Khau Ca

In the remote northern limestone formations of Vietnam’s Ha Giang Province, a small area of forest called Khau Ca is home to the largest population of Tonkin Snub-nosed Monkeys in the world, ~115 individuals.

This 1,000 hectare area is dominated by lower montane evergreen limestone forest, and is one of the most pristine and intact examples of this rare forest type remaining in Vietnam. Along with the TSN Monkey, researchers have reported the presence of 16 animal and 29 plant species recognized as nationally or globally rare and threatened. Though the faunal biodiversity of Khau Ca has not been particularly well studied, 33 mammal, 153 bird, 12 reptile, and 2 amphibian species have been recorded within the forest, and many more are suspected to live there. Protecting Khau Ca is the best method of ensuring the long-term survival of the TSN Monkey and countless other rare species.

Since 2014, the New Nature Foundation has been very excited to be partnering with the Denver Zoo in a new endeavor to increase fuel efficiency in the communes surrounding Khau Ca, thereby helping to safeguard this last refuge for the Tonkin Snub-nosed Monkey.
