Relevance of the study is determined by the absence of the government approved method of state cadastral evaluation of forestlands and major divergence between methods of private valuation agencies. The main aim of the study is to develop the method of cadastral evaluation of forestlands which can consider individual aspects of minimal inventory items - stratums. It should be acceptable for every region of Russia and should be based on considering all usable types of forest resources which can be harvested in region. Among other issues, calculating cadastral value we should consider annual growth of inventory indexes, for example timber volume, because forestland evaluation should be provided to the moment of mail felling not to the moment of inventory. The methods used in the study. Cash flow discounting method is used for cadastral value calculation. Regression analysis is used to determine the dependence between inventory indexes and forest resources fertility. Geographic informational modeling using MapInfo is carried out for visualization of results and their verification. The result of work is the automate method which allows determining forestland cadastral value by stratums using forest inventory data. The result of the method approbation is per unit cadastral value indexes which correspond to normal distribution by frequency. Also ground location of stratums with the determined cadastral value corresponds to stand structure and timber volume per hectare. The method is approbated on the forest inventory data of one of Leningrad region forest districts considering regional aspects.
