Yarran Downs Warroo Human Induced Regeneration Project

Yarran Downs Warroo Human Induced Regeneration Project is a Human-Induced Regeneration project located near the locality of Warroo in the Balonne Shire of Queensland, approximately 52km north of St George and 74km south of Surat. It was registered in September 2023 and covers an area of 8,354.93ha. In February 2025, a variation was made to the project, removing some specific areas from the original project boundary.

Human-Induced Regeneration (HIR) projects involve establishing permanent, even-aged native forests through assisted regeneration from in-situ seed sources like rootstock and lignotubers. A standard requirement of this methodology is that the land must have been cleared of vegetation and regrowth suppressed for at least 10 years prior to the project starting. For this project, regeneration is achieved by ceasing mechanical and chemical suppression of regrowth and actively managing the timing and extent of livestock grazing.

The Balonne Shire region is well known for agriculture, predominantly the grazing of sheep and cattle on native vegetation, as well as some cotton and wheat cropping. The region generally has a semi-arid climate with moderate, highly variable rainfall averaging around 500mm to 600mm annually. The soils in the Maranoa-Balonne area are generally a mix of Chromosols (texture-contrast soils), Kandosols (red, yellow and grey massive earths), and Vertosols (cracking clays) which are highly prized for agricultural production.

Terra Carbon Pty Limited acts as the proponent for the project, working alongside the landowners to help restore degraded native vegetation ecosystems while successfully generating Australian Carbon Credit Units (ACCUs).
