Scientists have discovered a previously unknown population of Miller's grizzled langurs (Presbytis hosei canicrus), an endangered primate thought to be on the verge of extinction. The rare langurs were discovered in the Wehea Forest of East Kalimantan, Borneo. Wehea Forest is a 38,000 hectare patch of undisturbed rainforest that is home to nine species of primates including gibbons and the Bornean orangutan.
Since 2004, scientists have been concerned that Miller's grizzled langurs had become extinct. A survey conducted in 2008 found none of the langurs, further supporting the possibility that the species had become extinct. Fortunately, camera traps set up in areas west of the Miller's grizzled langur's range revealed that the species was still living.
Since the Wehea Forest is remote, it presents challenges for scientists hoping to study the animals that inhabit the area. Consequently, not much is known about Miller's grizzled langurs. Any effort to protect the species will be clouded by a lack of knowledge and understanding of the species habits and even their range.
