Extended Data Fig. 8: Quantification of AGB when depth of edge influence is defined as 75th percentile of the distance to the edge.
From: A globally consistent negative effect of edge on aboveground forest biomass
a, Depth of edge influence in meters at grid cell level. b-c, AGB loss due to edge effects at grid cell level (b) and biome level (c). AGB loss is defined by the difference between observed and expected AGB assuming that edges show the same biomass density as nearby forest interiors. For (c), the percentage in brackets shows how low the observed AGB is compared to the counterfactual AGB. Mean depth of edge influence values were: 320 m (global), 767 m (tropical/subtropical), 235 m (temperate), and 262 m (boreal). Total AGB loss was: 52 Pg (95% CI: 44–61 Pg; 8% of total biomass) globally, 24 Pg (95% CI: 20–28 Pg; 6%) for tropical/subtropical, 10 Pg (95% CI: 9–12 Pg; 9%) for temperate, and 8 Pg (95% CI: 6–9 Pg; 11%) for boreal forests.
