Fig. 3.9 Above- and belowground carbon pools in Indo-West Pacific mangroves, assessed by
distance from the seaward edge of the mangrove forest in (A) estuarine mangrove forests situated
on large alluvial deltas and (B) oceanic mangroves situated in marine-edge environments (for
example, on island coasts). Belowground carbon accounts for 71–98% of ecosystem carbon at
estuarine sites and 49–90% at oceanic sites. Overall carbon storage does not vary significantly with
distance from the seaward edge in either setting over the sampled range (P > 0.10 for aboveground,
belowground, and total carbon storage by functional data analysis; 95% CIs for rates of change
were between −1.2 and +3.9 Mg C ha
−1 per m distance from the seaward edge, and all overlapped
zero). (The figures are reproduced from Donato et al. (2011) and are reprinted with permission
