Last of her tribe
- The last Sumatran rhino in Malaysia, a female named “Iman,” died on November 23,2019 at the Borneo Rhino Sanctuary in Sabah, Malaysia.
- Her death at age 25 marks the extinction of her species in Malaysia.
- Fewer than 80 Sumatran rhinos remain in the wild (in Indonesia) according to the International Union for Conservation of Nature (IUCN).
Sumatran Rhinocerous
Dicerorhinus sumatrensis
- Sumatran rhinos are the smallest of the living rhinoceroses and the only Asian rhino with two horns.
- They stand about 3 feet (1 meter) tall, measure up to 13 feet (4 m) long and can weigh as much as 2,000 lbs. (900 kilograms)
- Once it roamed as far away as the foothills of the Eastern Himalayas, Myanmar, Thailand, Vietnam, China and the Malay Peninsula.
- Today, the species only survives on the Indonesian islands of Sumatra and Borneo.
IUCN status of all Rhino species
- Five rhino species can be found today, two in Africa and three in Asia
Reasons for Sumatran Rhino’s declining numbers
- The critically endangered species was decimated by poaching and habitat loss in the past.
- Today the biggest threat to their survival is –
- small and fragmented nature of their populations,
- and a low birth-rate(1 calf in 4 years)
- Solitary nature
- Few remaining populations in the wild
- Not enough to support natural reproduction
- Isolated individuals have been found to be prone to developing reproductive pathologies like the uterine tumors suffered by Iman.
The failed captive breeding program
- Captured in 2014 and brought to a sanctuary for a breeding program, Iman suffered from uterine fibroid tumors— growths on the walls of her uterus.
- Malaysia declared in 2015 that the species was extinct in the wild, with only the captive population remaining.
- Between 1987 and 2014, Malaysia had captured over a dozen wild rhinos.
Future revival
- Conservationists have stored cell cultures from Iman.
- They hope that, when the technology is in place, these cells can be turned into viable embryos and transplanted into a surrogate
Indonesia’s efforts
- ~60-80 Sumatran Rhinos remain in the wild in Indonesia.
- Indonesia developed a plan in 2017 to capture rhinos and corral them into large, semi-natural breeding and research facilities.
The country has eight individuals in captivity:
- 7 in Sumatra, including two captive-born calves
- 1 in Borneo
Rhino Horn
- Growing consumer demand for rhino horn has driven the unsustainable increase in poaching across Africa and Asia.
- Rhino horn is coveted in parts of Asia for its purported medicinal qualities and as an ornament, which connotes social status and prestige.
- An average sized horn can bring in as much as a quarter of a million dollars in Vietnam
- The horns are made of keratin, the same type of protein that makes up hair and fingernails.
