  • 5 Dendrological Diversity in Santa Marina Holiday Village
    Silva Balcanica, 19(1)/2018 DENDROLOGICAL DIVERSITY IN SANTA MARINA HOLIDAY VILLAGE - SOZOPOL AS AN EXAMPLE OF CONTEMPORARY LANDSCAPE DESIGN TRENDS IN BULGARIA Svetlana Anisimova Faculty of Ecology and Landscape Architecture, University of Forestry – Sofia Abstract The paper presents dendrofloral characteristics of Santa Marina Holiday Village, situated on the Southern Bulgarian Black Sea coast. The systematic structure and species composition of woody ornamentals, the absolute and relative quantitative participation of each species were analyzed. A total number of 227 woody species, 315 species and intraspecific taxa, respectively of 110 genera, belonging to 54 families, were recorded. Furthermore, 44.4% of the families were represented by only one species. The results indicate a significant tree and shrub diversity, competitive with the one displayed in some Bulgarian historical parks famous for their dendrological collections. Some of them have been rarely cultivated in the green spaces in Bulgaria so far. A trend of a large scale use of alien species and cultivars was established. Consequently, the participation of autochthonous species is insignificant (5.9%). A relatively high percentage of coniferous and evergreen woody species provides the constant ornamental effect of the holiday village green spaces. Key words: urban green spaces, alien species, woody ornamentals, landscape planning INTRODUCTION The ornamental tree and shrub vegetation plays a leading role in the landscape design, creating the volume-spatial composition and enhancing environmental aesthetics and expressiveness. All ecosystem services provided by woody species depend on their adaptability to extreme environmental conditions (Chen, Jim 2008). In recent years, the diversity of ornamental tree and shrub species and cultivated varieties has grown considerably (Knapp, 2010; Chalker-Scott 2015; Sjöman et al., 2016.).

  • 66 FOLKLORICA 2013, Vol. XVII Mythological Thinking and Archetypes in the Contemporary Bulgarian Nestinarski Ritual Complex
    66 Mythological Thinking and Archetypes in the Contemporary Bulgarian Nestinarski Ritual Complex Ana Stefanova Institute of Ethnology and Folklore Studies and Ethnographic Museum (IEFSEM) Bulgaria, Sofia Photographer: Svetlan Stefanov, Bulgaria Abstract The paper examines mythological thinking in the contemporary performance of the ancient ritual complex of nestinarstvo in Bulgaria. As the folk tradition is transformed into freshly “invented” forms in the village of Stomanevo, it has been influenced by “external” factors such as individual cultural elements as well as by globalization, in particular easy access to information and the flow of esoteric literature into Bulgaria in the aftermath of communism. The rite is further molded by distinct psychological factors that constitute fundamental and dynamic conditions necessary for the tradition to be preserved and to evolve. This ritual is a living example of a community phenomenon with roots in the collective unconscious and based on archetypal structure. While its “outer” traits may vary, the “core” remains the same, representing a mosaic of universal values anchored in space and time. The paper examines mythological thinking in a contemporary performance of the ancient ritual complex of nestinarstvo in Bulgaria. (1) As the old tradition has been transformed into newly “invented” forms (2), it has been influenced by “external” factors such as individual cultural elements and globalization, represented by easy access to information and the flow of esoteric literature into Bulgaria in the aftermath of the fall of communism. These trends are further molded by distinct internal psychological determinants, which make up basic dynamic conditions required for a tradition to persist and to evolve.

Introduction to specific problems of the area The marine spatial plan for Mangalia-Shabla area was conceived as a pilot project included in MATSPLAN -BS project in order to test the capacities of the two countries to develop and adopt a concrete instrument for the management of the marine area. This plan takes into consideration the existing data describing the processes of the natural marine areas as well as the human activities developed in this area in order to establish balance between human actions and ecosystems subsistence. The plan is meant also to to put into practice the EU Directive for MSP, creating an institutional framework for MSP implementation in Romania and Bulgaria, enhancing the cross-border cooperation and exchange of information between the two countries. 1.1 Plan area delimitation The spatial plan area is located at the border between Romania and Bulgaria, its delimitation took into consideration two types of zones: the territorial waters (the management area) and coastal area and EEZ (the extended analyse area for the study of interactions).
