South Australian Conservation Alliance - Site #2

South Australian Conservation Alliance - Site #2 is a Human-Induced Regeneration (HIR) project located in the Gawler Ranges bioregion, approximately 90km north of the township of Wudinna in South Australia. Registered in February 2020, the project encompasses a massive 77,354 hectares of pastoral land. The area is situated at a unique ecological intersection, bordering the rocky Gawler Ranges, the arid lands to the north, and the mallee country to the south.

The Human-Induced Regeneration methodology focuses on regenerating native forests by addressing the "suppressors" that previously prevented growth. Unlike environmental planting, this method relies on the germination of in-situ seed sources and rootstock. For this specific project, the primary activities involve managing the timing and extent of livestock grazing and controlling feral animals, particularly goats, which are known to decimate young vegetation. These changes allow the land to naturally regenerate towards a forest cover status.

The region creates a challenging semi-arid environment characterized by low rainfall and complex soil structures ranging from rocky outcrops to sandy dunes. The regenerating vegetation is dominated by resilient species such as Dodonaea viscosa (Sticky Hopbush), Senna artemisioides, Casuarina pauper (Black Oak), and Alectryon oleifolius (Bullock Bush).

An interesting feature of this project is its commitment to a 100-year permanence period, ensuring the stored carbon remains sequestered for a century. It operates under the broader "South Australian Conservation Alliance" portfolio managed by Terra Carbon, often in partnership with GreenCollar. The project has demonstrated high monitoring accuracy, with reported biomass classification accuracy exceeding 87%, well above the required regulatory minimums.
