Graeme McMahon during the last forty years has worked as a climber in the Dandenong Ranges, east of Melbourne in Australia. In addition, he worked as hand faller in the Central Highlands region felling alpine species for high production logging. A steady diet of large tree removals created a focus on the need for the pursuit of excellence in regard to skill acquisition and problem solving. Despite the mechanization for felling trees in logging operations, Graeme is regularly called upon to conduct hand felling when harvesters are unable to operate and for “skyline” operations. As a mature age student Graeme achieved a Bachelor of Education with majors in Recreation and Biomechanics. This practical experience of removing large trees combined with his academic qual- ifications make Graeme ideal as an expert witness and to present on a range of topics to the tree industry.
