Fig. 2: Importance ranking of environmental and disturbance drivers on secondary forest regrowth grouped by climatological regions.
From: Large carbon sink potential of secondary forests in the Brazilian Amazon to mitigate climate change
a Regions are grouped according to similarities in Maximum Cumulative Water Deficit (MCWD), annual average downward shortwave (SW) radiation and annual average precipitation. See Supplementary Table 9 for quantitative interpretations of the regions. The average importance ranking for each of the six variables, as well as Forest age, is shown for b the North-West region, c the North-East and Central-North region, d the South-West and Central region, and e the South-East and North region. The average ranking was calculated following 30 iterations of a conditional random-forest model. The importance has been ranked from least important (1) to most important (7) and the vertical dotted line separates environmental drivers (left) from anthropogenic disturbance drivers (right). The error bars in b–e denote the 95% confidence interval. The abbreviation SCC in b–e refers to Soil Cation Concentration.
