Fluorescence Lidar Monitoring of Vegetation Status

Remote laser-induced fluorescence monitoring can complement passive reflectance measurements on vegetation. Vegetation classification and status assessment is normally performed by air- or spaceborne multi-spectral scanners. An increased research activity in the field of vegetation monitoring is motivated by the abundant stressed forests of Europe. We have used a mobile lidar system for remote studies of laser-induced fluorescence in vegetation. Point monitoring of fluorescence spectra is performed, but also multi-spectral imaging using a newly designed measurement system. Swedish experience in several field tests being part of the European LASFLEUR project is reported. Collaboration with expertise in plant physiology is stressed.
