UNFCCC: A/R Methodological Tool

Calculation of the number of sample plots for measurements within A/R CDM project activities.

This UNFCCC tool can be used for calculation of number of sample plots required for estimation of biomass stocks from sampling based measurements in the baseline and project scenarios of an A/R CDM project activity. The tool calculates the number of required sample plots on the basis of the specified
targeted precision for biomass stocks to be estimated. For the purpose of this tool all parameters used in calculation of plot level biomass stock (e.g. biomass expansion factors, root-shoot ratios) are considered fixed constants. Similarly, all models used for calculation of plot level biomass stock (e.g. volume tables or equations, allometric equations) are considered to be exact.
