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.
Mangroves
Method: Hybrid, Supplementary revegetation, Rehabilitation
Rehabilitation - method: Grazer control
Supplementary revegetation: Riparian trees and Lomandra sp., stabilised with jute mesh
Hybrid structure: Rock-fillets, Offshore structure - wood (hardwood stumps, hardwood pins)
Hybrid structure height (m): 1m (rock fillets), 2m (wood pins)
Hybrid structure width (m): 2m (rock-fillets), 200mm (wood pins)
Hybrid structure length (m): Rock-fillets: root wads every 5 m, timber pin every 1 m, key rock-fillet into bank 0.5 m
