Anthropogenic disturbance as a factor supporting the development of rare species as exemplified by Botrychium matricariifolium in the Silesia region of Poland : [poster]

Botrychium matricariifolium (Retz) A. Braun ex W.D. J. Koch (daisy-leaved moonwort; Ophioglossaceae), an endangered and strictly protected species ofmoonwort has lost significant number of its localitiesduring recent decades in Poland.
