The above-ground C stock was estimated from mangrove tree and
downed woody debris biomass. Tree biomass wascalculated using allometric equations
(Table 1). The tree C pool was calculated by multiplying tree biomass with wood C content. Volumeand mass of the downed woody debris were calculated using the equations reported by
Kauffman and Donato (2012). The downed woody debris C pool was
calculated as the product of the downed woody debris mass multiplied
by the C content.
