State of forest sites on the Karelian Isthmus 2 years after an outbreak of European spruce bark beetle and other wood pathogens was considered. Unpleasant environmental conditions weakened the stands, which supported wide distribution of pests. Sanitary cuttings worsened the state. We evaluated forest health and recommended the ways of improvement. Spruce was the dominant specie on all the sites under study. European spruce bark beetle populations and lower amount of other ones, including double-spined bark beetle, sixtoothed spruce bark beetle, Norway spruce weevil, sawyer beetles, and black spruce beetle were found on most of the trees. The wood pathogens distribution were of fungal origin, coming out from diffuse centers of chronic cancerous growth. Its infestation exceeded 50% on some sites. However, no diseases provoking mass degradation of spruce were found. Trunk pests and phytopatogenic fungi have not represented a hazard for the stands. The end of an outbreak and stable density of pest populations were due to the ratio of bark beetle reserves to increment, growing number of enthomophags and illness of pests. Based on data and calculation we conclude that the mass outbreak of pests has finished. We recommend to stop sanitary cuttings to reduce injuries of the trees, forage for trunk pests, and environment favorable for the distribution of cancer.
