Trees in the densely built-up historical cores of cities play an important role in increasing the aesthetic values of the cityscape as well as lowering the effect of the urban heat island. The research aimed to determine the spatial distribution of tree populations in the medieval parts of cities according to local policy. The investigation included three cities in Central and Eastern Europe: Poznań and Lublin in Poland and Lviv in Ukraine. The oldest parts of these cities share similar origins, the same continental biogeographical region, and comparable climatic conditions.This study considered indicators of occurrence, density, species composition, and spatial distribution; and the number of trees planted since the political transition to democracy has also been considered, taking into account the composition of their species. Local policy documents on greenery management, revitalisation, and adaptation to climate change were analysed.The study identified different types of management concerning trees. In Poznań, trees are actively introduced in public spaces, but private backyards are managed by their owners. In Lublin, although there are relatively few new plantings, there is the largest share of trees in the backyards and self-seeding is common. In Lviv, there are new plantings in private and public spaces. Lviv is distinguished by its large share of native trees, with naturally shaped crowns, and in Poznan and Lublin, new plantings include artificially shaped, small spherical crowns. The local policy documents don't contain operational directives regarding the cultural, environmental, social, and technical conditions for new planting.

The article is devoted to the study of the development of ecotourism in the protected areas of the Transcarpathian region. The peculiarities of ecotourism development in the period of globalization are considered and the insufficient involvement of nature protection territories and their potential for the development of domestic and international tourism is pointed out. The problem of poor implementation of sustainable tourism forms is singled out. The main accents of the relationship “urban society – holiday-maker (tourist) – environment” have been identified. A number of works of domestic scientists, legislative, normative- legal, strategic and program documents regulating tourist movement within the protected areas are analyzed. The essence and potential of the studied territory on the possibilities of ecological tourism development and preconditions for the functioning of ecotourism infrastructure have been revealed. The structural elements of ecotourism infrastructure have been singled out, namely: ecological and educational trails, tourist routes, visit-centers, information tourist points and centers, specially equipped zones, historical and culturalobjects, accommodation and catering establishments, etc. For example, a detailed analysis of the ecotourism infrastructure of the National Park “Synevyr” located within the Carpathian region of the Transcarpathian region has been given. On the basis of a thorough analysis the natural, historical and cultural attractions have been studied and the most popular tourist routes within the research area have been identified. In addition to interesting tourist sites (natural or historical and cultural), the current state of ecological trails and tourist routes, as well as the mode of their use has been determined. The main problems and limiting factors of tourism use are used and conservation of protected areas have been described. A detailed characteristics of the National Park “Synevyr” functioning has been given and the latest material of natural, historical and cultural attractions, ecological and educational trails and tourist routes have been collected and analyzed. It is proved that within the studied area the village Kolochava is the most popular tourist destination with proper infrastructure and information and advertising support. We have proposed a number of recommendations on encouraging and regulating of tourist traffic, improving of ecotourism infrastructure, optimal territorial management and the approximation of protected areas to the requirements of sustainable tourism development in the protected areas of the Transcarpathian region.
