In the coastal forest Reserve of Son Tra in Central Vietnam, small populations of the endangered Red-Shanked Douc Langur - often described as the ‘Queen of Primates’ due to its beautiful colouring - have managed to survive a wide range of threats. In February 2026 I visited the Reserve and discovered how, thanks to the work of conservationists along with a changing culture towards wildlife conservation in Vietnam, Douc Langur populations are recovering and there is now real hope for their future.
