Developing a dual-wavelength full-waveform terrestrial laser scanner to characterize forest canopy structure
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.

Destructive sampling of oak LAI at Alice Holt
A team from the Universities of Salford, UCL and Newcastle and Forest Research UK completed the destructive sampling of three 80 year old oak trees at Alice Holt in Surrey.
Following leaf off scanning in March and leaf-on scanning in June the three oaks were felled and all leaves removed by the team and bagged to determine their dry weight. We will estimate tree LAI through measurements of specific leaf area (SLA) on a sample of 800 leaves. More results to follow...but here's a short video to illustrate the approach...on YouTube
