This project involved the staged rehabilitation of an eroding riverbank at Emigrant Creek, a tributary of the Richmond River, approximately 7km upriver from the ocean. Beginning in 2007, rock fillets and embedded timber snags were installed to encourage mangrove and saltmarsh regeneration. After each stage of the installation, mangroves and saltmarsh communities quickly colonised and established, successfully stabilising the riverbank.
