\Data\Spearfish_1ha_shrub_skids.csv: Comma-delimited ASCII text file containing XY coordinates for the vertices that make up the polygons representing shrub patches, skid trails, and areas with bare ground (exported from the corresponding shapefile: \Data\GIS\poly_features.shp) for the 1 hectare (ha) study plot. Variables in this file are defined below.
FID = Standard ArcMap unique identifier for each vertice
AREA = Area of associated polygon (square meters)
PERIMETER = Perimeter of associated polygon (square meters)
POLY_FEA_1 = Unique identifier before being placed into ArcGIS
