Yimba Biodiversity Project

Yimba Biodiversity Project is an 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 1560.32ha.

Environmental planting projects under the Carbon Credits Methodology involve planting a mix of native trees and shrubs to establish a permanent forest cover. They require meeting standard stocking densities, typically a minimum of 200 stems per hectare, to ensure successful long-term canopy cover and verified carbon sequestration, with this project achieving an excellent 292 stems per hectare in certain planting blocks.

The surrounding Mid West Wheatbelt region is heavily cleared and traditionally known for its extensive agricultural operations, primarily broadacre cropping and sheep grazing. The region experiences a semi-arid, Mediterranean climate with low-to-medium rainfall. The site's soils are highly diverse, featuring a mixture of yellow sands, red loam, and calcareous rubbly sands over calcrete.

This project establishes permanent plantings of native tree species on land that was predominantly used for agricultural purposes for at least five years prior. It is a key addition to Carbon Neutral Pty Ltd's wider Yarra Yarra Biodiversity Corridor, reintroducing over 70 local endemic species like York and Salmon gum to restore degraded farmland and create vital wildlife habitat bordering the Greenough River. In November 2025, a variation to the project area was recorded, removing specific areas from the registered boundary.
