Field data for the Vegetation Mapping Inventory Project of Grant-Kohrs Ranch National Historic Site
2006-2007. Field data for the Vegetation Mapping Inventory Project of Grant-Kohrs Ranch 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. A preliminary list of potential vegetation types was developed from previous descriptive vegetation inventory work in the area. Spectral analysis of aerial imagery from the National Agricultural Imagery Program was used in combination with soils data to delineate the boundaries of map unit polygons with apparently similar vegetation. Because of the small total area of the park and limited number of polygons it was decided to census every polygon as to community type rather than sample a subset of polygons and conduct a supervised classification. Map unit polygons were censused by field crews in 2006; crew members assigned each polygon to a vegetation or landcover type from the preliminary list. Accuracy assessment field work in 2007 collected data at 283 sample points which were used to assess the validity of the initial map assignments.
