Abstract
The results of the investigation of sanitary conditions of stands in the territory of nature reserve fund of state enterprise «Tsumanske Forestry» and substantiation of forest sanitation are examined in the article. The research has revealed a mass dieback of trees in stands with Norway spruce, Scots pine and common alder predominating in composition. Direct causes of dieback of trees are determined: Norway spruce is damaged by bark beetle Ips typographus L., Scots pine is damaged by Phellinus pini (Brot.:Fr.) and vascular mycosis; for alder, it is overmature age plus abnormal dry weather in autumn 2014. Hypothesis relative to the source of Norway spruce dieback was derived: In our view, this is a discrepancy between the tree species and forest vegetation zone. Since the stands examined lost their bioresistance completely, the recommended measures for forest massif sanitation are clear sanitation fellings combined with forest plantation creation or assistance to forest natural regeneration.
