Darling River Eco Corridor #26

Darling River Eco Corridor #26 is a Human-Induced Regeneration (HIR) project located approximately 110 kilometers west of Bourke in the remote Far West region of New South Wales. Registered on January 17, 2017, the project covers a substantial area of 24,209 hectares within the Mulga Lands bioregion. This area is traditionally utilized for extensive grazing of sheep, goats, and cattle, operating within the state's Western Division.

Human-Induced Regeneration projects focus on restoring native forests through the management of factors that suppress regrowth, rather than through direct planting. In this specific project, the proponent, Terra Carbon Pty Limited (a subsidiary of GreenCollar), works with landholders to cease mechanical clearing and control grazing pressure. By managing the timing and extent of livestock grazing and humanely controlling feral animals, particularly goats, which are prevalent in the area, the project allows existing rootstock and lignotubers to regenerate into a permanent even-aged native forest.

The environment of this region is classified as semi-arid to arid, typically receiving less than 350mm of rainfall annually, which makes active planting difficult and natural regeneration a more viable method for carbon sequestration. The landscape consists of slightly undulating red sandy loam soils, characteristic of the "red country" found west of the Darling River. Vegetation surveys on the property have identified dominant species such as Turpentine (Eremophila sturtii), Silver Cassia (Senna artemisioides), and Hopbush (Dodonaea viscosa), alongside canopy trees like Mulga and Beefwood.

This project is part of a broader aggregation of "Darling River Eco Corridor" initiatives designed to create a landscape-scale environmental benefit while diversifying income for local graziers. By integrating carbon farming with traditional agriculture, the project aims to improve soil stability and reverse land degradation caused by historical overgrazing. The project has successfully generated Australian Carbon Credit Units (ACCUs) by proving that the native vegetation has transitioned from suppressed regrowth to forest cover over time.
