## Quick answer

The Sumatran rhinoceros (*Dicerorhinus sumatrensis*) is a mammal in the family Rhinocerotidae. Range in Indonesia: Remaining Indonesian habitat pockets in Sumatra and Kalimantan. It is endemic to Indonesia, living naturally only in Now only Sumatra and East Kalimantan; formerly also Malaysia and mainland Asia. Diet: forest vegetation; a herbivore. IUCN Red List status: Critically Endangered. It is a legally protected species in Indonesia (Regulation P.106/2018).

## A small rhino with two horns

Dicerorhinus sumatrensis differs from the Javan rhino in body form, hair, and number of horns. Calves have a thicker covering that changes with age. Both Indonesian rhinos need conservation, but their management needs and population circumstances should be understood separately.

Evidence: [WWF — Sumatran rhino](https://www.worldwildlife.org/species/rhino/sumatran-rhino/)

## The name does not define the whole range

The Sumatran rhino’s historical range extended far beyond the island in its name. Conservation sources place the remaining groups in Sumatra and Kalimantan. A photograph or report from Kalimantan therefore does not automatically concern a different rhino species; check scientific name and source context.

## When individuals are too far apart

Fragmentation can separate rhinos so opportunities to find a mate become limited. Forest presence does not by itself mean a population can reproduce. This explains why conservation combines habitat protection with specialist reproductive management, rather than simply increasing the area marked as protected on a map.

## The role of sanctuaries and research

International Rhino Foundation’s Sumatran Rhino Sanctuary account describes conservation breeding and veterinary and keeper monitoring of mothers and calves. The programme includes an insurance population for the species’ future. A sanctuary birth does not by itself establish wild recovery; habitat protection and continued monitoring remain necessary.

## Protect the future without exposing locations

Support habitat protection and programmes that explain methods and outcomes. Do not share coordinates, recent movement routes, or camera locations. Comparing Javan and Sumatran rhino profiles helps show why conservation strategies cannot simply be copied from one species to another.
