Is there hope for the Sumatran rhino?

Blog 7 - Rhino Stationery

The Sumatran rhino (Dicerorhinus sumatrensis) is the world’s oldest surviving rhino species but with an estimate of less than 80 left, their future is looking bleak. Conservation efforts, such as the breeding programme at the Sumatran Rhino Sanctuary in Indonesia’s Way Kambas National Park, are crucial if the species is to survive.

Almost a decade ago...

In the summer of 2015 this article on Mongabay.com gave us an insight into the birth of Andatu, the plight of the Sumatran rhino and the efforts underway to save the species:

In 2012, a ray of hope was born at the Sumatran Rhino Sanctuary, in the form of a baby male called Andatu. Andatu is particularly special being the first rhino born in the sanctuary and only the fourth born in captivity in the past 100 years.

Sumatran rhinos have a unique breeding behaviour, which makes breeding in captivity difficult. A female Sumatran rhino is only receptive to mating during a single day of her oestrous cycle, which if successful results in a gestation period of 15-16 months. The calf then remains reliant on the mother for the first several years of its life, through which the mother is usually restricted from breeding with a male.

It is important to maintain focus on the wild Sumatran rhinos, the majority of which are found in three parks in Sumatra: Bukit Barisan Selatan, Gunung Leuser National Park and Way Kambas; and in Indonesian Borneo. Unfortunately, none of these three populations are connected and each is split into smaller subpopulations that are less resilient to poaching effects.

An ideal solution would be to create habitat corridors to connect the populations and encourage breeding. Conservationists believe this may not be possible due to high rates of deforestation caused by the palm oil industry and increasing human populations and development. The alternative method would be the consolidation of these rhinos into two or three large populations, a method that has proven successful in other wild rhino species. To do this a more accurate population estimate is required, but this is made challenging by the rhinos’ elusive and shy natures as well as limited funding for the survey work required.

On the brighter side, there is evidence that Sumatran rhinos are still breeding in the wild, and a decision has been made to employ more rangers to increase protection against poaching. Conservation is always a slow process, but with continued support for this unique rhino species it may be possible to prevent it from disappearing forever.

And in the last 2 years...

With the help of grants from partners and donors, the Sumatran Rhino Sanctuary has been able to improve facilities. In 2019, 14 new dorm rooms were constructed for the team, each with improved ventilation, better bathroom access and hot water throughout (the old accommodation block had no have access to hot water and the rooms had very little ventilation, which is very tough considering the humid, jungle environment).

Donations have helped provide the Sumatran Rhino Sanctuary with new veterinary items, including a biochemistry scanner and urinalysis machine to improve rhino health and fertility monitoring, as well as essential rhino medicines and supplies for treatment.

Given the importance of veterinary care at the Sanctuary – both for everyday care and for fertility healthy – it is critical that laboratory and veterinary equipment is effective. new laboratory equipment at the Sanctuary will help vets care for the resident rhinos and boost breeding success.

The Sanctuary is home to the only reproductively-viable, captive population of Sumatran rhinos in the world, currently hosting seven rhinos: four females: Rosa, Bina, Ratu and Delilah, and three males: Andalas, Harapan and Andatu.

It is hoped that this tiny group hoped will, one day, help to repopulate selected National Parks within the Sumatran rhino’s range. The upgrades to the Sanctuary’s facilities are helping everyone be more effective as they strive to achieve this goal.

Save the Rhino International is helping to support efforts to save the last Sumatran rhinos by funding Rhino Protection Units in Sumatra, as well as the Sumatran Rhino Sanctuary.
