Pulsatilla patens has a circumpolar distribution from Eurasia to North America. This species occurs in the central and central-eastern parts of Europe, where is a rare and threatened species. In Poland, the largest number of sites is found in the north-east. A study on populations of P. patens was carried out in 2009–2010, at two wildlife refuges of the NATURA 2000 (N2000) network situated in North-Eastern Poland. Local names are following: the “Sejneńskie Lake District” (SLD) and the “Grasslands in the Military Training Grounds in Orzysz” (GMO). The current population structure of P. patens was estimated including the number, density and structure of different life cycle stages. Seventy-nine research plots of 2 m × 2 m were established at sites: dry heath, xeric sand calcareous grassland and pine forest. In each plot, all individuals were recorded and classified into life cycle stages: juvenile, vegetative and flowering individuals. The studies were carried out twice a year – in spring, during the full bloom of Easter pasque flower and in summer, in time of its fructification. The bioindication method was applied in order to determine the climatic and soil conditions of the habitats. Relationships were estimated between these population characteristics and habitat-related features such as the cover of phanerogams, cryptogams, litter, and bare soil. The population found on the GMO, was composed of 316 individuals which gives the density 6.4 ind. per plot while the one in SLD consisted of 202 individuals which gives the density 6.7 ind. per plot. The age structure of the populations proved that these were stable populations. This was evidenced by a large share of vegetative individuals – in both populations they prevailed (ca 64%). The highest share of juvenile individuals was noticed at the sites characterized by a moderate cover of cryptogams (21–35%). The analysis of correlations showed that on the non-forest habitats – dry heath and xeric sand calcareous grassland, the total number of individuals and number of vegetative individuals were negatively correlated with the cover of phanerogams and the cover of cryptogams. It was recorded negative impact of dense moss layer on the number of juvenile individuals. Moreover, the cover of litter had negative influence on the total number of individuals, number of juvenile and vegetative individuals. In contrast, the total number of individuals and number of juvenile individuals at that sites was positively affected by the cover of bare soil. A positive correlation was found between the number of vegetative individuals and phanerogams, and also between the number of juvenile individuals and the cover of bare soil at forest habitats. Negative impact on total number of individuals and the number of flowering individuals is exerted by the cover of cryptogams. Considering the ecological indicators set for the plant communities in which Pulsatilla patens appeared, it should be concluded that these were the habitats characterized by moderate light and moderately warm climate condition. Thecommunities with Pulsatilla patens grew on dry and fresh soils, oligotrophic and mesotrophic ones, composed of sand and argillaceous clay. The pH ranging was from moderately acidic to neutral. The analysis of the age structure of the examined populations, the latter can be said to be stable. It can therefore be assumed that the Eastern pasque flower has met the favorable habitat conditions at the analyzed sites, therefore it is justifiable to claim that these sites will exist in the future and will constitute an important part of the resources of this species in Poland.

This paper presents a study on a population of Pulsatilla patens conducted in 2012 in the Myszyniec Forest District in Natura 2000 area ‘Myszynieckie Bory Sasankowe’ in the Kurpie forest (NE Poland). The purpose of the study was to determine the population structure of Pulsatilla patens, especially with regard to abundance, density, and percentage of generative plants in the total population. Correlations were examined between these population features and selected environmental characteristics including ecological indicator values, community layer coverage, number of species group. For the evaluation of the linear relationship between the variables, Spearman's correlation coefficient was used. The research confirmed a significant effect of light availability, clear cuttings areas on all mean values of such indicators of plants as number of flowers, number of plants, share of vegetative and generative plants.

Celem pracy było zaproponowanie sposobu inwentaryzacji rzadkich gatunków flory na przykładzie gatunku sasanka otwarta Pulsatilla patens na terenach leśnych oraz określenie skuteczności poszukiwań w trakcie jednorazowej lustracji potencjalnych siedlisk tego gatunku. W tym celu określono na podstawie dostępnej literatury parametry drzewostanów odpowiadających występowaniu gatunku w lasach obrębu Krutyń w Nadleśnictwie Strzałowo oraz wykonano jednorazową lustrację wytypowanych powierzchni w terminie optymalnego rozwoju i kwitnienia osobników inwentaryzowanego gatunku. Zaproponowany sposób może stanowić podstawę dla prowadzenia poszukiwań siedlisk przyrodniczych tego gatunku w innych nadleśnictwach oraz innych rzadkich gatunków roślin chronionych w trakcie powszechnej inwentaryzacji siedlisk przyrodniczych przeprowadzanej obecnie w Lasach Państwowych.

The aim of the study was to propose the effective method of cataloguing rare species of flora like pasque flower Puslsatilla patens in the natural stations of this species. Moreover the aim was to determine the effectiveness of research during single survey of potential habitat of this species. On the basis of available literature, parameters of forests areas, which reflected the existence of the species in forest unit Krutyń in forest district Strzałowo were defined. As for a single survey it was carried out in particular area during the optimal time of development and florescence for speciman of the species. The proposed method might become a base for searching for natural habitats of this species in other forest districts. It might also be used with reference to other rare species of protected plants during general inventory of habitats, which is currently being carried out in national forests of Poland.

Pulsatilla patens to jeden z najrzadszych gatunków roślin naczyniowych na terenie Gór Świętokrzyskich, znanych tu na zaledwie kilku stanowiskach. W kwietniu 2007 roku znalezione zostało nowe stanowisko tego gatunku w Starachowicach na Przedgórzu Iłżeckim. Sasanka otwarta była tu notowana w lesie dębowym o charakterze świetlistej dąbrowy (Potentillo albae- -Quercetum).

Pulsatilla patens is rare and protected plant species in the territory of Poland. Its populations are usually very small and they are often composed of only a few specimens. New locality of Pulsatilla patens in Starachowice (Iłża Foreland) was found in April 2007. Only two specimens of this species grow in oak-forest (Potentillo albae-Quercetum), in forest section 24a, Wanacia forest district, Skarżysko-Kamienna Forest Inspectorate
