Small mammals in northern Australia have been rapidly vanishing for the last 30 years, and scientists weren’t sure why. Now, a major new study found feral livestock are largely to blame.

Australia’s threatened birds have declined by 59%, on average, between 1985 and 2016 based on 400,000 surveys at more than 17,000 locations according to Australia’s world-first Threatened Bird Index.
When a stream enters a culvert, the flow can be concentrated so much that water flows incredibly fast. So fast, in fact, that small and juvenile fish are unable to swim against the flow and are prevented from reaching where they need to go to eat, reproduce or find safety. Shutterstock

Our new invention tackles one of the greatest impediments to fish migration in Australia: culverts, those tunnels or drains often found under roads.
