Many new terms have come into use for intra-species groups of animals defined with genetic criteria including subspecies, evolutionarily significant units, evolutionary units, management units, metapopulations, distinct population segments, populations, and subpopulations. These terms have redundant meanings and can lead to confusion for biologists, managers, and policy makers. I propose that for wildlife management we can simplify intra-species terminology and use only the terms subspecies, populations, and subpopulations. These 3 terms have roots in evolutionary and population biology and can incorporate genetic, demographic, and geographic considerations.
