Delta Regeneration Project

Delta Regeneration Project is a Human-Induced Regeneration (HIR) project located approximately 70km west of Bourke in the Far West region of New South Wales. Registered in April 2015, the project covers a substantial area of 20,409 hectares. The project was originally known as the "Yandaroo Regeneration Project" before being renamed shortly after registration, a change likely linked to the specific "Yandaroo" pastoral station found at these coordinates.

Human-Induced Regeneration projects focus on restoring native forest cover on land where vegetation has been suppressed, typically by agricultural activities like grazing. To meet the methodology's requirements, the project proponents must implement management changes, such as controlling livestock timing and managing feral animals, to allow natural seed sources (like rootstock and lignotubers) to regenerate into permanent, even-aged native forest.

The region surrounding Bourke is a semi-arid landscape characterized by grazing and pastoral leases. The environment features a mix of productive grey soils along floodplains (such as those of the Warrego River system) and soft red soils on the ridges. Vegetation in this area typically includes species such as Mulga, Gidyea, Coolabah, and Beefwood. Nunyara Pty Ltd, the current proponent, notes on their corporate website that they manage projects across the Warriku-Baaka catchment with a focus on landscape rehydration and biodiversity alongside carbon sequestration.

An interesting historical note is the project's rapid evolution; it was renamed from "Yandaroo" to "Delta" less than a month after its initial registration in 2015, coinciding with a variation that removed certain land areas from the project.
