    Opis:
    Productive European beech stands (Fagus sylvatica L.) involving Scots pine (Pinus sylvestris L.) are formed in Ukrainian Roztochie. Considering value and limited distribution of beech stands involving pine in tree species composition, it is necessary to work out and implement measures for their natural restoration in connection with the climate change and the efficient use of raw materials and non-wood products. Main forestry and management indices of beech stands that include pine in tree species composition were analysed. Forestry activities that are currently carried out in middle-aged and maturing stands significantly reduce their relative completeness and growing stocks, as determined by comparing growth particularities of productive beech stands from different sources.

    Opis:
    As of 2019, the total area of forest stands with the varying proportion of Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.) in composition on the Ukrainian Roztochchia was 11,251.3 ha and the area of pine stands involving European beech in composition was 6879.5 ha. Pine stands involving beech in composition are formed on the fresh, moist and boggy relatively pure and relatively rich soil condition. Pine forest stands (average share of pine exceeds 56%), which include beech in composition occupy more than 80% of the total area of interest. Mature and overmature forest stands dominate most of the landscape. More than 85% of stands are characterized by an average relative completeness. Undergrowth of deciduous tree species, which is mainly formed by European beech or hornbeam (Carpinus betulus L.) and rarely by common oak (Quercus robur L.) or sycamore maple (Acer pseudoplatanus), is available under a canopy of middle-aged, ripening and mature stands. The study points to the need to rethink forest management approaches and eventually to use such methods of forest cuttings that ensure natural regeneration not only of a European beech and common oak, but primarily of a pine. The practice of creating pine plantations in such conditions favourable for its growth and development should be used only in those cases when it is impossible to achieve natural regeneration of pine.

    Opis:
    The utility of phytocenotic indices in the diagnosis and classification of forest sites might be limited because of vegetation degeneration in managed forests. However, even in secondary communities it may be possible to determine indicator species, although these may differ from typical and well known plant indicators. The aim of this work was to assess the vegetation diversity of Scots pine stands in representative forest site types along a moisture and fertility gradient. In total 120 sample plots from Turawa forests were included in the study. These plots represented young (21–40 years) and old (> 80 years) Scots-pine-dominated stands. The forest sites were categorized according to Polish site classification. Four site categories were studied: Boew (very nutrient-poor and mesic sites), BMoew (nutrient-poor and mesic sites), BMw (nutrient-poor and moist sites), LMw (quite nutrient-rich and moist sites). The species composition of the forest patches studied hardly differed among forest site types. Almost all of the vegetation in site Boew was different from both moist site types (BMw and LMw). Sites Boew andLMwhad the exclusive species determined as site indicators. Moreover, young stands had their own site type indicator species which differed from old stands. Numerical classification showed that only two plant communities were widespread: Leucobryo-Pinetum in Boew and BMoew, and the community of Pinus sylvestris and Molinia caerulea in BMoew, BMw, LMw. In secondary communities typical indicator species may not be useful, but it is possible to determinate species that are locally unique to forest site type. Despite the convergence in the composition of the plant community resulting from tree stand unification, plant communities have the capacity for a more diverse composition. Tree stand conversion can increase phytocenotic diversity.
