Taluses and Downfall Slopes as Geomorphological Refugia of Flora Relict Endemics of the Mountain Crimea and their Modern Phytoindication

Abstract In geomorphology, slopes are defined as any kind of irregularities of vertical and subhorizontal surface. A slope is an inclined part of the earth’s surface, which steepness is sufficient to determine further development of relief as a single geomorphological complex over its entire surface. There were given the being heterogeneous geomorphologic structures, slopes and their azonal landscapes and the reasons for peculiarities of the ecological environment, the link of some rare species to specific relief microforms have. The study of this phenomenon is important for geomorphology, paleogeography, phytocenology, elaboration of measures for protecting rare species (relics, endemics, relic endemics).
