSERVATION STATUS Rank: G1 (15-Feb-2007). Reasons: This community is restricted to dry, calcium-rich, shell-containing soils of the eastern Virginia and Maryland Coastal Plain. This community is naturally rare and restricted to a specialized edaphic situation that is regionally restricted and extremely rare within this region. Despite relatively intensive inventory, fewer than 30 scattered occurrences totaling less than 20 hectares are known. About 25% of the known patches are located on public lands, but many of these occur in a poor landscape context and are subject to encroachment by invasive weeds. CLASSIFICATION INFORMATION Status: Standard. Confidence: 2 - Moderate. Comments: Classification of this type is supported by analysis of a 1250-plot regional dataset for the NCR and mid-Atlantic national parks vegetation mapping projects. In that analysis, this association was represented by 22 plots from James City, Stafford, Surry, Westmoreland, and York counties, Virginia, and two plots from Kent County, Maryland. According to Rod Simmons, vegetation similar to the stands of this type at Crow's Nest, Stafford County, Virginia, occurs across the Potomac River at Chapman's Landing, Maryland. It is likely that this community type is endemic to a narrow region of the Coastal Plain stretching from Charles County, Maryland, south to Surry County, Virginia. Further inventory is required to determine whether it is present in Isle of Wight County and City of Suffolk, Virginia. This is a small-patch community type, usually occurring in patches of
