In 2015 a mass mortality event struck the highly range restricted Bellinger River Snapping Turtle (Myuchelys georgesi), wiping out 90% of the species in under six weeks. The initial emergency response included site examinations, removal of dead and sick animals, and a water quality investigation. Bellinger River Virus (previously unknown to science) was eventually identified as the causative agent. To better understand the circumstances behind this mass mortality event, a One Health approach was taken addressing how the animals, causative agent, and surrounding environment interacted with each another. A facilitated multi-stakeholder conservation planning workshop was held incorporating the IUCN SSC/OIE’s Wildlife Disease Risk Analysis process (Jakob-Hoff et al, 2014). This ensured all potential contributing factors associated with the Bellinger River Virus outbreak were reflected in immediate and long-term priorities and on-ground recovery actions.
