00:02This pool-connected wetland on the River Murray has been transformed by the local
00:07landscape board.
00:09The waters of Teal Flat Hut are now rich with plants and native wildlife, and free
00:15of destructive European carp.
00:17When you come out and have a look at a wetland like this, it never ceases to blow you away.
00:23It's absolutely phenomenal, the response you get.
00:26The scientists shut the wetland off from the river, and the water in the ponds evaporated,
00:31killing the carp.
00:33Fitted screens allow native fish and aquatic fauna to move back into the river, but they're
00:38closed when it's refilled with water to stop large carp getting in.
00:43Now it's hoped the sanctuary can host reintroduced species wiped out during the Millennium drought.
00:49We've got an amazing array of aquatic vegetation, from ribbonweed to redwater milfoil, which are
00:54supporting an array of different species, from fish to birds to frogs to turtles.
01:00Since 2016, the federal government has spent more than $10 million researching a carp herpes
01:06virus as a biological control method.
01:09With further research due by 2028, fishers and conservationists want more carp management.
01:15So there's a real sense of frustration, but also a sense of optimism about what we can
01:20do together.
01:20The success in excluding carp at Teal Flat is adding to the optimism.
01:25There's a lot of interest in the upstream states in looking at the case studies we have
01:29here and seeing how they can be applied at different scales upstream.
