Yarran Downs Warroo Human Induced Regeneration Project

Yarran Downs Warroo Human Induced Regeneration Project is a Human-Induced Regeneration project located at the 'Yarran Downs' pastoral station in the Warroo locality of Queensland. It is situated in the Balonne local government area, roughly halfway between the rural towns of Surat and St George. It was registered in September 2023 and covers 8,354.93 ha.

Human-Induced Regeneration projects involve establishing permanent native forests through assisted regeneration from in-situ seed sources, including rootstock and lignotubers. The methodology's standard requirements stipulate that land must be managed to allow native vegetation to reach true forest cover, typically meaning at least 20% crown cover and a height of two metres. For this project, activities involve the cessation of mechanical or chemical destruction of regrowth, and managing the timing and extent of livestock grazing.

The surrounding Balonne and Maranoa region is predominantly known for cattle and sheep grazing operations, as well as some dryland and irrigated cropping. The area experiences a semi-arid to subtropical climate, with a highly variable average annual rainfall of around 500-600mm. Soils in the region are generally a mix of sandy loams on low ridges and highly fertile alluvial clay plains (Vertosols) along the floodplains of the Balonne River.

This project is run by Terra Carbon Pty Limited on land that had been previously cleared of vegetation and where regrowth was suppressed for at least 10 years prior to the project commencing. Interestingly, on 7 February 2025, the project area underwent a formal variation where some previously listed land areas were removed from the project boundary.
