The dunes experienced a 70% die-off of Alyxia buxifolia, the dominant plant species. Revegetation was needed to restore the dunes' biodiversity. Biodegradable guards and tree guards as well Cocoon Aid incubators were used to assist revegetation success. Increased erosion control as a result of the revegetation was a co-benefit of the habitat restoration work.
