Abstract
The article presents the results of an assessment of the state category of spruce (Picea obovata Ledeb.) stands on the territory of the Republic of Bashkortostan The state category, phytopathogenic load and local damage by forest pests were determined. The state category was determined in accordance with the obtained practical score, focusing on the scale of the sanitary state of the stand. On the basis of the data obtained, an analysis of the weighted average estimates of the state category of dark coniferous forests with various shares of spruce was carried out. Based on the results of the statistical analysis, it was revealed that the forest pathological state of spruce stands did not depend on the share of spruce in the stand composition. Significant differences in the state category of spruce were found in contrasting forest types; in other growing conditions, no significant differences were observed. Timely forestry measures aimed to improve the state of forest stands can increase the average score of the state category by 0.5-0.7, which will allow them to be transferred to the category of stands with high biological resistance, and to conduct systematic and rational forestry.
