On Monday, Malaysian authorities reported that the last male Sumatran rhino died in a nature reserve on Borneo island. Currently, there is only one female from the same species remaining in Malaysia. The male, Tam, is thought to have died from old age after he was discovered on a palm oil plantation. Efforts to breed Tam with females of the same species were unsuccessful.

Sumatran rhinos are one of five rhino species, and only one of three found in Asia. At their peak, Sumatran rhinos could be found in Bhutan, India, China, Malaysia, Indonesia, Cambodia, Thailand, Vietnam, Myanmar and Laos. They are the smallest rhino species in the world. Experts estimate that between 30 and 100 remain, with a few also living in captivity in Indonesia, and the U.S.

Like most species on the brink of extinction, rhinos have suffered from deforestation and loss of habitat. Logging, roads, urban development, farms and palm oil plantations have carved up their habitat. According to experts, the fragmentation of natural spaces is the primary threat to their population. Small reserves and wild spaces are simply not enough. Disconnected populations also make it difficult for the solitary creatures to find mates and reproduce.

“With logging, with roads for development, the patches of forest available are shrinking. Frankly it’s hard for them to find each other to mate and breed successfully,” said Cathy Dean of Save the Rhinos International.

In addition, rhinos are frequently poached for their horns and other medicinal purposes.

The International Union for the Conservation of Nature lists Sumatran rhinos as critically endangered, however Save the Rhino International believes there may still be hope for the species. According to their research, only about 20 rhinos could still provide enough genetic diversity to save them from extinction if they are able to successfully mate.
