Donor material from on-site salt couch (Sporobolous virginicus) and samphires (Halosarcia pergranulata, Halosarcia indica, Sarcocornia quinqueflora) was harvested, propagated off-site and transplanted back to site once grown. A large portion of salt couch was extracted from the Wangi Way drainage reserve. Turf squares removed from this area were transplanted into the site. Only plants free of disease and insect pests, with a vigorous growth habit and good quality and colour of foliage were harvested.
Bushcare Services aim to re-profile tidal landform, manage invasive weeds, trap and harvest mangrove seeds and rebuild the original flora composition to levels of pre-disturbance. Non-commercial plant species are being custom grown off-site for re-introduction – post works. Mangrove seed and silt traps are currently highly successful in creating opportunities for recent mangrove seed drops to regenerate in previously disturbed sections.

• Transplanting mangrove propagules to disturbed areas and gabions.
• Propagating 10,000 pots of saltwater couch and samphire for replanting.
• Control of invasive weeds including Groundsel and Broadleaved pepper. Removal of mature pine trees from site.
• Mulching, cutting and planting native pockets.
