Систематичний аналіз флори Національного природного парку “Гуцульщина” та її репрезентативність для природозаповідного фонду Карпатського регіону

Abstract

It was discovered that flora of the National Natural Park “Hutsulshchyna” consists of 836 species of higher vascular plants which belong to 411 generas, 111 families and 5 divisions. Magnoliophyta dominate -94,3%, Magnoliopsida to Liliopsida ratio is 1:3 which is characteristic of Central Europe flora. Ten leading families of the NNP “Hutsulshchyna” include 209 genera and 455 divisions, the rest 45,4% of divisions belong to 102 families. The flora ratio is 1:3,7:7,5; an average number of divisions in a genus is 2,0; the number of genera in a family is 3,7. The NNP’s flora ratio is close to Central Europe’s. Asteraceae and Poaceae families take the leading position in ranges of flora. Rosacea family is in the third position, which indicates typical Central European flora. The ratio of Asreraceae to Lamiaceae is 3,0, which is typical of Boreal and Nemoral areas flora. (2,5-3,8). The ratio of Asteraceae to Fabaceae in the NNP “Hutsulshchyna” is 2,2. The transition from Boreal flora area to Mediterranean can be demonstrated by the range the Karpatskyi NNP - NNP “Hutsulshchyna” - NNP “Vyzhnytskyi”, which corresponds to their location from north-east to south-west and to transition from mountainous to plain flora types. So our systematic analysis confirms that the Park’s flora is typically Central European with distinct Boreal traits. We present comparative characteristics of the flora of NNP “Hutsulshchyna” and the adjacent NNP “Vyzhnytskyi” and Karpatskyi NNP. The comparison of the indices of systematic structure of the investigated flora with floras of Boreal and Middle European regions is shown that more than half of the main indicators of the NNP "Hutsulshchina" coincide with the indicators in the flora of Boreal region.
