National Forest region and names from the USDA S_USA.BasicOwnershipFS (Surface Ownership Parcels) attribute table. An area depicted as surface ownership parcels dissolved on the same ownership classification
A dataframe with 2 columns, R1 and FORESTNAME.
## ALP National Forest boundary alp_dsn <- "S_USA.BasicOwnershipFS.gdb" alp_layer <- "BasicOwnershipFS" alp.att <- "FORESTNAME" alp_bnd <- spImportSpatial(dsn=alp_dsn, layer=alp_layer) alp_names <- unique(sf::st_drop_geometry(alp_bnd[, c("REGION", "FORESTNAME")])) alp_names <- alp_names[order(alp_names$REGION, alp_names$FORESTNAME),] alp_names <- alp_names[grepl("National Forest", alp_names$FORESTNAME)==TRUE,] alp_names$FORESTNAME <- sub(" National Forest", "", alp_names$FORESTNAME)
Ownership classes that are not USDA Forest Service were removed from the
layer.
