Following site inspections and staff inductions in April 2017, our initial works included high-volume herbicide application, targeting weeds including Kikuyu, Buffalo and Couch grasses. Following brush cutting of these grasses in preparation for mulching, herbicide application was conducted on re-emergent annuals and grasses in areas prescribed for de-compaction. Weeds targeted include Fireweed, Plantain, Fleabane, Dandelion, Buffalo and Couch. In July 2017, the site was prepared for planting:
- Sediment control measures were installed as per Shoalhaven City Council requirements;
- Ripping of existing site soil and incorporation of compost material was done in allocated areas (APZ zones) prior to mulch installation and revegetation as per restoration plan;
- Delivery, storage and spreading of compost through all designated areas as per site plan. A total of 400m3 was installed and incorporated into existing site soil to a depth of 100mm.
- Delivery, storage and spreading of 900m³mulch;
- Installation of 508 lineal metres of permanent fencing;
- Installation of 250m2 of jute mesh and coir logs into designated riparian planting areas.
Revegetation of Precinct A included a range of endemic species. A total of 24,725 units were planted, with tree guards installed around 500 trees as per the Vegetation Management Plan. Weekly watering was conducted to ensure plant survival.
A two-year maintenance program began in August 2017 that involved infill planting, targeted weed removal, and watering. To provide a flowing transition between the built, terrestrial and aquatic environments of the area, our goal is to restore and expand the existing remnant Melaleuca scrub occurring within Precinct A, as well as weeding and maintenance of the revegetated area.
