Yuin Station, Murchison HIR Aggregation

Yuin Station, Murchison HIR Aggregation is a Human-Induced Regeneration (HIR) project located in the Murchison region of Western Australia, approximately 80 kilometers northeast of the town of Mullewa and roughly 75 kilometers north of Pindar. Registered in September 2020, the project encompasses a massive area of 126,426 hectares within the Shire of Murchison.

The project operates on a pastoral lease historically used for sheep and cattle grazing. The region is characterized as semi-arid rangeland, typically receiving low and variable rainfall averaging between 200mm and 250mm annually. The landscape features open woodlands of Mulga (Acacia aneura) and saltbush flats on soils that are predominantly red earths, shallow loams, and hardpan plains.

This project utilizes the Human-Induced Regeneration methodology, which involves regenerating permanent native forest by managing the factors that previously suppressed regrowth, primarily grazing pressure. Project activities at Yuin Station include managing the timing and extent of grazing (rotational grazing), reducing overall stocking density, and controlling feral animals. Specifically, the station owners have reduced stocking numbers significantly and installed exclusion fencing to manage wild dogs, allowing native vegetation from in-situ seed sources and rootstock to regenerate into forest cover.
