Darling River Eco Corridor 23 (Revoked)

Darling River Eco Corridor 23 (Revoked) is a Human-Induced Regeneration (HIR) project located approximately 45km south-west of Cobar in New South Wales. It was registered in July 2015 and covers 12,375.62 hectares on what was originally known as "The Bluff" pastoral property.

Human-Induced Regeneration projects involve restoring permanent native forests on land where vegetation has been suppressed for at least 10 years prior to the project's commencement. Unlike environmental planting, this method does not involve manually planting trees. Instead, it relies on landholders implementing management changes, such as the cessation of mechanical or chemical destruction of regrowth, and reducing livestock or feral animal grazing pressure, to allow native vegetation to regenerate naturally from in-situ seed sources, rootstock, and lignotubers.

The Cobar region is historically known for the rangeland grazing of sheep and cattle. The area is characterised by a semi-arid climate with variable rainfall averaging around 390mm annually. Soils are generally red earth soils (Kandosols) alongside skeletal soils on the ridges, supporting native vegetation like bimble box (poplar box), mulga, and white cypress pine woodlands.

Managed by Terra Carbon (a subsidiary of GreenCollar), this project was established as part of the wider "Darling River Eco Corridor" aggregation designed to create a contiguous zone of protected habitat across the Western Division of NSW. Originally registered as "The Bluff Human-Induced Regeneration Project", the name was varied in May 2015 to its current title. The project was voluntarily revoked in February 2020 under Section 30 of the CFI Rule, a standard administrative procedure often used to consolidate projects or transition to updated method variations.
