Nobody knows how many Sumatran rhinos are left: the last estimate, 34 to 47, dates from March 2022 and is carried forward unchanged by the IUCN SSC Asian Rhino Specialist Group with TRAFFIC.

The last estimate, 34 to 47, dates from March 2022 and has been carried forward unchanged since.

How it was counted

The estimate is of animals across the species' only remaining range (Sumatra and Kalimantan, in Indonesia), and the 2025 report carries it forward from an earlier report to CITES. In captivity there are 11 animals, and the report does not say whether the 34 to 47 includes them.

An estimate with a range, not a count of every animal: about 34 to 47, where 34 is the low end and 47 the high end.

What moves it

The IUCN SSC Asian Rhino Specialist Group with TRAFFIC names poaching for the horn trade as the largest threat to rhinos as a whole (African and Asian), not to this species alone.

The next count

No date for the next count is known as of 12 November 2026; the schedule is irregular (reported to each CITES CoP).
