Setting conservation priorities in the Annamite mountains of Laos and Vietnam
The exceptional biodiversity and endemism of the Annamite region of Vietnam and Laos is threatened substantially by illegal hunting. We use state of the art systemic biodiversity surveys and statistical models to identify the last strongholds of wildlife.

Globally mammalian biodiversity is declining at an alarming rate as a result of widespread habitat loss and degradation, and unsustainable hunting. Since 2014, we have worked in the Annamite mountain range of Vietnam and Laos. This ecoregion is a global biodiversity hotspot with an exceptionally high concentration of endemic mammals. However, its terrestrial mammal communities are highly threatened by illegal hunting using wire snares. Industrial-scale snaring has resulted in largely defaunated landscapes, and all Annamite endemics are threatened with extinction.
We implemented systematic camera-trapping and invertebrate-derived DNA surveys across a suite of sites, including both protected and non-protected areas, across the Annamites. A major focus of our work is to better understand the ecology and distribution of little-known but threatened Annamite endemics. To do this, we use advanced species distribution models to map mammalian biodiversity at landscape-scales, thus helping to identify the last strongholds for threatened Annamite species. In all of our work we collaborate closely with local conservation stakeholders and decision makers in order to integrate our results directly into wildlife and conservation management.
