Darling River Eco Corridor #29

Darling River Eco Corridor #29 is a Human-Induced Regeneration (HIR) project located in the Bourke Shire, approximately 70km northwest of the township of Bourke in New South Wales. Registered in November 2017, the project covers a substantial area of 23,762 hectares. The surrounding region lies within the Mulga Lands bioregion, an area traditionally utilized for extensive grazing of sheep, cattle, and rangeland goats.

Human-Induced Regeneration projects generate carbon credits by allowing native forests to regenerate on land where vegetation has been suppressed for at least 10 years. Instead of planting new trees, this methodology relies on assisted regeneration from in-situ seed sources and rootstock. The project activities primarily focus on managing the "suppressors" of regrowth, specifically by installing fencing to control feral animals (particularly goats) and managing the timing and extent of livestock grazing. This reduction in grazing pressure allows native species such as Mulga (Acacia aneura) to re-establish and mature into permanent forest cover.

The local environment is characterized as semi-arid to arid, with low and variable rainfall averaging around 200-250mm annually. The landscape typically consists of red sandy loam soils and dunefields supporting Mulga woodlands, while heavier clay soils (Vertosols) are found in the low-lying floodplains and claypans closer to watercourses. This project is part of a larger aggregation managed by Terra Carbon (a subsidiary of GreenCollar) aimed at creating a contiguous corridor of regenerated vegetation to improve soil stability and biodiversity in the Darling River catchment.
