Acadia National Park Vegetation Mapping Project - Field Plot PointsEntry ID: USGS_NPS_AcadiaFieldPlots
Abstract: ABSTRACT: The U.S. Geological Survey Upper Midwest Environmental Sciences Center (UMESC) has produced a vegetation spatial database coverage (vegetation map) for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (VMP). In support of mapping and classifying the vegetation, vegetation sample plots were collected and analyzed, identifying 53 National Vegetation ... Classification System natural/semi-natural associations (vegetation communities). Local botanists, via contract with The Nature Conservancy, collected 179 vegetation plot samples at Acadia National Park (NP) during the 1997-1999 field seasons. Maine Natural Areas Program performed ordination analysis using the field plot data and other existing vegetation data of the area. Vegetation communities of Acadia NP are defined and described at the local and global scale. All 179 vegetation plot samples are represented in the Vegetation Field Plot Spatial Database with selected data fields from the Project's PLOTS database.
Purpose: PURPOSE: The Vegetation Field Plot Spatial Database provides spatially referenced locations of vegetation plot samples that were collected to support the vegetation classification for the Acadia National Park Vegetation Mapping Project, USGS-NPS Vegetation Mapping Program (see Cross Reference at the end of this section for more information on the vegetation map, Project, and the VMP). This ... metadata report supports not only the Vegetation Field Plot Spatial Database coverage, but also exported database sets (dBASE IV) from the Project's PLOTS database of physical descriptions and species listing for each vegetation sample, and an overview of sampling methods and analysis. For more documentation on the analysis methods and results, including the ordination process, see the Project's technical report.
SUPPLEMENTAL INFORMATION: The Vegetation Field Plot Spatial Database is a geo-spatial point coverage. Item information within the spatial point coverage includes: ArcInfo default items, plot number, classified community name (NVCS association), provisional community name (synonym name of association), NatureServe's Community Element Global code (CEGL), date of field collection, X-Y (Easting-Northing) coordinates projected in Universal Transverse Mercator, Zone 19 with datum in North American Datum of 1983, U.S. Geological Survey 7.5-minute quadrangle names, and a comment field describing general location. --- The dBASE IV spreadsheet representing physical descriptions (exported from the Project?s PLOTS database) contains all items of the physical field data collected for each sample. In addition to those listed in the spatial database, the spreadsheet provides air photo, sublocation, quad code, X-Y coordinates, surveyors, plot shape, ground photo info, representation, environmental factors (elevation, slope, aspect, topology), topographic position, surficial geology, hydrology (Cowardin wetland, regime), environmental and landscape comments, various soil features, numerous plant physiognomic features, disturbance comments, and other comments. --- The dBASE IV spreadsheet representing species listing (exported from the Project's PLOTS database) contains a listing of all plant species recorded for each sample. The spreadsheet provides plot code, plot species counter, plant symbol, scientific name, common name, family, specimen number, used plants, source, within plot, stratum sort, stratum, diagnostic, range cover, real cover, other measures, dbh, update, and user. --- Complete data for all vegetation samples are preserved on hard copy data sheets, and digitally within the Project's PLOTS database. --- The spatial database is available, both in ArcInfo Export (.e00) and Shapefile formats, on the Project's CD-ROM.

SPATIAL DATA ORGANIZATION INFORMATION
Indirect Spatial Reference: Acadia National Park, the first national park to be established east of the Mississippi, is located on the coast of Maine primarily in Hancock County (with outlying areas in adjacent Knox County) and is situated on a large portion of Mount Desert Island as well as some adjacent mainland and island tracts, including the Schoodic Peninsula and Isle au Haut. The Park encompasses almost 48,000 acres of granite-domed mountains, woodlands, lakes and ponds, and ocean shoreline with nearby towns and villages including Bar Harbor, Northwest Harbor, Southwest Harbor, Seal Harbor, Bass Harbor, and Isle au Haut.

Quality All point features are unique with their own site attribute and X-Y (Easting-Northing) coordinates. There are no duplicate points.
All 179 vegetation plot samples are included in the spatial point coverage. X-Y coordinates are projected in Universal Transverse Mercator, Zone 19, with datum in North American Datum of 1983.
X-Y coordinates of field data locations were collected using a Rockwell Precision Lightweight GPS Receiver (PLGR). Most points were successfully collected with positional accuracies ranging from +/- 6 to +/- 10 meters.
