Catchment Conservation Alliance - Southern Rivers Initiative Site #2

Catchment Conservation Alliance - Southern Rivers Initiative Site #2 is a Human-Induced Regeneration (HIR) project located in the remote Paroo Shire of South West Queensland. Situated approximately 100km south of Cunnamulla and immediately north of the New South Wales border, the project covers a substantial area of 28,320 hectares. Registered in March 2017, the project operates within the Mulga Lands bioregion, an area historically utilized for extensive sheep and cattle grazing on native vegetation.

The project employs the Human-Induced Regeneration methodology, which differs from environmental planting by focusing on assisting the natural recovery of existing suppressed vegetation rather than planting new seedlings. In this region, regrowth is often suppressed by historic grazing pressure and feral animals. The project activities primarily involve managing the timing and extent of livestock grazing and controlling feral animals, such as goats and pigs, to allow native forests to regenerate from in-situ seed sources, rootstock, and lignotubers.

Environmentally, the region is characterized by a semi-arid climate with low, summer-dominated rainfall, typically averaging between 200mm and 300mm annually. The landscape consists largely of flat to gently undulating plains featuring red earth soils, specifically Kandosols, which are sandy-loams often associated with Mulga (Acacia aneura) vegetation. The project is part of the broader "Southern Rivers Initiative" managed by the proponent Terra Carbon (associated with the GreenCollar Group), which aggregates multiple properties in the catchment to achieve landscape-scale conservation and carbon sequestration outcomes.
