| − | A stand register usually includes, in each stand, average values and totals for several variables. However, models applied in the simulations of growth, treatments, etc. need initial forest state descriptions at the single tree-level. If not obtained in a forest inventory, e.g. according to [[Ivent]], such data can be simulated. Other inventory methods, and other simulation techniques (e.g. sample plot imputation), are available. E.g., remote sensing like airborne laser sensors may soon return single-tree data for large areas without great costs, but of great interest. | + | A stand register usually includes, in each stand, average values and totals for several variables.
