Darling River Eco Corridor 4

Darling River Eco Corridor 4 is a Human-Induced Regeneration (HIR) project located in the Cobar Shire Council area of Western New South Wales. The project area covers approximately 61,878 hectares and is situated roughly 90km southwest of the major service centre of Cobar. The region is characterized by vast pastoral leases used primarily for grazing sheep, cattle, and goats.

Registered in April 2016, this project operates under the Human-Induced Regeneration methodology. This method requires landholders to cease activities that previously suppressed vegetation growth, primarily unrestricted grazing by livestock and feral animals. By managing the timing and extent of grazing and installing infrastructure such as fencing and water points, the project allows native forest cover to regenerate from in-situ seed sources (rootstock and lignotubers). The goal is to restore permanent even-aged native forests, which sequester carbon and improve soil stability.

The project sits within the Mulga Lands bioregion, a semi-arid environment with variable rainfall averaging between 250mm and 350mm annually. The terrain typically consists of flat to undulating red sandy earth and loam soils, often hosting species such as Mulga (Acacia aneura), Turpentine (Eremophila sturtii), and Budda (Eremophila mitchellii).

An interesting facet of this project is its inclusion in the broader "Darling River Eco Corridor" initiative managed by Terra Carbon (a subsidiary of GreenCollar). This initiative aggregates multiple properties across the Darling River catchment to create a large-scale conservation corridor. These projects are designed to provide drought resilience and diversified income for graziers, allowing them to invest in new farm infrastructure while restoring the landscape.
