Forestry development in Kazakhstan is negatively affected not only by negative anthropogenic factors (fires, windfalls, etc.), but also by some changing natural biological conditions, for example, epiphytotic diseases or outbreaks of mass reproduction of dangerous and quarantine forest pests, the invasion of which threatens the complete degradation of forests. In this regard, research on lepatopathological monitoring and forest protection measures necessitates their implementation at a high scientific and methodological level. Especially in the protection of rare and endangered species as Betula Jarmolenkoana Golosk. The purpose of the work is to assess the current forest pathological state of Schrenk spruce and Yarmolenko birch plantations at public state organization «Narynkol forestry» of the Almaty region.
The article presents the results of forest pathological examination of forest plantations in the territory of the MGA «Narynkol forestry». To conduct the surveys, monitoring areas were laid down and cards were compiled for each area with a complete description of the state of the trees, taking into account age, morphological indicators, population with dominant pests, and tree species; diameter, height, age of the tree, sanitary condition, the main types of pests and diseases.
