5.2.2 Dead wood and litter pools
Tables 3.2.1 and Table 3.2.2 in GPG2003 (1) provide some default data on the deadwood and litter pools. For the purposes of REDD+ estimation, emissions and removals associated with REDD+ activities, carbon stock changes within these pools need to be obtained by sampling, ideally from the same sampling sites established for biomass estimation. If methods for estimating these pools are not already established, e.g. via a NFI, countries could apply the methods set out by the UNFCCC for use with afforestation and reforestation projects under the Clean Development Mechanism(2).Tier 3 methods utilise mass-balance models that encompass all carbon pools including the deadwood and litter pools as well as the movements between all pools (Box 11). In such cases countries would have models calibrated to develop estimates for the deadwood and litter pools consistent with their identified forest strata.
