Working within the Gardens of Stone National Park, we implemented our weed control services to protect native habitats and threatened species. After our treatment of invasive species, the project has transitioned into a careful maintenance phase to support long-term ecosystem health.

Project Details:

Method & Technique:

• Bush Regeneration
• Targeted Weeding

Project Outcomes:

Our team successfully completed the primary weed control program targeting Blackberry (Rubus fruticosus agg.) at Gardens of Stone National Park, an area recognised for its significant birdlife and threatened species habitat. In addition, invasive Monterey Pine (Pinus radiata) was treated using the ringbarking method to prevent further encroachment into native vegetation The work was carried out by our experienced and AQF3 SMARTtrain Chemical Accreditation certified personnel, using appropriate herbicide application methods to ensure effective treatment while taking extra care to minimise impacts on native flora and fauna. We have now entered the maintenance phase, with ongoing, carefully managed follow-up treatments to support the long-term protection of this sensitive ecosystem.

Over multiple years, we restored key wetland habitats within the Sydney Airport precinct, balancing ecological rehabilitation with aviation safety requirements. Through our weed management services, we transform degraded areas into strong ecosystems.

Method & Technique:

• Bush Regeneration
• Broadscale Herbicide Spraying
• Aquatic Weed Control
• Planting
• Ecological Restoration
• Aquatic Weed Treatment
• Habitat Management

Project Outcomes:

We successfully completed a multi-year bush and wetland regeneration project for our client, Sydney Airport, spanning from 2019 to 2022. The project began with a focus on intensive primary works to control dense infestations of invasive species such as Cestrum parqui (Green Cestrum), Lantana camara, Chrysanthemoides monilifera subsp. rotundata (Bitou Bush), Ludwigia peruviana (Water Primrose), and various exotic climbers. These weeds were treated in staged sections to support effective restoration and site recovery.

Sydney Airport’s vision was to rehabilitate the riparian habitat around two wetland ponds, creating a functional and resilient natural area while minimising the risk of attracting large bird populations near the airport. Our team worked to achieve this balance by restoring native vegetation and managing habitat complexity appropriately.

From 2020 to 2022, we carried out regular maintenance works to consolidate earlier progress. Weed densities were effectively maintained or reduced across most work zones, with major improvements noted in Engine Pond West, Engine Pond East , and Mill Stream . Native vegetation showed strong regeneration, supported by our follow-up work and favorable seasonal rainfall.

In 2022, the final year of the contract, our efforts shifted to controlling vine and herbaceous weeds such as Rumex sagittatus and Anredera cordifolia, particularly in areas with good native cover or previous plantings. We also carried out supplementary planting to increase biodiversity, enhance habitat corridors, and reduce future weed re-establishment in cleared zones.

Throughout the project, a diverse range of native fauna were observed, including Striped Marsh Frogs, Eastern Water Skinks, Blue-tongued Skinks, Black Swans, Pelicans, Honeyeaters, Swamp Hens, and Superb Fairy-wrens — highlighting the ecological value of this urban stepping stone habitat.

This project was completed to a high standard, with all objectives met through careful planning, consistent follow-up, and strong teamwork. It stands as a successful example of large-scale ecological restoration in a complex urban setting.

Our project at the Upper Ponds Creek spans over nine different sites, we utilised many of our services to enhance both the environmental health and community resources along the Upper Ponds Creek entrance. We are proud to continue to work on projects where we can tailor ecological solutions to diverse landscapes.

Method & Technic:

• Aquatic Weed Treatment
• Broadscale Herbicide Spraying
• Bush Regeneration
• Revegetation
• Track Maintenance

Project Outcomes:

The Upper Ponds Creek project showcased our team’s ability to apply a broad range of ecological techniques and knowledge to deliver successful outcomes across nine diverse sites. This large-scale restoration effort required a tailored approach at each location, with focused strategies including track maintenance, edge weed control, resilient area management, and the preservation of regenerating zones—particularly through the protection of native shrubs and trees from invasive vines. Our work also enhanced the visual amenity of the area, with diligent weed control improving the outlook for visitors at key vantage points. We successfully maintained previously revegetated areas, executed primary and targeted weeding, and carried out routine maintenance to ensure long-term resilience. The effective management of the Hazard Reduction Zone (HRZ) further supported site safety and ecological balance. By combining expertise, industry-standard practices, and a commitment to ecological integrity, we’ve not only achieved the project’s objectives but also contributed to the lasting health and appeal of the Upper Ponds Creek landscape.

Our team’s experience in enhancing reserves like the Field of Mars Reserve, where we were able to execute focused maintenance during wet weather conditions shows our dedication to enhancing ecosystems despite challenges.

Method & Technique:

• Bush Regeneration
• Track Maintenance

Project Outcomes:

Our team has made strong progress in preserving and enhancing the Field of Mars Reserve throughout the 2022–2024 contract period. Despite challenges such as persistent rain—particularly in spring and summer(2023-2024)—that fueled rapid weed growth, we remained focused on intensive maintenance across key areas including creeklines, drainage lines, resilient bushland, and walking tracks. With the conditions favouring the spread of herbaceous, vine, and grass weeds, we prioritised responsive maintenance over primary works, tailoring our strategies to the unique needs of each zone across Field of Mars North, South, and Entrance. This flexible, targeted approach has helped control invasive species, supported native regeneration, and safeguarded the ecological integrity of the reserve. As we look ahead, our team remains committed to adapting and refining our efforts to ensure the long-term health and vibrancy of this vital natural space for both wildlife and the community.

Project Outcomes:

Towra Point Nature Reserve is located on the Kurnell Peninsula and forms part of the southern shore ofBotany Bay. This Nature Reserve encompasses important vegetation communities, including Swamp Oak Floodplain Forest, Kurnell Dune Forest, Littoral Rainforestand Coastal Saltmarsh. Three of the six sites (Sites1, 2 & 3) contain the endangered (NSW)Syzygium paniculatum-Magenta Lilly Pilly.

Works were aimed at promoting the wellbeing of and assisting the repopulation of the endangered Syzygium paniculatum through all sites, as well as the Endangered Ecological Communities of the Nature Reserve. This was achieved through the targeted control of invasive weeds such as Ground Asparagus, Lantana, African Olives and Bitou Bush through the various methods discussed in this report. Worked areas have seen significant improvement with the overall reduction in weed densities and regeneration of native species. Spot spraying was also carried out under very sensitive conditions and completed successfully by our well-trained, experienced team.

In the sand dune area, we conducted targeted weeding and installed 2,000 native saltmarsh plants following the treatment of Juncus acutus.

Project Outcomes:

As part of Hornsby Shire Council’s long-term vision for conservation, our team has been actively working in the bushland since 2020. We manage six designated zones, where we are successfully controlling weed species and supporting the natural regeneration of the area.

Over the past four years, we have carried out post-burn weed control, track maintenance, and planting within the contracted zones—and our efforts are ongoing as we continue to support the ecological health of the area.
