Darling River Eco Corridor 20 (Revoked)

Darling River Eco Corridor 20 (Revoked) was a Human-Induced Regeneration (HIR) project located on the Nullogoola Station property, approximately 50km west of Cobar in New South Wales. Registered in July 2015 and covering a substantial area of 15,924 hectares, the project was part of a broader initiative by the proponent, Terra Carbon Pty Limited (a subsidiary of GreenCollar), to establish an ecological corridor along the Darling River catchment.

Human-Induced Regeneration projects focus on restoring native forests by changing land management practices to allow vegetation to recover. Unlike tree planting, this methodology relies on natural regeneration from in-situ seed sources (like rootstock and lignotubers). For this specific project, the primary activities involved managing the timing and extent of livestock grazing and controlling feral animals to reduce suppression on regrowing trees.

The Cobar region is characterized by a semi-arid climate with an average annual rainfall of approximately 390mm. The landscape typically features red earth and clay loam soils, supporting mulga and bimble box woodlands, which are heavily utilized for sheep and goat grazing. This project was originally named the "Nullogoola Human-Induced Regeneration Project" before being renamed in May 2015. It was voluntarily revoked in December 2017 under Section 30 of the CFI Rule. The revocation was likely part of an administrative consolidation, as numerous projects in the "Darling River Eco Corridor" series (including numbers 10 through 24) were revoked around the same period, potentially to be re-registered or aggregated into larger carbon estimation areas.
