-Plot values of target variables representing changes (e.g. change of carbon stock in above ground biomass) or dynamics (e.g. gross increment or the mount of cuttings) cannot be obtained by using data of one reference-year-set only. For such variables plot data collected at two survey occasions is needed. Therefore, they have to be attached to a pair of reference-year sets, which is represented by a specific reference-year set (indicated by _status_variables_ set to f).
