Typha shuttleworthii in Ukraine and adjoining regions: tendencies of dynamics of distribution, ecological and coenotic peculiarities

Abstract

We present the results of analysis of the distribution of Typha shuttleworthii Koch & Sonder and tendencies of dynamics of its distribution in the Ukraine and adjoining regions. We regard T. shuttleworthii as a vulnerable taxon throughout Ukraine and adjoining regions, and the problem of conservation of its scattered localities is part of the problem to improve the hydrological balance and protection of river basin water resources. We established that until the 1990s this species had become rare in countries of the Carpathian Region, and during the last 10 to 15 years its natural habitats were situated mainly within protected areas. In particular, in the Ukrainian Carpathians its populations were found only at the East Beskids. Th e problem of conservation of T. shuttleworthii localities is related to restoration of the hydrological regime of landscapes and protection of river basin water resources. Key words: Typha shuttleworthii, area, distribution, ecology, communities, threats.
