Darling River Eco Corridor 20 (Revoked)

Darling River Eco Corridor 20 (Revoked) is a Human-Induced Regeneration (HIR) project located on Nullogoola Station, approximately 45km west of the major township of Cobar in western New South Wales. The project was registered in July 2015 and covered a significant area of 15,924 hectares within the Cobar Peneplain bioregion. This region is predominantly utilized for grazing, specifically sheep and goats, with the local landscape characterized by mulga communities and bimble (poplar) box woodlands.

The project operated under the Human-Induced Regeneration methodology, which awards carbon credits to landholders who allow native forests to regenerate by removing suppression activities. Standard requirements for this method typically involve managing the timing and extent of livestock grazing, installing fencing, and controlling feral animals to ensure vegetation can recover to forest status. In this specific instance, the project focused on managing grazing pressure and humane feral animal control to facilitate regrowth from in-situ seed sources like rootstock and lignotubers.

Environmentally, the Cobar region is classified as semi-arid with a median annual rainfall of approximately 390mm, though this is highly variable. The soils in the project area are typical of the Cobar Peneplain, consisting largely of red earths and lithosols (loams and clays) which support the native shrublands and woodlands. The landscape is prone to erosion, and the station owners have historically implemented specific innovation projects to control gully erosion along tracks and fencelines to improve land productivity.

The project was voluntarily revoked in December 2017 under Section 30 of the CFI Rule, meaning it no longer generates carbon credits, although the property owners have remained active in sustainable land management. The proponent, Terra Carbon Pty Limited, is a subsidiary of the environmental markets developer GreenCollar. The station owners, Dave and Rikki Allen, are well-regarded in the region for their proactive approach to land management, including hosting Landcare education days for local students and participating in wild dog control initiatives.
