NDO – Forty-Four different primate species call the Greater Mekong home, with 25 of these found in Vietnam. But these unique species are increasingly threatened by habitat loss and fragmentation, climate change, and hunting driven by consumption and illegal trade.

The World Wide Fund for Nature (WWF) released a report “Primates of the Greater Mekong: Status, Threats and Conservation Efforts”, on January 1.

The new report highlights the amazing diversity of lorises, macaques, langurs and gibbons, that live in the five Greater Mekong countries - Cambodia, Laos, Myanmar, Thailand, and Vietnam.

The profiled species include the skywalker hoolock gibbon, which was described as a new species in 2017, and the Popa langur which was only described as a new species in 2020. The 44 primate species found in the region, among which 19 are endemic, is a testament to the amazing biodiversity of the region, but their conservation status is a stark reminder of the grave threats they face.

Deforestation, habitat degradation and hunting, driven by the wildlife trade and consumption, have forced many primates in the Greater Mekong to the brink of extinction. One quarter of the species are classified as Critically Endangered on the IUCN Red List, while about half are categorised as Endangered.

Vietnam is home to five endemic primate species, all of which are included on the list of the worlds’ 25 most Critically Endangered species. Moreover, the latest Red List assessments show an increased extinction risk for a quarter of the primates, compared to the previous assessments conducted in 2008, while the rest showed no reduction in their extinction risk.

Their meat is sold as food, parts are traded for use in traditional medicine, and live animals are marketed as exotic pets or props for tourist selfies. The number of primates in the legal wildlife trade - often for use in biomedical research and pharmaceutical testing - has been on the increase, with the legal trade in primates estimated to be worth 138 million USD in 2015.

Furthermore, research has predicted that all apes, Asian and African monkey species are at high risk of contracting SARS-CoV-2, the virus that causes COVID-19 in humans. Zoonotic diseases - which have their origins in animals and are often caused by the frequent and unsafe contact between wildlife and humans in the trade - can then be transmitted back to animals, further threatening their survival. Rhesus macaques and long-tailed macaques, both of which occur in the Greater Mekong region, were infected with the SARS-CoV-2 virus in laboratories and developed COVID-19 symptoms similar to humans.

Fortunately, many organisations, government agencies and local communities are working tirelessly to protect some of these unique species from disappearing. WWF is carrying out surveys in some protected areas to monitor primate populations, such as the white-handed gibbons in Laos’ Nam Poui National Protected Area, or the Ha Tinh langur in Thach Hoa district, Vietnam. WWF supported patrols in Vietnam and are removing snares and releasing primates caught in traps back into the wild, in the Truong Son range area.

Connecting fragmented forests and improving forest quality has also been a strategy that the WWF has carried out in Vietnam, to protect species over the past 30 years. Recently, WWF supported the upgrading of Song Thanh from a Nature Reserve to a National Park, established two new Saola Nature Reserves in Quang Nam and Thua Thien Hue provinces, and assisted government partners to extend protected areas in Quang Nam, Quang Tri and Thua Thien Hue provinces. All of these efforts are to establish safe corridors for species to thrive.

Community awareness raising activities about wildlife and primates are regularly carried out in communities that live close to the species’ habitats, as well as other key stakeholders at the national level. Besides providing conservation knowledge, WWF’s campaigns in Vietnam also encourage public changes in behaviour and engage local communities to protect their primates.

There are many other conservation organisations protecting, researching, rescuing and restoring the unique primates throughout the region. Fauna and Flora International is working extensively in Vietnam and Myanmar to monitor and protect threatened primates in key locations. The Endangered Primate Rescue Centre in Cuc Phuong, Vietnam, is rescuing and working on breeding threatened species, to reintroduce them to the wild. The Little Fireface Project is researching lorises in the wild, while also working to tackle their trade as pets and props for selfie-tourism. Organisations like the Jahoo Gibbon Camp in Cambodia and the Gibbon Experience in Laos are creating safe ways for tourists to see and hear primates in the wild, with a goal to improve local economy, livelihoods and in turn reduce hunting pressure.

“If the remaining primate populations in the Greater Mekong are to survive and eventually recover to viable numbers, governments, NGOs, corporations and local communities must all work together and implement conservation measures targeted at primates,” said Thinh Van Ngoc, CEO of WWF-Vietnam. “WWF is currently working with other primatologists to review primate conservation efforts in Vietnam; there is hope to save these incredible species that make our region unique, but we must act swiftly and decisively.”.
