Biomass and carbon accumulation in a fire chronosequence of a seasonally dry tropical forest Export

@article{citeulike:1719154, abstract = {Abstract Seasonally dry tropical forests (SDTF) are a widely distributed vegetation type in the tropics, characterized by seasonal rainfall with several months of drought when they are subject to fire.

We quantified aboveground biomass and carbon pools of trees, lianas, palms, and seedlings, and belowground biomass and carbon pools (Oi, Oe, Oa soil horizons and fine roots). Total aboveground carbon ranged from 0.05 to nearly 67 Mg C ha-1, belowground carbon from 21.6 to nearly 77 Mg C ha-1, and total ecosystem carbon from 21.7 to 153.5 Mg C ha-1; all these pools increased with forest age.
