Western Australia Rangelands Conservation Initiative Site #4.

Western Australia Rangelands Conservation Initiative Site #4 is a Human-Induced Regeneration (HIR) project located in the Gascoyne region of Western Australia, approximately 100 kilometers southeast of Carnarvon. Registered on September 1, 2020, the project encompasses a significant area of 84,014 hectares. The project operates on land historically used for pastoral purposes, where native vegetation regrowth was previously suppressed by agricultural activities.

The project operates under the Human-Induced Regeneration methodology, which involves regenerating permanent even-aged native forests. The core activity for this project is the management of grazing pressure from livestock and feral animals (such as goats) to allow native vegetation to recover. By controlling the timing and extent of grazing, the proponent aims to facilitate the regeneration of in-situ seed sources, including rootstock and lignotubers, eventually achieving forest cover status with a canopy density of at least 20% and a height of 2 meters.

Situated in the Gascoyne region, the project area experiences a semi-arid to arid climate characterized by hot, dry summers and mild winters. Rainfall in this region is generally low and variable, averaging around 200mm to 300mm annually. The landscape typically features red sandy soils, clay pans, and shrublands dominated by Acacia species (such as Mulga), which are well-adapted to the harsh conditions. The region is predominantly used for extensive pastoralism (sheep and cattle grazing), conservation, and mining.

This project is part of a broader portfolio by the proponent, Terra Carbon Pty Limited, titled the "Western Australia Rangelands Conservation Initiative," which includes multiple sites across the rangelands (e.g., Site #8, Site #11). This aggregated approach allows for landscape-scale conservation efforts across vast pastoral leases. As of late 2025, the project has a crediting period extending to 2045.
