With an area of 18 hectares, the Upolínová louka (Globeflower Meadow) National Nature Monument represents a complex of waterlogged meadow communities typical for the Slavkovský les (Slavkov Forest), which are home to rare plant species. Along with the Křížky NNM, the Upolínová louka NNM has been included in the network of Sites of European Community Significance. The international significance of the site is mainly based on the presence of serpentine-dependant endemic species. Its national significance is evidenced by the presence of several critically endangered and highly endangered wild flora species. At an elevation of 800 metres, we may find orchis species (orchids) – i.e. the western-marsh orchid (Dactylorhiza majalis), common spotted orchid (Dactylorhiza fuchsii) or the coralroot orchid (Corallorhiza trifida). Furthermore, it is one of the two habitats of the protected swamp willow (Salix myrtilloides) as well as marsh lousewort (Pedicularis palustris) the carnivorous common butterworts (Pinguicula vulgaris), Siberian iris (Iris sibirica), bogbean (Menyanthes trifoliata) and especially globeflower (Trollius altissimus) which forms vast yellow carpets when in blossom. Frequently encountered animal species include the common European adder (Vipera berus), smooth snake (Coronella austriaca), slow work (Anguis fragilis), sand lizard (Lacerta agilis) and alpine newt (Triturus alpestris). The site was an important lek of the black grouse (Tetrao tetrix), the remaining scarce population of which still inhabits the area. The site also used to be the nesting area of the black stork (Ciconia nigra) and the black woodpecker (Dryocopus martius). Among meadow fauna, we may find the corncrake (Crex crex) common quail (Coturnix coturnix) and the extremely endangered butterfly of the flowery peat bogs, i.e. the moorland clouded yellow butterfly (Colias palaeno).
The Upolínová louka NNM is located on the other side of the road in the vicinity of the Three Crosses.
