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 1,560.32ha.

Environmental planting projects involve planting native trees and shrubs to establish a permanent forest cover. They typically require meeting standard stocking densities, such as the 292 stems per hectare achieved in certain planting blocks of this project, to ensure successful long-term canopy cover and verified carbon sequestration.

The surrounding Mid West Wheatbelt region is heavily cleared and is 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. Project site soils are highly diverse, featuring a mixture of yellow sands, red loam, and calcareous rubbly sands over calcrete.

This project establishes permanent plantings of mixed native tree species on land that was predominantly used for agriculture for at least five years prior to commencement. It is a key addition to Carbon Neutral Pty Ltd's wider Yarra Yarra Biodiversity Corridor, reintroducing over 70 local endemic species (such as York and Salmon gum) to restore degraded farmland and create vital wildlife habitat bordering the Greenough River. A notable update to the project occurred in November 2225, when a variation was recorded to remove specific areas from the registered boundary.
