Selous Game Reserve's heritage significance lies in its Outstanding Universal Value (OUV) as one of Africa's largest protected areas (51,200 km²), serving as a global laboratory for ecological processes under UNESCO natural criteria (ix) and (x).
It boasts exceptional biodiversity with the continent's largest elephant and wild dog populations, black rhinos, Nile crocs, hippos, plus 350+ birds in diverse habitats like miombo woodlands, floodplains, and swamps—relatively undisturbed for in-situ conservation. Inscribed in 1982 (ref. 199), it embodies pristine miombo ecosystems and predator-prey dynamics within a 90,000 km² Selous Ecosystem linked to Mozambique's Niassa Reserve.
