The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for Arches National Park. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles.

Thirty-one (30 polygon and 1 point) natural and semi-natural vegetation map classes were developed for the ARCH mapping project, represented by 6,709 map polygons. Twelve land use map classes describe 193 other polygons within the mapping area. An additional 222 polygons represent exposures of two unvegetated geologic formations. Average polygon size across all map classes is 7.3 ha (18.0 acres). Natural and semi-natural vegetation classes cover 52,521 ha (124,171 acres / 95.6% of the project area). Map classes representing unvegetated bedrock total 1,295 ha (3,200 acres / 2.5% of the project area). Land use/land cover polygons, including roads, commercial developments, mining facilities and NPS facilities total 1,010 ha (2,497 acres / 1.9% of the project area). The most frequent vegetation mapping unit is Blackbrush Shrublands (Map Class 10 / S-BLAC) with 1,457 polygons covering 9,073 ha (22,407 acres) or 17% of the project area.
