Field data for the Vegetation Mapping Inventory Project of Gettysburg National Military Park and Eisenhower National Historic Site

This reference is an assemblage of field data collected as part the baseline vegetation inventory for the park unit. Typical files here are vegetation plot data, accuracy assessment data, field photos, PDF showing locations of vegetation plots and accuracy assessment data, and other data for this type. Plot sampling was conducted from May through August 2004. The diversity of vegetation types was significantly less than originally estimated; therefore, not all 112 vegetation plots were necessary to accurately capture the natural range of variation of the vegetation types in the parks. At the conclusion of plot sampling, 70 plots were sampled and observations were recorded for 81 additional polygons. Eight plots fell within the boundary of Eisenhower National Historic Site. Data from the 70 vegetation plots were entered into the NatureServe PLOTS 2.0 Database System on a Microsoft Access platform during September 2004. In the PLOTS 2.0 database, species were assigned standardized codes based on the PLANTS Database, Version 3.5, developed by the Natural Resource Conservation Service in cooperation with the Biota of North America Program. From July through September 2005, each accuracy assessment point was located in the field. The accuracy assessment data form used in this study is shown in Appendix E. Data from the 227 accuracy assessment points were then entered into the NatureServe PLOTS 2.0 Database System on a Microsoft Access platform during September 2005.
