The Forest Degradation Experiment is a 5-year project, funded by the European Research Council (ERC), which will generate new methods and datasets to support the mapping and monitoring of changes in aboveground biomass across the world’s tropical forests. The project will collect data on tree/forest structure using a combination of ground-based, i.e. Terrestrial Laser Scanners (TLS), Unoccupied Aerial Vehicle (UAV)-borne Laser Scanners, and traditional forest inventory, with measurements conducted before, and after controlled logging, and again during the recovery. These datasets allow us to measure changes in biomass, normally associated with human disturbances, with minimal error, which can then be used calibrate and validate new methods of mapping change in forest structure and biomass across much larger areas using satellite data. The project is led by Professor Edward Mitchard, with team members including Dr Iain McNicol, Chiara Aquino, and Harry Carstairs.
