A vegetation map of Thomas Stone National Historic Site based on field surveys conducted in 2001, interpretation of aerial photography acquired in 2002, and accuracy assessment field surveys completed in 2003 and 2004. This vegetation dataset includes twelve associations (seven semi-natural types and four types of recent anthropogenic origin), as well as two modified Anderson level II categories.

These data represent a vegetation map for Vicksburg National Military Park and Vicksburg National Cemetery. The data consist of nonoverlapping polygons which represent National Vegetation Classification vegetation types, and non-vegetated land cover features. Vegetation types were classified based on analysis of plot data and supplemental observations collected on the ground from 2004 through 2010. Polygons were delineated based on interpretation of digital aerial photography flown in 2004 and terrian modeling. More detailed methodology is documented in Lea, Waltermire, and Nordman (2013).

Seabeach amaranth (Amaranthus pumilus) is a plant species that was once prevalent on beaches of the U.S. mid-Atlantic coast but is now listed as threatened by the U.S. Fish and Wildlife Service. For much of the 20th century, seabeach amaranth was absent from the mid-Atlantic coast and thought to be extinct, presumably as a result of increased development and recreational pressure. One region where there has been an effort to restore the seabeach amaranth population is Assateague Island National Seashore (ASIS), a National Park Service land holding located along the coasts of Maryland and Virginia. Here, the Natural Resources staff at ASIS planted seabeach amaranth cultivars for three growing seasons from 1999...
