Soil C concentration ranged from 0.12 to 14.55% and averaged
3.05 0.07%, while bulk density ranged from 0.28 to 1.59 g cm3
and averaged 0.83 0.02 g cm3. C density was highest (657.61 Mg
C ha1) in Rhizophora stylosa forests and was lowest (126.14 Mg
C ha1) in the Kandelia candeleA.corniculatum þ Avicennia marina
forests. The average density of top 1 m soil C among forest types
was 270.39 76.25 Mg C ha1, and soil C in all sites together was
5.65 0.54 Tg C, which represented 81.74% of the total C stocks
