Forest stands are generally in a status from the severely disturbed (almost no live woody biomass), or the partially damaged, to different stages of recovery and to maturity. To estimate realistic changes of carbon stock and fluxes of a disturbed forest stand, both pre-disturbance ecosystem status and the extent and severity of disturbance need to be known. Here we show a prototype work to achieve this by integrating small foot-print Lidar data, forest disturbance derived from Landsat Vegetation Change Tracker (VCT), and an individual-based structure height Ecosystem Demography (ED) model. Our study area is Charles County, Maryland, due to its natural disturbances and less land use change following the disturbances. Lidar provides critical information on forest canopy height, improving the accuracy of forest biomass estimates prior to disturbance; Long-term Landsat data provide valuable information on wall-to-wall disturbance extent and severity; ED model plays a central role by linking both Lidar canopy height and Landsat disturbances with ecosystem processes. Our integration system could provide more realistic wall-to-wall carbon stock and fluxes change for dynamic forest ecosystems.
