John Woinarski, Sarah Legge and Chris Dickman have been engaged for many decades in research, management and policy relating to biodiversity across Australia, with an enduring commitment to the conservation of Australia's fauna. All three authors are affiliated with the Threatened Species Recovery Hub of the National Environmental Science Program. This book is motivated by the authors' interest in the factors causing decline in Australia's remarkable fauna, their recognition of the need to communicate this conservation challenge to our community and to promote solutions to the loss of biodiversity.
