Two Sumatran Rhinos in Way Kambas are Pregnant, New Hope for Critical Animals

Every Birth Matters to Conservation

The Sumatran rhino (Dicerorhinus sumatrensis) has Critically Endangered status on the IUCN Red List. According to the organizers' statement, the number is estimated to be no more than 80 individuals in the wild.

This animal now only remains in Indonesia, with a distribution in the Gunung Leuser Ecosystem Area, Way Kambas National Park, Bukit Barisan Selatan National Park, and East Kalimantan (Kaltim).

Sumatran rhino breeding takes a long time. The gestation period lasts around 15-16 months, while the weaning period can reach two years.

Therefore, every pregnancy becomes an important stage in the conservation program. Successful births can add individuals while supporting efforts to maintain the population's genetic diversity in the long term.

Inviting the public to get to know rhinos

The news of Ratu and Delilah's pregnancy became one of the highlights of the commemoration of World Rhino Day which was held by Taman Safari Indonesia together with YABI and the Ministry of Forestry on 3-4 October 2026.

Carrying the theme "Keep the Five Alive, Stand Together for Rhinos", this activity invites the public to get to know the five types of rhinos that still live in the world. Indonesia is home to two of them, namely the Sumatran rhino and the Javan rhino, which both have critical status.

The series of activities included discussions on conservation challenges, natural breeding, assisted reproductive technology, and the role of society in rhino conservation.
