Primula farinosa L. of Primulaceae family is a protected, rare and critically endangered species of Polish flora. All lowland sites of this species do not longer exist at present. The population number of the only one mountainous site discovered in 1959 in Beskid Sądecki (South Poland) is violently decreasing. The reasons for decrease in the population can be complex and associated with changes in both habitat changes and low effectiveness of propagation. In the course of the study, the population number was estimated and selected aspects of the biology of flowering of P. farinosa were assessed, phytosociological and habitat characteristics of the environment were prepared. The population amounted to 158 flowering specimens in 2011. Improper age structure of the population, characterized by a small share of juvenile plants indicates a possible regression of the population. The share of expansive species increased in the floristic composition of phytocoenosis as compared to historical sources. The assessed elements of generative propagation do not provide any grounds to suppose that the decrease of the population number is caused by disturbances in this field. High- and short-styled flowers are present in the population, a pollen is viable and new seeds are potentially able to germinate.
Themost beautiful Polish mofette occurs in the Sądecki (Sącz) Beskid, within the Krynica tectonic-facial zone of the Magura Unit (Inner Carpathians). It is located in the Złocki Stream upstream of the Złockie village in the Muszyna commune. The occurrence has numerous exhalations of CO2 in the valley floor and on the sides of this boggy stream as well as in the „Zatopione” and „Bulgotka” springs. It is also the site of the dry exhalation „Dychawka”. The floor of the valley is covered with gelatinous rusty-brown deposits of iron oxyhydroxides that precipitate either due to chemical or organic processes (the latter initiated by numerous microorganisms, mainly ferruginous bacteria). The site is legally protected as the Professor Henryk Świdziński monument of inanimate nature. In September 2005 it was made accessible for tourists and currently is an important geological attraction in the Popradzki Landscape Park.

Rozległe osuwisko, obejmujące cały zachodni stok Góry Parkowej, kształtowało się stopniowo w czasie trwania holocenu. Poszczególnym fazom jego tworzenia się odpowiadają skarpy nisz osuwiskowych, spłaszczenia, zagłębienia bezodpływowe i obrzeżające je koluwia, a także osady zawierające szczątki roślin i skorupki mięczaków. Datowania wykonane metodą radiowęgla oraz wyniki analizy malakologicznej pozwoliły na określenie wieku tych osadów i warunków ich depozycji. Cztery etapy rozwoju omawianego osuwiska, wyróżnione na podstawie szczegółowego zdjęcia geomorfologicznego, nawiązują do faz wzmożonej intensywności ruchów masowych w Polskich Karpatach. Przedstawiona została propozycja wyznaczenia ścieżki dydaktycznej, obejmującej 16 punktów obserwacyjnych

Large landslide ranging over the whole western slope of the Parkowa Góra Mt. has been gradually formed during the Holocene. Head scarps, flattened parts of the slope, shallow depressions and colluvial ridges as well as plant- and mollusc-bearing deposits correspond with particular episodes of sliding, distinguished according to detail geomorphological mapping. The age of these deposits and sedimentary conditions have been established according to result of both four radiocarbon dating and results of malacological analysis. Four stages of development of the mentioned landslide correlate with phases of increased mass movements, described in the Polish Carpathians. The didactic trail enclosing 16 sites should be traced along paths to demonstrate well developed forms of landslide morphology
