Terraldon Regeneration Project

Terraldon Regeneration Project is a Human-Induced Regeneration project located on Tinnenburra Station, approximately 100km south-west of Cunnamulla in south-west Queensland. It was registered in November 2018 and covers an area of 34,979.81 ha.

Human-Induced Regeneration (HIR) projects involve establishing permanent, even-aged native forests by ceasing activities that previously suppressed tree growth. For this project, permanent native forests are allowed to regenerate from in-situ seed sources, rootstock, and lignotubers. This is achieved by carefully managing the timing and extent of livestock grazing and humanely controlling feral animal populations.

The Cunnamulla region is situated in the Mulga Lands bioregion, which is characterized by a semi-arid climate with highly variable, low rainfall. The soils in this area are typically red earth, cracking clays, and sandy loams. Regional land use is heavily dominated by broadacre pastoral operations, specifically sheep and beef cattle grazing.

Interestingly, the project takes place on a property with a rich Australian pastoral history. In the late 1800s, Tinnenburra Station was owned by the legendary self-made millionaire and pastoral tycoon James Tyson. At the peak of its operation, Tyson built the iconic Tinnenburra Shearing Shed on the property. Boasting 101 blade stands constructed from local timber and corrugated iron, it was widely considered the largest shearing shed in the world at the time.
