This is a colour photograph of a tree feller using a chainsaw to fell a 150-foot (45-metre) karri tree in Western Australia in 1966. It shows the base of a large karri, with a wedge that is almost half the width of the trunk being reinserted to support the tree.
- This photograph shows a giant karri (Eucalyptus diversicolor) forest in the southern forest region of the southwest of Western Australia. These towering trees grow straight, up to 80 metres high, and achieve a massive girth after 300 to 400 years of growth. Old-growth karri forests typically have an undergrowth of ferns that is lost during logging - southwest WA contains world-renowned areas of significant biodiversity.
- The karri being felled in this photograph is in one of Australia's native forests. In 1788 an estimated 32 per cent of the continent was covered by native forest; today the figure is 21 per cent and continuing to decline as a result of the clearing of forests (including plantations) for agriculture and urban development.
- The man in the photograph is using a chainsaw. Before the advent of the chainsaw, it took two men 3–4 hours to fell a karri the size of the one in this photograph, using axes and a push-pull saw.
- Native forests were logged before the damaging effects of unrestrained logging were understood in the community. Today only small sections of original old-growth karri forest remain in national parks and other protected areas; some karri is still logged in regrowth areas and plantations for project and craft uses.
- Timber is felled for use in a variety of timber products. Karri timber is valued for furniture and flooring because of its grain and straightness, and for structural applications because of its great strength.
