Before cut is the approximate volume of all merchantable trees in the well-stocked stand at the average stand diameter shown in column 1. After cut is the volume of ﬁleave trees,ﬂ properly spaced and selected on the basis of species, form and vigor, to remain throu gh the next cutting cycle. Forest inventory is the systematic collection of data and forest information for assessment or analysis. An estimate of the value and possible uses of timber is an important part of the broader information required to sustain ecosystems. The forest stock volume (FSV, m3 ha-1) is the sum of the stem volumes of all the living trees per unit area, and is one of key forest variables for forest resources management and assessments on local, region and country scales . FSVs have a strong relationship with the aboveground biomass (AGB) and carbon stocks .
