Ryff L. Flora and Vegetation of Outcrops in the Mountainous Crimea

Research subjects: the structure of flora and vegetation on outcrops of different rocks in the Mountainous Crimea. Research objectives: the revelation of peculiarities of vegetation on different rock outcrops for working out conservative measures. Methods: methods of comparative study of flora, Braun-Blanquet's method of classification of vegetation, methods of estimation of nature protection significance of phytocoenoses, etc. Theoretical and practical results: The species composition of flora on different rock outcrops has been established and the comparative analysis of their systematic, arealogical, biomorphological and ecological structures have been carried out. On this basis the specific character of petrophyte flora depending on type of substrate has been determined. Classification and ordination of vegetation on outcrops have been fulfiled. Estimation of nature protection significance of petrophyte vegetation is given. Propositions about including of new species to project of the Red Date List of the Crimea and about widening of natural reserves fund of Ukraine are introduced. Novelty of introduced: For the first time the species composition of vegetation on outcrops in the Mountainous Crimea and distribution of petrophyte species for different types of rock have been determinated. The level of taxonomic richness and the degree of similarity of flora on outcrops of different types of rock have been established. 54 syntaxa (1 order, 10 alliances, 4 suballiances, 29 associations and 10 subassociations) which are new for science have been described, the prodrome of vegetation on outcrops in the Mountainous Crimea has been composed for the first time. A new species to the Crimean flora and new habitats of the number of rare taxa have been revealed. Implementation degree: The results of dissertation have been used in the report "Scientific basis of organization of territory, protection and utilization of complex natural monument "Meganom peninsula" and have been included in "Nature annals of reservation "Martian cape" (2002). Obtained information was inserted in "Fundamentals of general ecology" and "Geoanomalous zones and biota" lecture courses on the ecology department of Yalta institute of management Herbarium of the Nikitsky botanical garden - National scientific centre (YALT) supplemented by materials in petrophyte flora of the Mountainous Crimea in number of 350 sheets, including collection of 4 rare species which were absent in the Herbarium before. Effectiveness: optimization of environment state, increasing of effectiveness of nature conservation measures, improvement of quality of specialists training. Sphere, sector of implementation: theoretical botany, ecology, nature conservation activity, specialists training.
