Degradation in carbon stocks near tropical forest edges. Nature Communications 2015 6 Article number: 10158 doi:10.1038-ncomms10158
Abstract
Carbon stock estimates based on land cover type are critical for informing climate change assessment and landscape management but field and theoretical evidence indicates that forest fragmentation reduces the amount of carbon stored at forest edges. Here using remotely sensed pantropical biomass and land cover data sets we estimate that biomass within the first 500 m of the forest edge is on average 25% lower than in forest interiors and that reductions of 10% extend to 1.5 km from the forest edge. These findings suggest that IPCC Tier 1 methods overestimate carbon stocks in tropical forests by nearly 10%. Proper accounting for degradation at forest edges will inform better landscape and forest management and policies as well as the assessment of carbon stocks at landscape and national levels.
