Improving the resilience of threshold regional ecosystems at Nuga Nuga National Park

Origin, in partnership with FBA, has delivered an indirect offset commitment within an area of Nuga Nuga National Park through the Threshold Regional Ecosystem Project (TRE Project). The TRE Project aimed to improve the resilience of threshold Regional Ecosystems (RE) by investing $100,000 in targeted on-ground activities. Origin engaged FBA in early 2022 to scope and design the TRE Project, with delivery completed in 2025.
Located in the southern section of Nuga Nuga National Park in the Arcadia Valley, the TRE Project focused on improving the resilience of threshold RE 11.9.8 âbonewood scrubâ (Macropteranthes leichhardtii) at one of the few remaining locations where relatively intact remnant communities of this RE still exist in Queensland. This unique landscape also supports endangered Brigalow (Acacia harpophylla) and Belah (Casuarina cristata) vegetation communities.
The site is recognised as culturally significant Country for two Traditional Owner groups, who were actively involved in project planning and on-ground delivery alongside FBA, Queensland Parks and Wildlife Service (QPWS) and technical specialists.
This partnership approach was a key strength of the TRE Project. Traditional Owner representatives contributed cultural knowledge and on-ground expertise that helped guide the works while ensuring activities respected cultural values and achieved environmental outcomes.
The TRE Project focused on targeting key environmental pressures impacting the ecosystem, including erosion, uncontrolled water flow and bushfire risk. On-ground works included the construction of a strategic firebreak and erosion control measures across priority areas near Lake Nuga Nuga. Diversion banks and silt trap weirs were installed to slow and redirect water flow, stabilising degraded areas, reducing erosion and improving soil stability to support native vegetation recovery.
The TRE Project demonstrates the value of collaboration in delivering meaningful environmental outcomes. Beyond immediate rehabilitation outcomes, the TRE Project has strengthened stakeholder relationships and identified future opportunities for ongoing restoration within the national park. Origin is proud to support initiatives such as the TRE Project, which combines environmental stewardship, cultural collaboration and practical on-ground action to help protect and restore Queenslandâs natural landscapes for future generations.
