This landcover raster was generated through a Random Forest predictive model developed in R using a combination of image-derived and ancillary variables, and field-derived training points grouped into 18 classes. Overall accuracy, generated internally through bootstrapping, was 75.5%. A series of post-modeling steps brought the final number of land cover classes to 28.

These data cover designated National Wildlife Refuges (NWRs) in Montana. They are extracted from the statewide land ownership and managed areas layer maintained by the MTNHP.

The name of each Refuge is provided in the NAME attribute field.
