mosaic restoration may be easier to undertake as it allows a greater range of land uses whilst restoring areas to closedcanopy forest is likely to remove more c per unit of area depending on ecosystem type and whether the result is a natural forest or a plantation areas converted to forest are estimated to remove between about and tco per ha per year in above and belowground biomass from default data in ipcc the ipcc states with high confidence that increased atmospheric co will lead to increased terrestrial carbon uptake ciais et at and a recent review suggests that the largest increase has been in woody biomass within savanna included in some national forest definitions and nonforest ecosystems liu et at carbon sink figures for existing forests are not included in the technical potential for reduced deforestation given here as a result of the uncertainty surrounding how carbon sinks and their capacity to absorb c will change in the changing climate bellassen and luyssaert
