Accurate, high-resolution mapping of aboveground carbon density (ACD, Mg C ha-1) could provide insight into human and environmental controls over ecosystem state functioning, support conservation climate policy development. However, ACD has proven challenging, particularly in spatially complex regions harboring a mosaic land use activities, or remote montane areas that are difficult to access poorly understood ecologically. Using combination field measurements, airborne Light Detection Ranging (LiDAR) satellite data, we present the first large-scale, estimates stocks Madagascar.We found elevation fraction photosynthetic vegetation (PV) cover, analyzed throughout forests widely varying structure condition, account for 27-67% spatial variation ACD. This finding facilitated extrapolation LiDAR-based total 2,372,680 ha using data. Remote, humid sub-montane harbored highest densities, while was suppressed dry spiny ecosystems, as well most lowland with heightened activity. Independent activity, were subject strong physiographic expressed through tropical forest canopy measured LiDAR.High-resolution is possible regions, without thus monitoring can be brought highly endangered Malagasy climate-change mitigation biological strategy.
