Predicting carbon sequestration of woody biomass following land restoration

摘要: Abstract Land restoration through planting native species or facilitating natural regeneration may provide opportunities for sequestration of biomass carbon in many regions where woody vegetation has been cleared largely supressed. Australia provides a good case study how from these activities be simulated at national- and project-scales using an empirical full accounting model; FullCAM. Recent work resulted 1.6-fold increase calibration sites available, while the underlying input layer site productivity also recently refined. These developments provided opportunity to expand domain application capability model. We collated 2340 observations above-ground planted naturally regenerated stands across applied novel technique correct baseline existing remnant trees shrubs within (typically  1500 stems per hectare) stand density; (iii) belt plantings lower (iv) blocks on land used deliver environmental services, and; (v) occurring livestock production. Compared regeneration, yields after 30 years growth were 1.3- 2.2-times higher plantings, mesic accessing ground surface water, e.g. riparian floodplain zones. After when compared fenced-off conservation, 1.5-times that continued managed In revising model calibrations, trade-off between accuracy utility was considered. By only age, five categories, overall efficiency prediction 68%. Additional explanatory variables such as stocking densities with block configuration, establishment method, mix, width tested, but their addition considered unwarranted, given additional resources required account inputs would substantial, they
