Biodiversity of high-mountain woody plants in the East Carpathians in Ukraine

The highest parts of the European mountain massifs are covered by subalpine and alpine vegetation, with rich flora containing many relic woody plants adapted to cold temperatures relatively short vegetation periods. In Ukrainian Carpathians, only several form environmental conditions suitable for high plants. aim study was detection centre biodiversity in East Carpathians Ukraine. We expected largest number species would occur Chornohora, most elevated chain country. To solve this problem, geographic distribution 16 analysed cartographically. gathered georeferenced data 919 localities taxa, which belts, prepared maps their using QGIS software. Additionally, we vertical occurrence on different expositions every taxon. Most massifs. mainly massifs, Svydovets, Chyvchyny, Marmarosh, a lesser extent, also Gorgany. predominant northern or close indicate demands level humidity soil precipitation. These condition point character species, origin from glacial periods Pleistocene. have centres sub-alpine belts Ukraine territory valuable but threatened elements flora.
