Geospatial data for the Vegetation Mapping Inventory Project of Capitol Reef National Park

Published by National Park Service | Department of the Interior | Metadata Last Checked: January 25, 2026 | Last Modified: 2009-07-01T00:00:00Z
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. Polygons representing vegetation or land use map classes were delineated on-screen in an ArcView environment. The project used the program standard minimum mapping unit of 0.5 ha with few exceptions. The 18,633 map polygons representing 70 natural and semi-natural vegetation map classes cover 134,377 ha (332,053 acres, 91.6% of the project area). Map classes representing 1,720 polygons of unvegetated bedrock, talus, wash channels or sand sheets total 11,515 ha (28,454 acres; 7.8% of the project area). Nine map classes describing 634 polygons of land use categories, including roads, ranch developments and NPS facilities, total 862 ha (2,130 acres; 0.6% of the project area). Average polygon size across all map classes is 7.0 ha (17.3 acres). The most frequent vegetation map class is the Pinyon-Juniper / Mesic Shrubs Woodland Complex (Map Class 16 / W-PJME) with 5,122 polygons covering 42,197 ha (104,271) acres or 28.7% of the project area.
