Darling River Eco Corridor 18 (Revoked)

Darling River Eco Corridor 18 (Revoked) was a Human-Induced Regeneration (HIR) project located at "Mulchara Park" station, approximately 110km southwest of the major outback town of Cobar in New South Wales. Registered in July 2015, the project covered a significant area of 14,686 hectares within the semi-arid rangelands of Western NSW. The region is historically dominated by grazing operations, particularly for sheep and rangeland goats, and is characterized by flat red loamy soils, sandy creek beds, and vegetation types such as Mulga, Rosewood, and Bimble Box.

The project operated under the Human-Induced Regeneration methodology, which awards carbon credits for regenerating native forests on land where vegetation has been suppressed for at least 10 years. Instead of planting new trees, this method relies on assisted regeneration from in-situ seed sources (like rootstock and lignotubers). Project activities focused on managing the timing and extent of grazing pressure from livestock and humanely controlling feral animals to allow the native forest to recover.

In January 2020, the project was revoked under Section 30 of the Carbon Credits (Carbon Farming Initiative) Rule 2015. This section governs voluntary revocation, indicating the proponent (Terra Carbon Pty Limited, a subsidiary of GreenCollar) chose to cancel the project registration, rather than it being forcibly revoked for non-compliance. Voluntary revocation often occurs when proponents wish to re-configure project boundaries, transition to a newer methodology, or alter their commercial strategy. "Darling River Eco Corridor" refers to a wider aggregation of carbon projects managed by GreenCollar across the Darling River catchment.
