Geospatial data for the Vegetation Mapping Inventory Project of Oregon Caves National Monument, revised 2020

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 vegetation map consists of 267 polygons comprising an area of 1842.5 ha (4,552.8 ac) (Table 4). Average polygon size is 6.7 ha (16.6 ac). One-hundred-nineteen polygons were 100% dominated by one physiognomic vegetation class. The remaining polygons contain two physiognomic vegetation classes, of these: (1) 59 were 90% dominated by the primary physiognomic class; (2) 34 were 80% dominated by the primary class type; (3) 16 were 70% dominated by the primary class type; (4) 15 polygons were 60% dominated by the primary class type; and (5) 24 polygons had a 50/50 split between the two physiognomic vegetation class types present. Maps are produced in Universal Transverse Mercator (UTM) coordinates (NAD 83) with a 1:24,000 scale and a minimum mapping unit of 0.5 hectares (ha) (1.24 acres (ac)). This vegetation feature class was updated in 2017 to reflect the final Oregon Caves National Monument and Preserve boundary approved by the U.S. Congress on December 19, 2014, which deviated slightly from the original proposed expansion boundary and project area used in the original vegetation mapping effort.
