Targeted weed treatment in three key work areas across cliff sites at Manns Point on Sydney Harbour.  Industrial Ropes Access and Ropes Work Positioning Systems are used by specially qualified WEW staff to undertake these works in areas that cannot be safely accessed on foot.  WEW has planned and delivered weed control in this challenging environment to meet a specific project brief to treat key weeds in high visibility cliff edge and cliff top areas.

Cowan Waters Weed Management

(NSW Office of Environment and Heritage)

Learn More

Six priority sites from Bobbin Head to the Hawkesbury River in the Cowan waters were identified for targeted weed control.  The potential contribution of weed control to the maintenance and enhancement of biodiversity values at the priority sites is considered high.  All sites are surrounded by intact native vegetation and all adjoin the Coastal Saltmarsh endangered ecological community (EEC) listed on Schedule 1 of the NSW Threatened Species Act 1995.  Sites at Apple Tree Bay, Waratah Bay and Jerusalem Bay also contained additional terrestrial EECs.  This contract has been conducted over a period of 4 years.  This has allowed WEW to progressively treat target weeds and identify strategies that are both effective and efficient given the management issues around boat only access and the limited frequency of visits.


Moorebank Biodiversity Offset Planting

(OPEC Systems and the Department of Defence)

Learn More

This project involved implementing extensive revegetation at Moorebank NSW to achieve a biodiversity offset for the Moorebank Unit Relocation Project. WEW was commissioned by OPEC Systems and the Department of Defence to undertake revegetation of over 1 hectare with 40,000 native plants.

The area to be revegetated had previously been used as a grenade range and was, immediately prior to revegetation being progressively cleared of unexploded ordinances (UXOs) by OPEC System’s specialist staff.  Key management issues included the minor areas of tree cover and subsequently lack of shade for young plants in the revegetation area, the potential for predation from hares and wallabies and the potential presence of contaminated material and/or UXOs.  Due to delays early in the project the site did not become available to WEW until early summer.  In order to achieve the required timetable WEW tripled the original work force on the site and was able to plant the required 40,000 plants in just over 3 weeks.  A post planting water regime and summer rains ensured plant survival rates were high.

Cheltenham Girls High School Revegetation

(Department of Education and Training)

WEW was contracted in June 2012 to implement a vegetation management plan at Cheltenham Girls High School (CGHS).  The plan detailed the tasks required as part of development consent conditions to revegetate an area of Sydney Turpentine ironbark Forest (STIF) endangered ecological community (EEC).  The revegetation site contained canopy species consistent with the STIF EEC however little if any native understorey remained.  The vegetation plan has been progressively implemented and will cover a total period of five years.  During the initial two year period ground preparation, planting, watering, plant care, maintenance weeding works, rubbish clearance and track maintenance were undertaken.  A total of 20,581 tubestock were installed in the vegetation management zones at CGHS in years 1 and 2.  Supplementary planting of 100 tubestock was undertaken in year 3 of the project.  Nesting boxes designed for native fauna were constructed and installed by WEW in Year 1 of the project and inspected regularly. Evidence of habitation most likely from bird species have been found in three of the boxes. Crimson Rosellas, Rainbow Lorikeets and King Parrots were observed around and on top of several nesting boxes.
