LIDAR finds a giant in southern Tasmanian forest

April 2007

Management of giant trees is an important issue for Forestry Tasmania.  Currently all trees greater than 85m high and 280 cubic metres are given special management zones.  The trees are maintained on a register by the Giant Trees Committee who also coordinate the naming of giant trees. LIDAR (light detection and ranging) technology is being explored by FT and CRCF project 1.1 (Monitoring and measuring for growth and health) and has potential uses in biodiversity management. LIDAR uses a laser beam to build a profile of the forest canopy.  Tree height information allows the detection of candidate giant trees, the size of which can then be verified from the ground.  Forestry Tasmania staff recently found two previously unrecognised giant trees in southern Tasmania that are now fully protected from harvesting .  For the full story, go to http://www.gianttrees.com.au/laser_technology.html
