Vegetation structure from laser scanning

Detailed knowledge of the structure of overstorey and understorey vegetation around us has many applications, from nature conservation to forest management and fire risk reduction. Current measurement methods are slow and labour intensive.
Together with CSIRO and the Terrestrial Ecosystem Research Network, we have been developing automated technologies to map vegetation structure from LiDAR – laser scanning data derived from handheld scanners or airborne measurements.
These data have a wide range of applications. They help ecologists understand habitat quality and its suitability for different species. They also help fire managers to assess fire risk and plan hazard reduction burns. The data can also be used to measure biomass and carbon storage in forests.
