Geospatial data for the Vegetation Mapping Inventory Project of Herbert Hoover National Historic Site

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.

A total of 188 acres (76 hectares) were within the accepted boundaries of HEHO. The standard minimum mapping unit for NPS vegetation inventory projects is defined as 0.5 hectare, although several mapped polygons were smaller for HEHO. Restored tallgrass prairie made up most of the current vegetation of the park, and accounted for 71.6 acres (29 hectares) in nine polygons, or 58.0% of the total non-developed area. Pasture and old field made up 38.9 acres (15.7 hectares), or 31.6% of the area, in a single polygon. Forb ruderal herbaceous vegetation made up 7.4% of the area in four polygons, and bottomland ruderal woodland made up 2.8 acres (1.1 hectares), or 1.1% of the area. Reed canarygrass, western herbaceous vegetation made up <1% of the area, and within the context of the vegetation of HEHO, is considered an undesirable, non-natural vegetation type. A total of 25 polygons were mapped, with an average area of 7.52 acres (3.04 hectares).

Minimum Mapping Unit = 0.5 hectare Minimum Patch Size=.006 hectares Total Size = 25 Polygons Average Polygon Size = 7.52 acres (3.04 hectares) Overall Thematic Accuracy = 98.7% Project Completion Date: 12/2013
