Iām taking the keystone species list for the Great Plains ecoregion (found at https://www.nwf.org/Garden-for-Wildlife/About/Native-Plants/keystone-plants-by-ecoregion) and listing out the species that are known to be native to Douglas County, Nebraska, according to the BONAP range maps. https://permapeople.org/psyspoop/plans/native-keystone-species-of-douglas-county-nebraska-1
See how psyspoop has arranged these plants.
