Distribution of Pulsatilla Grandis Wender. (Ranunculaceae) in Ukraine

Abstract

Pulsatilla grandis Wender is included into the Red Data Book of Ukraine [13], Annex 1 of Bern Convention [4] Conservation status – LC. The results of phytocoenosis features of researching of growing P. grandis in different parts of natural habitat in Ukraine are presented. Database creation and primary studying of the received results were carried out by means of software Turboveg, analysis and classifi cation – by means of software Juice 7.0. Syntaxonomical scheme was composed on the basis of «Syntaxonomy of vegetation of Ukraine», which was developed by W. Solomakha [26]. It is specifi ed that on the major part of its natural habitat the grouping which includes P. grandis is mostly presented by the same or similar associations. There are three types of vegetation which include this species: meadow steppes and steppe meadows, petrophyte groupings and light thinned out forests. The descriptions prove that in Ukraine species belongs to different associations of Festuco-Brometea, Rhamno-Prunetea, Koelerio-Corynephoretea, Vaccinio-Piceetea classes. According to the literature, P. grandis also found in Trifolio-Geranietea sanguinei, Quercetea pubescenti-petraeae classes. The natural habitat has undergone regressive changes. In other European countries this species occurs in four classes: Nardo-Callunetea, Festuco-Brometea, Trifolio-Geranietea sanguinei, Vaccinio-Piceetea.The growing areas of P. grandis near the eastern border of the natural habitat in Ukraine are sensitive to the impact of anthropogenic factors. The main reasons for the disappearance of species of natural flora Ukraine is natural and anthropic impact. Examples of human impact is tearing, digging, trampling plants, grazing, mowing, burning, building and expanding the boundaries of settlements. The natural impact is manifested in the low competitiveness of the type and long period of ontogenesis.

Pulsatilla grandis Wender внесена до Червоної книги України (Kahalo, Korotchenko & Lyubinska 2009) і Додаток 1 Бернської конвенції (Бернська конвенція 1979). Природоохоронний статус – LC. Представлено результати дослідження особливостей фітоценозів в яких зростає P. grandis в Україні. Результати фітоценотичного дослідження оброблені за допомогою програмного забезпечення Turbo veg та Juice 7.0. Синтаксономічна схема була складена на основі «Синтак сономії рослинності України», яку розробив В. Соломаха (2008). Наведені нами описи доводять, що в Україні вид входить до різних асоціацій класів Festuco-Brometea, Rhamno-Prunetea, Koelerio-Corynephoretea, Vaccinio-Piceetea, а за літературними даним вид зростає у класах Trifolio-Geranietea sanguinei, Quercetea pubescenti-petraeae. В інших європейських країнах вид виявлено у класах Nardo-Callunetea, Festuco-Brometea, Trifolio-Geranietea sanguinei, Vaccinio-Piceetea.
