Darling River Eco Corridor 3

Darling River Eco Corridor 3 is a Human-Induced Regeneration (HIR) project located on Yathonga Station, approximately 60km southwest of the locality of Louth and 150km southwest of Bourke in western New South Wales. Registered in June 2016, the project covers a significant area of 40,207 hectares within the Mulga Lands and Cobar Peneplain bioregions. The region is historically characterized by rangeland grazing of sheep, cattle, and goats, which has been the primary land use for over a century.

The project operates under the Human-Induced Regeneration (HIR) methodology, which does not involve planting new trees. Instead, it focuses on regenerating permanent native forests from in-situ seed sources, rootstock, and lignotubers by managing "suppressors" that previously stopped vegetation from growing. For this specific project, the primary activities involve managing the timing and extent of livestock grazing and controlling feral animals, particularly goats, which are prevalent in the area. By installing new fencing and water infrastructure, the landholders are able to rotate stock more effectively, allowing native species such as Mulga (Acacia aneura) and Bimble Box to recover.

The environmental conditions in this part of New South Wales are semi-arid to arid, with low and highly variable rainfall averaging around 250mm to 300mm annually. The soils are predominantly red sandy earths and massive red earths, with some clay pans and alluvial soils found closer to the Darling River floodplains. The project is part of a larger aggregation of "Darling River Eco Corridor" projects developed by Terra Carbon (a subsidiary of GreenCollar), which collectively aim to improve drought resilience and biodiversity across the upper catchments of the Darling River.
