An assessment of the carbon stocks and sodicity tolerance of disturbed forests in Southern Vietnam.

Background: In the lower Mekong Basin and coastal zones of Southern Vietnam, forests dominated by the genus have two notable features: most have been substantially disturbed by human activity and can now be considered as degraded forests; and most are subject to acute pressures from climate change, particularly in regards to changes in the hydrological and sodicity properties of forest soil.

Results: Data was collected and analyzed from five typical stands including: (1) primary forests on sandy soil (VS1); (2) regenerating forests on sandy soil (VS2); (3) degraded secondary forests on clay soil with peat (VS3); (4) regenerating forests on clay soil with peat (VS4); and (5) regenerating forests on clay soil without peat (VS5). Carbon densities of VS1, VS2, VS3, VS4, and VS5 were found to be 275.
