The paper reviews research papers, develops recommendations for forest regulatory documents. Some deficiencies in the current regulatory framework are revealed. Traditionally, the system of normative documents had a hierarchical structure. The upper level contained basic principles and the most general provisions, while regional level documents focused on local features of forest growth, and also analyzed possible differences within the region. In addition to the geographical aspect, progress in the development of forestry practices, new scientific data and gradual changes in the forest fund were also taken into account, which encouraged periodic updating of standards. The last time it happened more than 20 years ago. The current standards regulating the main stages of forest growing – reforestation, forest care and felling of mature tree stands – are considered. Specific examples illustrate problems, caused by the imperfection in forest legislation, insufficient study of natural and economic characteristics of the regions, progress in the development of logging equipment and considerable changes in the forest fund. It is pointed out that there is a need for normative measures for recording the costs of carrying out activities. It is noted that these shortcomings are a consequence of neglect of the principal issues of domestic forestry. It is shown that system for assessing stand thinning quality is imperfect and the interpretation of the results of the work is ambiguous. It is proposed to base the assessment on absolute indicators, as is accepted in international practice. The urgent need to plan biodiversity conservation activities taking into account the peculiarities of natural and territorial complexes is shown. We suggest to improve the situation, with proposals aimed at creating conditions to intensify forestry production and restore resource potential of taiga forests.

In this paper, for the first time in Russia we report on four new occurrences of the rare xylarialean ascomycete Chlorostroma vestlandicumrevealed in the course of mycological surveys of the Northwestern European Russia. Description and colour illustrations of the material studied are provided. Dutch Elm Disease as the major possible threat for the species is discussed. The species is recommended for inclusion in the next editions of the regional Red Data Books of Leningrad, Novgorod, and Pskov Regions.

The paper deals with the main achievements of scientists of M.M. Gryshko National Botanical Garden of the NAS of Ukraine (NBG) in scientific, conservation, cultural and educational activities. The results of researches on biodiversity, conservation, plants protection, introduction, acclimatization and selection, allelopathy, medical botany, landscape design, bioindication and hemosystematycs are given. It is noted that over 14 thousands species, forms and varieties of plants, are collected in NBG, and the most unique collections attributed to the objects of national heritage. Breeders have obtained more than 300 certificates or author ship on plant varieties. NBG carries out extensive international cooperation, several new exposition of plant collection appeared in Botanical Garden. In recent years the achievements of NBG scientists were awarded by two State Awards in the field of science and technology of Ukraine.
