- Summary:In 2013 revegetation was undertaken on three high conservation value wetlands at Honeywood Estate in Wandi. Over 102,000 native seedlings were planted, and extensive weed management undertaken across the 18 ha site. The project exceeded all of the success targets, and was completed on schedule and handed over to the City in 2016.
These works helped Honeywood Estate win the 2017 UDIA WA Environmental Excellence award.
In 2011 Tranen was commissioned to prepare and implement a Revegetation Masterplan for several conservation category and resource enhancement wetland conservation areas and their buffers within the Honeywood subdivision.
Constraints & Issues
- Two Conservation Category Wetlands (CCW’s) and one Resource Enhancement Wetland (REW).
- Potential habitat for the endangered Carnaby’s (Short-billed) Black-Cockatoo (Calyptorhynchus latirostris).
- A dieback infested area was identified in the northern portion of the subdivision.
- Rabbits were abundant in and around the wetland areas.
- The wetlands were used regularly by pedestrians, horse riders, motorbikes, and 4WD vehicles (accessing for illegal dumping of rubbish).
- Significant weeds occurred throughout the wetlands.
Our Management Approach
The rehabilitation management strategy included the following key components:
- Retention and protection of existing vegetation;
- Intensive management of problematic weed species;
- Revegetation to increase the plant density in degraded areas, and increase the number of potential habitat and foraging species for the endangered Carnaby’s Black Cockatoo (CBC); and
- Promote public ownership and access to the site in a way that also prevents weeds and diseases from being introduced and spreading.
To measure the success of the revegetation plan, strict completion criteria were set, to be achieved within two years of completion of the initial planting program. In summary the:
- Average plant density across all the revegetation areas exceeded targets by more than 50%;
- Carnaby’s Black-Cockatoo foraging and habitat species average density was 50% above requirements; and
- Average weed levels were maintained below the targets for both high priority and other weed species.
The project was successfully completed on schedule and handed over to the City for ongoing management in 2016.
