Figure 3. Extinctions and genetic erosion at historic localities across the black rhinoceros’ range and how these map onto surviving populations.

n = number of samples, H = number of haplotypes, PH = number of private haplotypes, SH = number of surviving haplotypes, SPH = number of surviving private haplotypes. Localities in red are globally or genetically extinct and those in blue are locally extinct. Only localities in black are still extant. Black arrows map shared haplotypes between locally-defined historic populations and extant populations. Red arrows, genetic erosion by extralimital introduction of the KwaZulu-Natal population; blue arrows, genetic erosion by extralimital introduction of Koakoland-Damaraland population; green arrows, reintroduction of the Zambezi Valley-Sebungwe population to South Africa.
