Hastings River, NSW

Recycled highway materials, tree slumps and timber pins were incorporated in rock-fillets to protect the eroding bank and expand intertidal habitat. In the riparian zone, native riparian trees were planted and established fences to exclude stock access. Lomandra were also established in jute mesh along the bank edge.
