Flora of xerothermic sites of the Zachodniowołyńska Dolina Bugu Special area of conservation (Eastern Poland): The influence of habitat on rare grassland species

Abstract

The aim of the investigation was to study the flora of grasslands within the Zachodniowo?y?ska Dolina Bugu Special Area of Conservation and to identify the types of habitats with the highest concentration of grassland species. In the years 2011-2012, floristic analyses covered the slopes of the valley of the Bug river, balks and places of shallow bedrock deposition, roadsides, as well as railway and earthwork sites. One hundred and fifty eight plant species belonging to 37 families were found. Though considered extinct in Polish flora, Dianthus collinus subsp. glabriusculus was discovered. Close to half of the recorded species (47%) were grassland taxa and 15% rare and/or protected plants, which make the studied area particularly valuable for the conservation of biodiversity. The fewest grassland plants occurred on habitats that are under the influence of agriculture, where the dominance of nitrophilous and herbicide resistant plant species was observed.

High occurrence of rare inland halophytes on post‐mining sites in western Ukraine

“…It is possible that they have been brought with a railway transport or are the remains of an old salt pasture crossed by the railway line. Beyond its closed range, the sites of Gypsophila paniculata are frequently of synanthropic origin (Woch and Hawryluk ).…”

“…Ponadto charakterystykę zbiorowisk kserotermicznych występujących na stromych zboczach doliny Bugu zawarto w kilku publikacjach (Wójciak, Urban 2011;Woch, Hawryluk 2014). Podsumowanie badań florystycznych prowadzonych w latach 2002-2012 w dolinie Bugu (odcinek Gołębie-Kostomłoty) przedstawiły Urban i Wójciak (2012).…”
