John Woinarski has been involved in research, management, advocacy and policy relating to biodiversity conservation, particularly in relation to threatened species, in Australia since the 1970s. Much of this work has been undertaken in northern Australia, with a particular focus on threatened mammal species, but his research and management has also considered plants, invertebrates, birds, reptiles, the impacts of fire, pastoralism, forestry, mining and invasive species, monitoring, survey design, Indigenous land management, reserve design, translocations, and islands. This work has been recognised with the Eureka Prize for biodiversity research (2001), the Serventy Medal (for lifetime contribution to Australian ornithology) (2001), the Northern Territory Chief Minister’s Award for Research and Innovation (2008), and the Australian Natural History Medallion (2012). Until 2011, he was executive director of the biodiversity division of the Northern Territory government’s environment department, but then moved to Christmas Island. From 2003 to 2012, he was a member of the Threatened Species Scientific Committee, which provides advice to the Australian minister for the environment on conservation issues relating to threatened species. He is currently employed part-time as Professor in the Research Institute for the Environment and Livelihoods, Charles Darwin University, and within the North Australian Hub of the National Environmental Research Program.
