Vegetation structure is important for measuring forest growth and the carbon cycle. Developed by the University of Salford and Halo Photonics Ltd, the Salford Advanced Laser Canopy Analyser (SALCA) is a unique multi-spectral, full waveform laser scanner using two wavelengths allowing distinction between leaves and woody material. This blog follows our research funded by the UK NERC and involving University of Newcastle, University College London and UK Forest Research.
Mark Danson was in Cambridgeshire last week helping out with a Newcastle University and Centre for Ecology and Hydrology (CEH) project to assess the 3D structure of hedgerows for biodiversity management. Dr Rachel Gaulton and PhD researcher Lyndsey Graham are working with Drs France Gerard and Jo Staley from CEH, Wallingford, UK. The test site on Wimpole Estate is a 200 m section of hedgerow that has undergone a range of management treatments. SALCA was used to measure 18 different stretches of hedgerow, along with Newcastle's Leica scanner. Lyndsey and the team measured a wide range of ecological parameters and will now assess the laser scanner data for characterising hedgerow structure.
