Ecoareal of Spiranthes spiralis within Europe: a synphytoindication aseessment

Abstract

There is given an overview of ecological areal of Spiranthes spiralis within Ukraine and Europe. The analysis is performed with the use of synphytoindication assessment of phytosociological relevees from ten European countries and covers 12 ecological factors (both edaphic and climatic). The narrowest amplitudes have factors of soil salt regime and continentality but there is no evidence of any strong ecological limits for the species’ spread within Europe. Keywords: Spiranthes spiralis, econishe, ecoareal, Europe, Ukraine, synphytoindication.
