Greenvale Regeneration Project

Greenvale Regeneration Project is a Human-Induced Regeneration (HIR) project located approximately 45km east of Bourke in the semi-arid Orana region of New South Wales. Registered in October 2015, the project covers a significant area of 8,493 hectares on land historically used for grazing. The proponents, Merren and Timothy Turnbull, manage the project on the property, which sits within the Bourke and Brewarrina local government areas.

Human-Induced Regeneration projects involve implementing changes in land management to allow native forests to regenerate. For this specific project, the primary activity involves the humane management of feral animals to reduce grazing pressure on vegetation. By controlling these suppressors, potentially alongside managing livestock grazing, the project aims to establish permanent even-aged native forests from in-situ seed sources (such as rootstock and lignotubers) on land where regrowth had been suppressed for at least 10 years prior to registration.

The region surrounding Bourke is characterized by a semi-arid climate with low and variable rainfall. The landscape typically supports rangeland grazing of sheep, cattle, and goats. The local environment often features red earth (Chromosols) and grey or brown clay soils (Vertosols), which support vegetation communities adapted to dry conditions, such as mulga and bimble box woodlands.
