Darling River Eco Corridor 27

Darling River Eco Corridor 27 is a Human-Induced Regeneration (HIR) project located in the rangelands of Western New South Wales, approximately 95km west of the township of Bourke and 60km northwest of Louth. Registered in February 2018, the project encompasses a significant land area of 37,569 hectares within the Mulga Lands bioregion. The surrounding region is characterized by extensive pastoral leases, primarily used for grazing sheep, cattle, and goats on native vegetation.

The project operates under the Human-Induced Regeneration methodology, which differs from tree planting projects. Instead of planting seedlings, the project proponents manage the land to allow existing native seed banks and rootstock to regenerate naturally. This is achieved primarily by controlling the timing and extent of livestock grazing and actively managing feral animal populations (such as goats) that historically suppressed vegetation growth.

Environmentally, the site is situated in a semi-arid climate zone with a highly variable annual rainfall averaging between 300mm and 400mm. The landscape features slightly undulating plains with soils dominated by red sandy loams (red earths), which transition to grey clays in areas closer to watercourses. The vegetation naturally regenerating on the property includes species such as Poplar Box (Eucalyptus populnea), Mulga (Acacia aneura), and various shrub species like Hop Bush (Dodonaea viscosa) and Turpentine (Eremophila sturtii).

A notable aspect of this project is its inclusion in the broader "Darling River Eco Corridor" initiative managed by GreenCollar (via its subsidiary Terra Carbon). This landscape-scale aggregation aims to create contiguous zones of protected vegetation along the Darling River catchment. Corporate reporting indicates that Australian Carbon Credit Units (ACCUs) from this specific project have been surrendered by major entities, such as Woodside Energy, to offset their greenhouse gas emissions.
