Western Treefarm Project 2B (WTP2B)

Western Treefarm Project 2B (WTP2B) is a plantation forestry project located approximately 45km southwest of Kojonup in the Great Southern region of Western Australia. It was registered in April 2025 and covers 967.20 hectares.

Plantation forestry projects involve establishing a new plantation forest or converting a short-rotation plantation to a long-rotation forest. Standard requirements dictate that the plantation must be managed for commercial harvesting of wood products, adhere to baseline stocking densities, and use approved modelling tools like FullCAM to accurately measure the carbon abatement.

The Kojonup area is well known for mixed farming, including sheep grazing and broadacre cereal cropping, alongside commercial forestry operations. The area is considered to have a Mediterranean climate with moderate to reliable winter rainfall averaging around 530mm annually, and soils are generally lateritic gravels over clay and sandy loams.

This project was set up to sequester carbon by establishing and maintaining a new plantation forest, as well as converting existing short-rotation trees to long-rotation forests across a 25-year permanence period. Additionally, the project proponent, who manages extensive timber and woodchip operations in the area, recently changed its name from Mitsui Bussan Woodchip Oceania Pty Ltd in April 2025 to better reflect its expanding sustainability initiatives. A project variation was also processed in December 2025 that removed some of the originally listed land areas.
