The National Park Service (NPS) National Capital Region (NCR), the Virginia Natural Heritage Program (VANHP), NatureServe, and Natural Heritage Programs in Maryland, Pennsylvania, and West Virginia, completed the vegetation classification and mapping of eleven parks, totaling 29,968 hectares (74,053 acres) in the NPS NCR. Upon the completion of the vegetation characterization and mapping, NatureServe finalized this process by conducting a thematic accuracy assessment of the resulting the vegetation map. Field observations were collected at 1,561 locations across the eleven parks to analyze the map classes observed in the field against those on the map. Overall map accuracy for 66 map classes was 80.59% (Kappa statistic of 79.23%). The final vegetation maps included a total of 110 map classes that were used to characterize 109 USNVC associations plus other land cover across the 11 parks. These 110 map classes can be separated into four categories: individual USNVC associations (n=80), composite map classes primarily comprised of another 30 USNVC associations (n=11), special feature map classes (n=9), and National Land Cover Database map classes (n=10). Of the 109 USNVC associations, 106 were identified during the classification effort and three were added during the mapping effort; 55 represented upland and 54 wetland or riparian vegetation.
