Stratified variance in the AGB maps and the RadamBrasil AGB field data within geomorphology and soil maps. Stratified variance (red color scale) in the AGB maps and the RadamBrasil AGB field data within each class of the geomorphology and soil maps. a Geomorphology of the Legal Amazon map (MMA 2006b); b relief map 2002 (IBGE 2002b); c relief units map of Brazil (IBGE 2006); d soil carbon stocks map (Bernoux et al. 2002); e soils of the Legal Amazon map (MMA 2006b); f soil map (Quesada et al. 2011) and g soil map of Brazil (IBGE 2001). The 6 largest classes and the percent of the class areas are shown in the legend, and the total number of classes is below each environmental factor map. A detailed legend of all the classes of each environmental factor map is provided in A2. LAC: soils with low activity clay, HAC: soils with high activity clay, V1: open Amazon forest and V2: dense Amazon forest
