[1] The park extends to the south of the Save River in Inhambane Province, covering an area of 4,000 square kilometres (1,500 sq mi).

Species that are locally extinct or close to extinct include black rhinoceros, Cape buffalo, cheetah, reedbuck, eland, elephant, giraffe, Lichtenstein's hartebeest, roan antelope, sable antelope, spotted hyena, wildebeest and Selous' zebra.

The riverine forest is found on the banks and levees to the south of the river, with diverse trees reaching heights up to 20 metres (66 ft).

Further from the river is Acacia nigrescens woodland, covering 10.5% of the PNZ, merging into mopane and miombo landscapes in the south.

The mopane landscape is found on heavier soils and covers 37.5% of the park, dominated by mopane-dominated closed woodlands.

A sandveld landscape, consisting of open woodlands on deep reddish sandy soils, covers 16.7% of the park.

Finally, the miombo landscape covers 29.5% of the park in the higher, wetter southeastern section and includes open grasslands and wetlands.
