Distribution of Forest Aboveground Biomass

Figure 6


This figure appears in the Our Changing Planet: The U.S. Global Change Research Program for Fiscal Year 2012 report.

a. Forest aboveground biomass (ABG) is mapped at 1-km spatial resolution. The study region was bounded at 30° North latitude and 40°South latitude to cover forests of Latin America and sub-Saharan Africa, and from 60° to 155° East and West longitude. The map was colored based on 25 – 50 Mg/ha AGB classes to better show the overall spatial patterns of forest biomass in tropical regions. Histogram distributions of forest area (at 10% tree cover) for each biomass class were calculated by summing the pixels over Latin America in b. Africa in c. and Asia in d. Similarly, total AGB for each class was computed by summing the values in each region with distributions provided for Latin America in e. Africa in f. and Asia in g. [Mg = Million metric tons].
