The trends of development and increment of individual trees, as well as the productivity of beech coppice stands in the region of Crni Vrh were studied. The trees in the category of 20% of the largest-diameter trees in the stand were analyzed by the standard dendrometric analysis, the productivity was assessed based on the values of the major taxation elements measured at the sample plots. The results of these analyses, combined with the results reported by other authors, who studied beech coppice forests at the same locality but from different aspects, enable the real and comprehensive assessment of the state of these stands. On this basis, the aim of long-term management (conversion into a high silvicultural form) and the actual silvicultural measure (high selection thinning) were defined.

The purpose of the study is to analyze the sanitary condition of tree and shrub vegetation on the territory of school No. 19 in the city of Yoshkar-Ola. This work is relevant, since the school is a place for long-term stay of children of school and preschool age and the natural environment is an integral part of their educational activities. To determine the assessment of the state of the stand, the coefficients of the state of plants are calculated: the states of individual trees are determined by the external signs of a 5-point scale. Next, the coefficients of the state of the tree species are calculated according to the corresponding formula. The coefficients of the state of the stand as a whole are also found as the arithmetic mean of the coefficients of the state of individual tree spe-cies. As a result, an assessment of the state of the stand according to this gradation was deter-mined. Woody plants growing on the territory of secondary school No. 19 in Yoshkar-Ola were examined. A total of 35 species of coniferous and deciduous plants have been identified. Most species are characterized by a weakened state. Plants of hawthorn-blood-red, poplar × 'Soviet Py-ramidal', prickly plum and mountain ash are the most weakened. The condition of the plantings as a whole is assessed as weakened. It is recommended to carry out agrotechnical measures for plants and cleaning of dead specimens.

This paper presents the comparative analysis of stand state, productivity and silvicultural demands in beech stands of mixed origin, with a predominating percentage of trees of coppice origin, in different site and stand conditions, in the area of Cestobrodica and Straza. The main cruising elements were analyzed in three ecological units: Number of trees, basal area, volume, volume increment, mean stand diameters and height and the development of individual trees. The differences of the study ecological units, presented through the values of cruising elements and the phases of diameter, height and volume development of individual trees, are computed by the analysis of variance and LSD test. The analysis and the concluded significant differences enabled the real and comprehensive understanding of the state of these stands, based on which the long-term objectives of forest management were decided (conversion into a high silvicultural form) and actual silvicultural demands and measures - high selection thinning.

The purpose of the article is to reveal the particularities of special tactical training of future officers of the State Border Guard Service of Ukraine in the departmental institutions of higher education. The Special Tactical Training is understood as training of the officers of the State Border Service of Ukraine to act with weapons in various situations of operational and service activity. The discipline allows to perform comprehensive assessment of cadets’ readiness to carry out service duties for the protection of the state border, including the specifics of mobile units’ missions. To create real-life conditions, airsoft equipment and interactive shooting complexes of the "Laser Tag" type, multimedia shooting complexes, etc. are widely used. The results of the study confirm that the conditions for conducting such training in the border guard higher education institutions should be brought closer to the real situations, taking into account the specifics of operational and service activity at the border.
