Building on trials in Altona, Grantville and Lang Lang, 148 mangrove planters were installed at Jem Jerrup in 2022, and direct seeded with Avicennia marina. The hybrid mangrove erosion control was installed alongside a rock revetment placed at the base of an eroding cliff and aims to build the resilience of the unarmoured shoreline. Monitoring has been funded until 2024 and will be investigating the effect of the planters on mangrove survival, sediment accretion and wave attenuation. Yearly mangrove planting will be done throughout the study period.
