The serpentinite rock on the pastures in the vicinity of Prameny (Springs) is a nameless rock outcrop formed by serpentinite and it is visible northwards from the road which leads along the Three Crosses and Globeflower Meadow. The rock formation is located at an elevation of 790 metres and it rises approximately 7 metres above the surrounding terrain. A grooved and often rather swampy field road leads to the rock. It is best accessible by bike in slightly frosty weather, when there is still no snow and the meadow is frozen and you do not have to flounder in the mud. On the other hand, you will not see the rare plant species, which grow in the surroundings of the rock cliff only in the season. The most significant wild flora species include mouse-ear chickweed (Cerastium alsinifolium) and Sudeten bedstraw (Galium sudeticum). Mouse-ear chickweed may be found only in this locality and on neighbouring sites in the central part of the Slavkovský les PLA between Mnichov and Prameny. Sudeten bedstraw may also be found at several localities in the Krkonoše (Giant) Mountains. The characteristic biotope has been preserved in this area thanks to the serpentinite parent rock and to occasionally grazing goats or cows. Grazing is precisely what the rare plant species need in order to spread. The strictly protected and rare wild flora species are complemented by fern dependant on the serpentinite sub-grade rock, such as the ladder spleenwort (Asplenium adulterinum) and serpentine spleenwort (Asplenium cuneifolium). Animal species include the common European adder (Vipera berus), common lizard (Zootoca vivipara) or the corncrake (Crex crex).The area is significant on an international scale and it is a part of the most extensive serpentinite locality in the Czech Republic with unique non-forest serpentine flora. For the time being, however, it is not subject to protection by the state, but it is included in the list of localities proposed to be designated as protected areas.
