Yimba Biodiversity Project

Yimba Biodiversity Project is a permanent mixed-species environmental planting project located in Wandana within the Shire of Chapman Valley, approximately 90km northeast of Geraldton in Western Australia. It was registered in June 2022 and originally covered 1,560.32ha, though a variation in November 2025 removed some areas from the project boundary.

Environmental planting projects involve planting native trees and shrubs to establish a permanent forest cover. Under the FullCAM methodology, these projects must meet standard stocking densities to ensure successful long-term canopy cover and verified carbon sequestration, with certain planting blocks of this project recorded as achieving 292 stems per hectare.

The surrounding Mid West Wheatbelt region is characterised by broad agricultural land, predominantly used for cropping, such as wheat and canola, and grazing. The inland Chapman Valley area experiences a semi-arid to medium rainfall climate, averaging around 315mm to 400mm annually. Soils in the region are diverse, typically featuring red loam, sandy loam, and clay.

The project is a recent addition to Carbon Neutral Pty Ltd’s portfolio within the Yarra Yarra Biodiversity Corridor, a region where over 90% of the native York and Salmon gum woodlands have been cleared for agriculture since the early 1900s. By establishing permanent plantings of local native species on degraded agricultural land, the project aims to generate 54,000 ACCUs over its lifetime. It is protected under a 100-year carbon right and aligns with multiple UN Sustainable Development Goals, including Climate Action, Clean Water and Sanitation, and Life on Land.
