The article presents the preliminary results of research on changes in the abundance and population density of Epipactis helleborine carried out during the vegetation seasons of 2010 and 2011. The spatial distribution of ramets was analyzed in terms of population changes. The population studied was located in an anthropogenic habitat near the village of Guszczewina on the outskirts of the Białowieża Forest. The results of the study suggest that vegetative multiplication was dominant in the population. An attempt is made at finding the cause and extent of this phenomenon.
