After trekking the leech-ridden jungle from dawn to dusk for days on end, exhaustion was starting to show on the conservation team’s sweaty faces and damp gear.
Midway into a 10-day field assignment in Vietnam, the team had no more than two good photographs of the critically endangered grey-shanked douc to show on their long-range cameras. They needed a lot more.
Such is the elusiveness of the rare monkey – even the experts have a hard time trailing it.
The grey-shanked douc can only be found in the remote forests of Vietnam’s Central Highlands. Until the recent discovery of a new population of 500 doucs by a survey team from Fauna & Flora International, the species was believed to have as few as 800 remaining in the wild.
Visible snare lines and the absence of gibbons and larger mammals in the jungle point to heavy hunting in the past, said Mr Jonathan Eames, who leading a photography and book project on the primate.
