Artykuł przedstawia charakterystykę jednego z najliczniejszych stanowisk wyblinu jednolistnego Malaxis monophyllos (L.) Sw. w północno-wschodniej Polsce, zlokalizowanego w południowej części doliny Rospudy. Pędy rośliny skupione są na powierzchni około 30 m2, na mineralnym wyniesieniu, w otoczeniu rozległych, otwartych torfowisk. W 2008 roku na stanowisku tym pojawiło się 119 pędów, z czego ponad 1/3 kwitła. W kolejnym roku obserwacji liczebność pędów zmniejszyła się o 26%. W 2009 roku odnalezione zostały również kolejne trzy stanowiska, w odległości około kilometra od wcześniejszego. W związku z dużymi wahaniami liczebności pędów wyblinu jednolistnego wskazane jest objęcie opisanych stanowisk monitoringiem, który pozwoli na oszacowanie wpływu zmian siedliskowych, w tym postępującego zacienienia, na ich liczebność i potencjał reprodukcyjny

Malaxis monophyllos is a strictly protected species in Poland and in all European countries where it grows. It belongs to Amphi-Boreal-Alpine distribution group, with characteristic lowland-highland disjunction of populations. In Southern Poland it occurs in Carpathians and Sudety Mts and also in the Lublin and Małopolska Uplands. But most localities of M. monophyllos are in northern lowlands, especially in the Masurian, Pomeranian and Lithuanian Lake Districts, which are a part of boreal distribution range of this species. Populations are often very small and spatial isolated in moistly forests, swamps and peat bogs. The main reason of this situation is very fast declining number of populations of this species in many European countries over last years. In 2006–2009 new localities of M. monophyllos was discovered in the southern part of the Rospuda river valley in east part of Augustów Primeval Forest. The largest station consisted of 119 shoots, in which 33% were flowering in 2008. About 26% of shoots did not emerge in subsequent year. Another three localities were found, about 1 km from previous ones. Continuous monitoring will be a suitable action, to estimate impact of shade and environmental changes on generative reproduction and persistent of this localities

Malaxis monophyllos is a rare orchid with a fragmented boreal-montane distribution in Europe where it is associated with both natural swampy and anthropogenic habitats. We employed extensive sampling of M. monophyllos populations from different habitat types, over its whole European geographic range, to examine its genetic diversity patterns and phylogeographic structure using amplified fragment length polymorphisms (AFLPs). Our results revealed the relatively low genetic diversity of M. monophyllos, with the effect of small population sizes and inbreeding as the driving forces operating within the European part of its range. The statistically highest values of genetic diversity were found in populations from the boreal region (average: percentage of polymorphic loci PPL3 = 21.6%, Nei's gene diversity Hj3 = 0.144, the rarity index DW3 = 1.34), while populations from mountainous regions were characterised by a reduced level of genetic diversity (e.g. an average for Alpine populations: PPL3 = 18.1%, Hj3 = 0.121, DW3 = 0.84) in comparison to boreal ones. Our results revealed that the newly established anthropogenic populations in the Polish uplands were probably founded from numerous external sources and should be considered a significant source of the species' genetic diversity. We also confirmed the low genetic differentiation among M. monophyllos populations (FST = 0.074), with the lack of distinguishable genetic clusters, that supports results about the multidirectional gene flow between M. monophyllos populations in Europe, and directed conservation efforts on conserving all suitable for this species habitats.
