Polany stanowią bardzo ważny element środowiska przyrodniczego Gorców. Zaprzestanie na nich wypasu i wykaszania zapoczątkowało proces samorzutnych zmian krajobrazu w wyniku zarastania polan. W artykule opisano zmiany powierzchni górnoreglowych polan w latach 1954–2003, czyli w ciągu niemal 50 lat, kiedy te nieużytkowane już obszary stopniowo ulegały renaturalizacji.

The renaturalization process, being a result of the end of grazing and mowing, leads to a gradual disappearance of glades. The total area of analyzed glades in the Gorce Mts. was in 2003 by 125.69 ha less than in 1954 i.e. – 1/3 the original. Two small glades had become completely overgrown, other had become fragmented. The rate of forest expansion had not been the same an all the investigated glades. In the Gorce Mts most of the glades are private. For this reason any protective activities conducted by the Gorce National Park encounter hindrances. A decline in biodiversity and a decrease in the tourist attractiveness of the mountain landscape are the most important negative results of the glades overgrowing.
