A dairy property on the North Channel of the Manning River adjacent to Dumaresq Island had a severely modified riparian corridor with an actively eroding bank and loss of mangroves and rainforest vegetation. Bank stability was provided by installing 600 m of rock fillets to encourage mangrove and other aquatic habitat. Stock proof fencing (800 m) was installed and weed management and revegetation with native riparian rainforest species was undertaken. Completed in 2012.
