Vegetation - Mojave Desert National Preserve [ds3128]

The data were used to classify 67 plant alliances and two landform types, ultimately identifying 136 plant associations within MOJA and CAMO. The vegetation map for the project, covering the entire 1.6-million-acre area, was created using a hybrid mapping approach that combined manual and automated techniques. The map was based on 2018 National Agriculture Imagery Program (NAIP) basemap data and was validated through ground-based verification efforts.

The accuracy of the final vegetation map was assessed at 91%, with a Kappa value of 92%, indicating a high level of reliability. The minimum mapping unit is 1.2 acres (0.5 hectares). The final products of this project include a spatial geodatabase, digital field photos, metadata, a classification report, and a field key to the vegetation alliances.

These resources provide a valuable tool for ongoing research and conservation efforts in these ecologically significant areas.
