Darling River Eco Corridor 23 (Revoked)

Darling River Eco Corridor 23 (Revoked) was a carbon sequestration project located on "The Bluff" station, approximately 40 to 50 kilometers south of Cobar, New South Wales. Originally registered in July 2015 as "The Bluff Human-Induced Regeneration Project," it was renamed in May 2015 to align with the proponent's broader "Darling River Eco Corridor" conservation initiative. The project covered a substantial area of 12,375 hectares before being voluntarily revoked in February 2020.

The project operated under the Human-Induced Regeneration (HIR) methodology. This method credits landholders for regenerating native forests by ceasing suppression activities, such as mechanical clearing or uncontrolled grazing, to allow vegetation to recover. In this region, typical regeneration activities involve managing the timing and extent of grazing (often by goats or sheep) and controlling feral animals to protect emerging rootstock and lignotubers.

The Cobar region is characterized by a semi-arid climate with an average annual rainfall of approximately 320mm. The landscape at "The Bluff" features undulating country with red loam to sandy loam soils, transitioning to stony ranges in the southern areas. The vegetation is dominated by native species such as Mulga (Acacia aneura), Bimble Box (Eucalyptus populnea), and Cypress Pine (Callitris glaucophylla). The property has historically been used for grazing Santa Gertrudis cattle and Merino sheep, as well as harvesting rangeland goats.

The project was managed by Terra Carbon Pty Limited, a subsidiary of the GreenCollar Group. It was part of a larger suite of projects known as the Darling River Conservation Initiative, which aimed to create biodiversity corridors across the upper catchments of the Darling River. Although this specific project instance was revoked, the broader initiative continues to operate numerous active carbon projects in the Cobar Peneplain and Western NSW rangelands.
