The saola is the world’s rarest large mammal. It hasn’t been recorded since a trail camera captured an image of one in 2013, but it is believed that this elusive species still resides in the steep terrain of the Annamite Mountains between Vietnam and Lao – there just hasn’t been a comprehensive search for it yet.
This is the challenge being undertaken by the Saola Foundation. If it is still in Lao, they intend to find it – but time is running out.
“Even if we found one, we could learn so much. One saola teacher.”
Lorraine Scotson, Chief Executive Officer of Saola Foundation
The very idea of finding one saola holds so much hope for the team at the Saola Foundation, who are dedicated to finding one of the most elusive mammals in the world: the saola.
The status of the saola right now is critical – there could be 1-100 individuals still in the wild, spread across the vast, treacherous terrain of the Annamite Mountains. Though home to numerous species which cannot be found anywhere else in the world, it is laced with snares that have been emptying its vast forests at heart-breaking speed.
With such a small population, the chances of saola finding each other to breed successfully are now so slim, there has been unanimous agreement in the conservation community that the main priority must be a captive breeding programme – if any individuals can be found and captured.

The search
The Saola Foundation team are throwing everything they can towards their single purpose: the search for saola. They have channelled their strategy into three methods of search: DNA analysis, sniffer dogs, and human trackers.
As the ranges of individual saola – like anything known about them, carefully guessed – are thought to be very wide, trail cameras are unlikely to help the search at the speed the Saola Foundation need to find their animals. Instead, using anecdotal stories cross-checked with regions with lower levels of poaching, the team will focus on dung and tracks to try and determine where the remaining saola are.
Financial support has brought a huge advantage. New equipment allowing DNA analysis of dung in the field means the team can conduct PCR tests for saola – achieving results in an hour. Previously any samples would need to be taken out of the forest and tested. Results could take weeks, by which time the animal would be long gone.
But now, should they get a positive result, they can deploy their tracking teams straight away.
Following the signs

Working with Working Dogs for Conservation, two spaniels (Bertie and Norman) in Texas were trained in tracing tropical hoofed mammals. Due to the lack of saola samples, they cannot be trained specifically on the target species – at least, until the real thing can be found. Learning alongside the dogs was Vatsana Chanthavong, newly recruited to lead the dog handling team in Lao.
Meanwhile, another organisation Cybertracker will support the human tracking team, made up of tracker apprentices recruited from a highly competitive recruitment across communities local to the search.
“What is really exciting is that both these types of tracking, dog and human, are highly valuable in themselves, but together they give us a huge advantage.”
“Once we can integrate the teams so they can work together – dogs following the scent cues and humans tracing the visual ones – we will be able to move at speeds in the forest impossible for either approach alone. And that means we could feasibly follow an animal in real-time,” says Lorraine.
That will be essential for the next steps: observation and, eventually, capture.
