Overview of Piney Point Tract Anthropogenic Communities/Land Covers

Five anthropogenic communities/land covers fill the Piney Point Tract, three of which, were not present in 1937 (Figure 1, Table 1). All of them, except for agricultural field, have gained in area since 1937. Going from 2002 the trends are mixed.  Agricultural, impervious surface and modified land have all gained in the recent period (2002-2012).  Semi-impervious surface has lost area.  In general, anthropogenic communities/land covers have lost area, both recent and historical.
