2025 Twin Pines mallee reforestation

2025 Twin Pines mallee reforestation is a Reforestation by Environmental or Mallee Plantings project located in the Shire of Mount Marshall, situated in the northeastern Wheatbelt of Western Australia. Registered in August 2025, the project covers approximately 50 hectares and is positioned roughly 60 kilometers north of the town of Koorda and northeast of Dalwallinu.

The project utilizes the 2024 Reforestation by Environmental or Mallee Plantings-FullCAM methodology, which involves establishing permanent native vegetation on land that was previously cleared for agricultural use. Specifically, this project focuses on planting a mix of native tree and shrub species, likely dominated by "mallee" eucalypts, multi-stemmed trees adapted to the semi-arid conditions of the region. The methodology requires maintaining these plantings to sequester carbon, modeled using the Full Carbon Accounting Model (FullCAM).

The surrounding Mount Marshall region is characterized by a semi-arid climate with low winter-dominant rainfall, typically averaging between 280mm to 325mm annually. The landscape supports broadacre cereal cropping (wheat and barley) and sheep grazing, though it lies near the margins of the viable grain belt where salinity and soil fragility are common management issues. The soils in this location are generally ancient, weathered granitic soils, often consisting of sandy loams or ironstone gravels over clay subsoils. The "Twin Pines" project name and the specific focus on mallee reforestation suggest an effort to restore unproductive or marginal farmland to its original native vegetation state, providing biodiversity benefits alongside carbon sequestration.
