Above ground biomass and tree species richness estimation with airborne lidar in tropical Ghana forests

Gaia Vaglio Laurin, Nicola Puletti, Qi Chen, Piermaria Corona, Dario Papale, Riccardo Valentini
2016 International Journal of Applied Earth Observation and Geoinformation  
This research aims at estimating aboveground biomass and tree species richness using discrete return airborne lidar in Ghana forests.  ...  Lidar is a powerful tool to estimate aboveground biomass at fine resolution; however its application in tropical forests has been limited, with high variability in the accuracy of results.  ...  We are grateful to the Ghana Forestry Commission staff, to Justice Mensah and all the field collaborators.  ...

2018 Interface Focus  
One contribution of 12 to a theme issue 'The terrestrial laser scanning revolution in forest ecology'.  ...  Estimating the total mass of C stored in a tree requires measuring both the above-and below-ground (root) biomasses, via harvest and weighing.  ...  The biomass represents the accumulated productivity of the tree in terms of stored carbon (C) and, as a result, quantifying above-ground biomass (AGB) of trees on large scales is vital in order to estimate  ...

Monitoring and estimating tropical forest carbon stocks: making REDD a reality

Holly K Gibbs, Sandra Brown, John O Niles, Jonathan A Foley
2007 Environmental Research Letters  
Here we synthesize, map and update prominent forest biomass carbon databases to create the first complete set of national-level forest carbon stock estimates.  ...  While there are no practical methods to directly measure all forest carbon stocks across a country, both ground-based and remote-sensing measurements of forest attributes can be converted into estimates  ...  This work was supported in part by NASA and a US DOE Graduate Research Environmental Fellowship.  ...
