Abstract. The technique of obtaining reliable data on the state of preliminary reforestation using the electronic database of the forest area is described. The analysis of the undergrowth is based on the use of an electronic database, formed from the taxonomic descriptions, in the «Microsoft Office Excel 2016» spreadsheet. The use of the current normative documents in combination with the correctly compiled database of the forest area will allow us to analyze the provision of pre-generation undergrowth in a forest area of unlimited area with minimal labor. The obtained data will allow to estimate each allocation and to obtain general statistics for the entire analyzed area. Two methods for analyzing the quantitative indicators of pregrowth undergrowth are proposed in the article. The advanced technique describes the possibility of analyzing the amount of pregrowth undergrowth at each site, followed by the generalization of the obtained data to summary tables throughout the analyzed site. The use of an advanced method of analysis will provide data on the required method of reforestation according to the criteria of the current regulatory documents. The high-level technique is described on the basis of the criteria of undergrowth for the Middle Urals taiga region with a description of the principle of the formation of criteria for other areas. To establish the laws of accumulation of adolescence, it is recommended to use the methodology for evaluating the potential for reforestation, the entire volume of the database is analyzed according to the average value of the density of adolescence. The use of the proposed methods will reduce labor costs in the analysis of electronic databases by several times in comparison with manual analysis in a spreadsheet and hundreds of times compared to the analysis using paper taxation descriptions.
Keywords: undergrowth, taxation descriptions, database, availability, reforestation.
