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.

In the final map, 12 vegetation associations were attributed to 73 total polygons: 10 associations to 44 polygons at the Castle unit and 9 associations to 29 polygons at the Well unit. Polygons ranged in size from less than 0.5 hectares (1.23 ac, associated with numerous community polygons divided by roads and water), to 31 hectares (76.6 ac, for a stand of Canotia holocantha Shrubland Association that spans the entire eastern boundary of the Castle unit). This latter polygon accounts almost 8% of the vegetated area across the park. At the Castle unit, riparian communities covered roughly 20% (60 ha, 148 ac) of the vegetated area, including polygons attributed as water. Upland communities covered around 53% (156 ha, 385 ac), and floodplain communities covered 27% (80 ha, 197 ac). At the Well unit, riparian communities covered roughly 20% (21 ha, 52 ac) of the vegetated area, including polygons attributed as water. Upland communities covered around 63% (63 ha, 156 ac), and floodplain communities covered 16% (16 ha, 40 ac).
