Vietnam's Rare Monkey Population Triples!
19 May
Summary
- Critically endangered Tonkin snub-nosed monkey population more than tripled.
- 80% of the species now lives in Vietnam's Khau Ca reserve.
- Conservation efforts include patrols, community engagement, and fuel-efficient stoves.

The population of the critically endangered Tonkin snub-nosed monkey in Vietnam's Khau Ca reserve has seen a remarkable increase, more than tripling to 160 individuals since 2002. This surge now accounts for an estimated 80% of the entire species, a testament to successful conservation initiatives.
These shy, elusive monkeys, endemic to Vietnam, were once thought to be extinct due to hunting for traditional medicine and bushmeat. However, conservation groups established field stations and community teams to patrol forests, remove snares, and report illegal activities. To support local communities, new income streams, such as patrol groups, were created.
A recent comprehensive survey in October and November 2025, involving over 30 people across 1,000 hectares, utilized advanced methods like thermal imaging drones and acoustic sensors. This contrasts sharply with Quan Ba, another former habitat where the monkeys have not been sighted since 2020, largely due to cardamom farming clearing forests.
Conservationists are now working to create wildlife corridors to connect Khau Ca with Quan Ba, aiming for broader habitat restoration and protection for this unique species and other wildlife. The efforts in Khau Ca offer a promising model for the species' long-term survival.
