Darling River Eco Corridor #35

Darling River Eco Corridor #35 is a Human-Induced Regeneration (HIR) project located in the remote Far West region of New South Wales, approximately 80km northwest of the township of White Cliffs and roughly 200km northeast of Broken Hill. Registered on May 9, 2018, the project encompasses a significant area of 17,851.71 hectares. This project is part of a larger aggregation of properties known as the "Darling River Eco Corridor," managed by Terra Carbon (a subsidiary of GreenCollar), which aims to create a contiguous zone of protected vegetation in the upper catchments of the Darling River system.

The region is characterized by extensive rangeland grazing, primarily for sheep, goats, and cattle. The environment is semi-arid to arid, with low and variable rainfall averaging around 200-250mm annually. The landscape typically features red sandy loam soils and dunefields (Kandosols/Rudosols) supporting Mulga (Acacia aneura) woodlands, while clay-heavy soils (Vertosols) are found in low-lying floodplains and claypans. The project activities focus on regenerating these native woodlands by managing "suppressors", specifically by controlling feral animals (such as goats) and managing livestock grazing pressure to allow young trees to establish and grow into a permanent forest.

Under the Human-Induced Regeneration methodology, the project does not involve planting trees. Instead, it relies on the "assisted regeneration" of in-situ seed sources, rootstock, and lignotubers. By ceasing mechanical clearing and implementing rotational grazing or exclusion fencing, the landholder allows existing vegetation that has been suppressed for at least 10 years to recover. This approach not only sequesters carbon but also helps stabilize fragile soils in the rangelands and improves biodiversity connectivity across the landscape.
