Box-Gum Grassy Woodland for Threatened Species of the Nandewar Bioregion

Box-Gum Grassy Woodland for Threatened Species of the Nandewar Bioregion is an environmental planting project located at Silver Spur, approximately 27km east of Texas in Queensland. It was registered in November 2021 and covers 381.50ha.

Environmental planting projects under the FullCAM methodology involve establishing permanent plantings of mixed native tree species on land previously used for agriculture. To achieve permanent forest cover, these projects generally require planting native trees at a density of at least 200 stems per ha to reach a 20% canopy cover at 2 metres in height.

The Silver Spur and broader Goondiwindi Region is historically known for silver mining and broadacre agriculture, specifically sheep and cattle grazing. The area is considered to have moderate rainfall and soils are generally a mix of traprock, grey loam, and more productive lowland soils.

Also known as the "Wilga Park" project, this initiative is a $1.96 million collaboration with the Queensland Government's Land Restoration Fund. The project was set up to restore heavily degraded grazing land into a natural functioning ecosystem, specifically targeting the critically endangered White Box – Yellow Box – Blakely's Red Gum Grassy Woodland. By diversifying income, the land manager was able to cease sheep grazing to provide vital habitat for threatened native wildlife such as the squatter pigeon, painted honeyeater, and spot-tailed quoll. The biodiversity benefits are tracked using an Accounting for Nature environmental account. In December 2024, the proponent's name was officially varied from CO2 Australia Limited to CO2 AUSTRALIA Pty Ltd.
