Conserving the critically endangered Tonkin snub-nosed monkey in Vietnam

Project lead: Lam Van Hoang

Fauna & Flora is building community-led conservation initiatives across critical forest habitats to protect the Tonkin snub-nosed monkey from habitat loss and hunting. 

Our work with Tonkin snub-nosed monkeys 

We have focused on community-led conservation by engaging local communities in species monitoring and habitat protection. Our work in the Khau Ca species and habitat conservation area is the first successful model of spatial-use forest management. It has demonstrated the importance of communities in establishing sustainable conservation initiatives. Fauna & Flora has also developed a species conservation action plan for these sites, and we are raising awareness about this endemic primate. 

Fauna & Flora built the Khau Ca and Tung Vai conservation field station and continues to support community-based patrol groups in Quan Ba and Ha Giang, with five patrol groups. Fauna & Flora is currently planning mitigation strategies to protect forest quality for the Tonkin snub-nosed monkey. 

Project goals 

We aim to conserve Khau Ca forest, which is home to the Tonkin snub-nosed monkey and other rare species, build capacity for partners and provide sustainable livelihoods for the local community. 

Our impact

Whilst the species is still listed as critically endangered by the IUCN, through Fauna & Flora’s work the population in Ha Giang has increased by at least 75%.
