A critically endangered primate species endemic to northern Vietnam is facing threats from limestone mining and is approaching extinction, despite promising efforts at wildlife conservation elsewhere in Vietnam.
The Delacour’s langur, a small black and white monkey that lives in limestone karst forests, is one of many primates in Southeast Asia that has seen its habitat decimated in recent decades due to deforestation for agriculture and infrastructure. Three of the 25 most endangered monkeys in the world have been found only in Vietnam, according to a 2015 report. There are likely less than 300 Delacour’s langurs left in the world, all of them in Vietnam.
