Geospatial data for the Vegetation Mapping Inventory Project of Grant-Kohrs Ranch National Historic Site

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2007-01-01T00:00:00Z
The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. The initial vegetation mapping recognized 40 plant community types and an additional 4 landcover types, but was estimated to have an overall accuracy of less than 29%. This low initial rate was attributed to reduced repeatability from the fine scale of both the original community types as well as the very small map unit polygons enabled by the mapping methodology. Furthermore, the complexity and prevalence of cultural vegetation types at GRKO required that the revision of types consider park management requirements as more important in some cases than mapping program standards. Consequently, the original types were aggregated into 29 final map classes representing 22 USNVC plant associations
