Fig. 3: The effect of disturbance on region-specific regrowth models of carbon accumulation in secondary forests.
From: Large carbon sink potential of secondary forests in the Brazilian Amazon to mitigate climate change
The secondary forest regrowth models are shown for the regions identified in Fig. 2a. In each region, the climatological variables of Maximum Cumulative Water Deficit (MCWD), annual average shortwave radiation and annual average precipitation are: a North-West region, b North-East and Central-North region, c South-West and Central region, d South-East and North region. The legend colours represent percentage of secondary forests that are affected by the type of disturbance in each region prior to regrowth, namely: blue—No disturbance (“Single deforestation, Not burnt”), green—Only fire disturbance (“Single deforestation, Burnt”), orange—Only deforestation disturbance (“Repeated deforestation, Not burnt”), purple—Both disturbances (“Repeated deforestation, Burnt). Shading denotes the 95% confidence interval of the models based on the median value of the initial data for each age—dots in figures. See Supplementary Table 9 for quantitative interpretations of the qualitative definitions given here, for example “Low precipitation”. The abbreviation SCC in a–d refers to Soil Cation Concentration.
