Airborne lidar has proven a powerful tool for modelling above-ground biomass and carbon, habitat structure and biodiversity of wooded landscapes. Here I describe the application of this technology to the study of two regions in southern Europe: central Spain and Tuscany (Italy). Repeat lidar surveys with a five-year interval, ground-truthed with plot data on tree height and girth, have been used to estimate changes in biomass and carbon and relate these to broad vegetation types. I describe a simulation modelling approach that then uses these estimates to predict landscape-level change under a changing fire regime. In the second application, I investigate the strength of relationship of lidar metrics of vegetation structure with field recording of species diversity of two taxonomic groups: birds and bats. This is a test of the potential of lidar to predict patterns of species diversity over large spatial extents, with relevance to conservation planning and management.
