Colonial National Historical Park
Appendix D. Distribution of vegetation classes, derived from the analysis of regional
quantitative plot data, across seven national parks in Virginia.
Vegetation was classified and mapped in seven national park units in Virginia: Appomattox
Court House National Historical Park (APCO), Booker T. Washington National Monument
(BOWA), Colonial National Historical Park (COLO), Fredericksburg and Spotsylvania National
Military Park (FRSP), George Washington Birthplace National Monument (GEWA), Petersburg
National Battlefield (PETE), and Richmond National Battlefield Park (RICH). The classification
used to map these parks was developed regionally, using quantitative data that were collected
from all seven parks and combined with existing data from throughout the Mid-Atlantic
Piedmont and Coastal Plain. Quantitative analysis classified 35 associations occurring in the
seven parks. An additional 19 associations and 12 nonstandard, park-specific vegetation classes
representing disturbed, cultural, or exotic vegetation were also recognized from the seven parks,
but were not represented by quantitative data. The relationship of all vegetation classes to the
map classes used to map Colonial National Historical Park can be found in Table 11 of the main
report. Vegetation classes listed with USNVC codes are equivalent to associations in the United
States National Vegetation Classification (NatureServe 2007). Global and State conservation
ranks are defined in Appendix E.
