Kirra Beach Dune Revegetation, QLD

Dune works in Kirra beach, Queensland, to maintain the beach amenity and reinforce a buffer to the shoreline, while also reinstating native plant communities along the dunes for stabilisation and the conservation of biodiversity. The site was maintained for a period of twelve months post-planting to promote good growth of installed plants, prevent weed incursion, ensure dune stability through increased native vegetation cover and assist natural regeneration of dune species. Planting survival rates at five months varied mainly due to mobile sand and anthropogenic disturbance, while at twelve months the Beach Spinifex densities approached densities expected for a naturally established frontal dune. Overall, the project met and exceeded requirements.
