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

Rare inland halophytic vegetation including the associations Salicornietum prostratae, Spergulario marginatae-Suaedetum prostratae, Puccinellietum limosae, com. Puccinellietum limosae - a variant of Aster tripolium subsp. pannonicus and Astero pannonici-Bolboschoenetum compacti have been found on 3 localities in the Drohobych region of western Ukraine. These are isolated (island') localities, almost unknown until today. Halophytes grew there on salted sites in the vicinity of the old salt industry. Species of halophytes previously not known from this region were discovered: Aster tripolium subsp. pannonicus, Bolboschoenus maritimus, Gypsophila paniculata, Limonium gmelinii, Lotus tenuis, Puccinellia distans, Sonchus palustris, Suaeda prostrata, Trifolium fragiferum var. bonannii, Triglochin maritima, Typha laxmannii and Zannichellia palustris subsp. pedicellata. The occurence of these plants strictly depends on the presence of salt in the soil and they are endangered by shrinkage of salted sites following the termination of the salt industry in Drohobych region.
