Western Treefarm Project 2B (WTP2B)

Western Treefarm Project 2B (WTP2B) is a plantation forestry project located in the locality of Tonebridge, approximately 60km southeast of Boyup Brook and 55km west of Kojonup in the Great Southern region of Western Australia. Registered on April 28, 2025, the project covers a total area of 967.20 hectares. The project is situated in a region heavily utilized for mixed farming, specifically sheep and cattle grazing, as well as commercial timber plantations (typically Tasmanian Blue Gum or Radiata Pine).

The project operates under the Carbon Credits (Carbon Farming Initiative, Plantation Forestry) Methodology Determination 2022. This methodology credits carbon abatement through two distinct activities: establishing new plantation forests on land that has been clear of forest for at least five years, and converting existing short-rotation plantations (grown for woodchips/pulp) into long-rotation plantations (grown for sawlogs/structural timber). By extending the rotation period, the trees are allowed to grow larger and store carbon for a longer duration before harvest.

Environmental conditions in the Boyup Brook and Tonebridge area are characterized by a Mediterranean climate with cool, wet winters and dry, warm summers. The region falls within a high rainfall zone, typically receiving between 600mm and 800mm annually, which is ideal for forestry operations. The soils in this southern portion of the shire are predominantly gravelly loams, yellow soils, and leached sands, often overlying clay subsoils.

The project proponent, Mitsui & Co. Wood Resources Oceania Pty Ltd (MWRO), is a major player in the Australian forestry sector, managing significant assets for woodchip export and sustainable timber. Notably, on December 19, 2025, a variation was made to the project to remove certain areas from the registered boundary, likely due to operational adjustments or land suitability assessments.
