Conservation overview

The black rhinoceros is a browsing African rhino with a hooked upper lip for feeding on shrubs. It is assessed as Critically Endangered, though intensive protection has helped some populations recover.

It is generally solitary and, despite the name, is grey rather than black.

Range & habitat

Found in fragmented populations across eastern and southern Africa, including Namibia, South Africa, Kenya, and Zimbabwe.

Major threats

Threats below are drawn from the authoritative sources listed on this page. For the current, complete assessment, see the IUCN Red List.

  • Poaching for horn
  • Habitat loss and fragmentation
  • Small, isolated populations

Why it matters

As a large browser, the black rhino shapes the vegetation of African savannas, and it is a flagship for anti-poaching and protected-area efforts.

Frequently Asked Questions

What is the difference between black and white rhinos?
Both are grey; the names do not reflect colour. The black rhino has a pointed, hooked lip for browsing shrubs, while the white rhino has a wide, square lip for grazing grass.
Why are black rhinos Critically Endangered?
Published assessments point to poaching for horn and habitat loss. Numbers crashed dramatically in the 20th century, though protection has since helped some populations recover. See the IUCN Red List.
