Can excluding toads from water provide biodiversity benefits for arid Australia?
A project undertaken at the School of Biological, Earth & Environmental Sciences, University of New South Wales, and supervised by Mike Letnic
Our research has shown that excluding toads from dams can suppress their populations. In this project, we are also comparing whether water storage tanks, used as an alternative to dams, can effectively limit toad numbers and their impacts on a fauna, particularly, goannas. Tanks support fewer toads than dams, because there is less water available for toads to rehydrate.
