Predictive vegetation map of low-density juniper stands in SE South Dakota and NE Nebraska

The map of low-density juniper was generated using a random forests model that predicted the probability of low-density juniper (cover < 15%) as a function of seed source distance, see source density, climate, topography, and land use. The final model had an area under the receiver operating characteristic curve (AUC) of 0.884. When low-density juniper was predicted using a probability cutoff of 0.38, the resulting classification had a sensitivity of 0.71 and a specificity of 0.88.
The low-density juniper probability map is stored as the GeoTIFF file "juniper_prob_masked.tif". The classified map based on a probability cutoff of 0.38 is stored as the GeoTIFF file "juniper_lowdens_masked.tif". The dataset has a raster cell size of 30 m and is in the UTM projection, zone 14N.
