Research overview: management units versus subspecies in tiger conservation

Conservation genetics distinguishes formal subspecies from management units and evolutionarily significant units, and this distinction is central to tiger planning. This overview explains how managers can recognize genetically distinct populations worth preserving separately without elevating them to named subspecies. It discusses how this framing can defuse the lump-versus-split debate: even under a two-subspecies taxonomy, distinct populations like the Amur or Sumatran tiger can be managed as separate units to retain local adaptation. The piece reviews how genomic data define such units and inform decisions about translocation and genetic rescue. It argues that conservation does not always require taxonomic names, and that conflating the two can either over-fragment or over-homogenize management. The concept generalizes across many debated felid taxa.
