Constraints & Issues

  • Degraded overstorey with some native species and a highly degraded under-story dominated by Kikuyu grass, Typha and Arum lily amongst others.
  • Some erosion and very steep slopes in some areas along the creek, which made mulching difficult.
  • The hard-landscaping works were at different stages of implementation which required the coordinated work of multiple contractors around the same area.
  • Kangaroos inhabit the site, which increased the risk of losing seedlings through grazing.
  • Dumping of rubbish and vandalism.

Our Management Approach

  • The revegetation area was 4.5 ha, which required the installation of 2,000 m3 of mulch, the planting 101,000 native seedlings, and the installation of 91,000 tree-guards.
  • Thorough weed control was conducted through the application of selective herbicides due to the sensitivity of the wetland, and also manual removal of woody weeds and Typha was necessary.
  • Tree-guards were installed to protect the seedlings from kangaroo predation.
  • Due to the coordination of works for multiple contractors, seedling planting took place at different stages from late winter through to early summer. Tranen’s flexibility and strategic thinking allowed to accommodate and consider the needs of all contractors whilst successfully achieving and delivering the high standards that the client expected.

The Outcome

The local ecosystem has been significantly improved, not only aesthetically but also functionally. The project is only in its early phases and survival and growth rates are encouraging as shown in some of the photos taken around six months post-planting.  The local residents have also benefited from additional landscaping works of the area by having easier and interconnected access to the local bushland. The project was successfully completed on time and on budget.
