Range Mapping

WYNDD maintains range maps for all species, subspecies, and varieties thought to occur in Wyoming. Our primary range mapping units are 10-digit Hydrologic Units (watersheds). For a given taxon, each hydrologic unit in Wyoming is attributed with occurrence type (regular, irregular, absent), origin, life history activities such as reproduction and migration, detectability windows, and reintroductions.

Range maps are intended to provide an overview, at the statewide and regional scale, of the general pattern of occupancy for a taxon. Range maps are informed by WYNDD's occurrence data and are regularly reviewed by statewide experts for accuracy and currentness.
