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 near the rural locality of Silver Spur, approximately 25km northeast of Texas in the Goondiwindi Region of Queensland. It was registered in November 2021 and covers an area of 381.50 hectares.

Environmental planting projects using the FullCAM methodology involve establishing permanent plantings of a mix of native tree species on land previously used for agriculture. To be eligible, the trees must be planted at a sufficient stocking density (typically at least 200 stems per hectare) to achieve a permanent forest cover that can reach at least 2 metres in height and a crown canopy cover of at least 20%.

The Goondiwindi region and the wider Nandewar bioregion have historically been heavily utilized for agricultural purposes, particularly sheep and cattle grazing. The area features a warm, semi-arid to sub-tropical climate characterized by summer-dominated rainfall. Local soils typically consist of fertile self-mulching clays, loams, and scattered basalt deposits.

Also colloquially known as the "Wilga Park" project, this initiative is a $1.96 million collaboration between CO2 AUSTRALIA Pty Ltd and the Queensland Government's Land Restoration Fund. The land was severely degraded by years of intensive sheep grazing prior to the project's commencement. By removing grazing pressure and actively managing pest animals and weeds, the project aims to restore the critically endangered White Box–Yellow Box–Blakely's Red Gum Grassy Woodland. Biodiversity surveys by CO2 Australia ecologists have already confirmed the presence of multiple threatened species on the property, including the squatter pigeon, painted honeyeater, hooded robin, and the spot-tailed quoll. Furthermore, the project is officially certified under the Accounting for Nature® framework, using the Native Vegetation Econd® index to actively monitor its ecological condition and recovery over its 25-year lifespan.
