Investigation of ecotones as uncial habitats of plant diversity is an actual problem of ecological researches. Based on a detailed analysis of the habitats of two rare and endangered, relic, and endemic species of the European flora Daphne sophia Kalen (Thymelaeaceae) and Syringa josikaea J. Jacq. ex Rchb. (Oleaceae), the confinement of these species to ecotones are revealed. The patterns of the formation, organization, and development of the ecotones as unical habitats of rare and endangered species are established. The tinning of some rare species to ecotones is specified linear or tipe spatial structure of their populations. The anthropogenic pressure leads to a transformation of linear populations to local isolated ones. So, to prevent the extinction of rare species from ecotones, their populations need to be under protection. At the same time, it is necessary to carry out the environmental management and the monitoring the state of population.
