Reducing the age of maturity as a way to increase forest productivity and minimize risks in growing spruce stands

Abstract
Based on the results of the databases of forest management materials processing and the results of laying out test plots with felling of accounting trees it was established the advisability of switching from quantitative to technical maturity in the leased areas of large pulp and paper mills. The latter is calculated on the maximum yield of the most popular assortment of coniferous pulpwood. Establishing of technical maturity will allow reducing the cutting age in spruce stands leased for timber procurement by the JSC “Solikamskbumprom” from 81–100 to 61–80 years in plantings of quality class III or higher and from 101–120 to 81–100 years in plantings of IV quality class or lower.
This will not only ensure an increase in timber yield per unit of area, forest productivity, but also minimize the risk of spruce plantations dying from forest fires, strong winds and epiphytotics of pests and diseases, in particular the engraver beetle (Ipstypographus L.).
At the same time, reducing the cutting age will necessitate a transition from measures to promote natural regeneration to artificial and combined reforestation of spruce stands with mandatory implementation of agricultural and silvicultural care.
