ACTDEP037: Select and justify choices of materials, components, tools, equipment and techniques to effectively and safely make designed solutions.

Aboriginal Cultural Standards Framework: Cultural Responsiveness Standard - Staff embed Aboriginal cultural knowledge, such as traditional timber use in the Kimberley and Pilbara regions, to demonstrate respect for community values and environmental stewardship.

Cross-Curriculum Priority: Aboriginal and Torres Strait Islander Histories and Cultures - Students explore pre-contact and contemporary uses of Australian timbers to understand Indigenous innovation and adaptation in material use.

Reading: Sustainable Timber Sourcing and Environmental Impact

Sustainable timber sourcing is crucial to minimize environmental impact in woodwork. It involves harvesting wood without depleting forests, ensuring regeneration. In Western Australia, practices protect unique timbers from the Kimberley and Pilbara. Boab and bloodwood in the Kimberley are sourced responsibly to avoid deforestation. In the Pilbara, mulga and gidgee are harvested with care to preserve arid ecosystems. Unsustainable logging leads to soil erosion, loss of biodiversity, and climate change.

Certification schemes like FSC ensure ethical sourcing. Indigenous knowledge from Kimberley and Pilbara communities guides sustainable methods. Replanting and selective cutting maintain balance. Environmental impact includes carbon sequestration, as trees absorb CO2. WA jarrah forests store carbon, but overharvesting releases it. In woodwork, using recycled or certified timber reduces footprint. Future generations benefit from preserved regions like Kimberley. Sustainable practices support biodiversity and economy.
