Na požárech National Nature Monument

The Na Požárech NNM is one of the most important small-size protected areas in the Český les Protected Landscape Area and the Bohemian Forest region. The protected area covers nearly 79 hectares and lies near the former village of Jedlina and very close to the former Iron Curtain on the German (Bavarian) border. These former meadows and pasturelands were used for agriculture until the mid-20th century but have now turned into peaty meadows.
 
These meadows previously supported a strong breeding population of black grouse (Tetrao tetrix) numbering 40 – 50 individual birds. However the opening of the Waldheim – Přední Zahájí border crossing and the following cold, rainy spring in 1995 led to the disappearance of this population. Even though the grouse no longer live here, the locality is still of exceptional zoological and botanical value. The rare cranberry fritillary butterfly (Boloria aquilonaris) can be found here – it is only found in the Šumava – Český les region in the Czech Republic. The value of this locality is also enhanced by the rare glacial relict spiders which can be found here (they have lived here ever since the Ice Ages). Rarer bird species include the whinchat (Saxicola rubetra), snipe (Gallinago gallinago) and occasionally the hen harrier (Circus cyaneus).
 
The vegetation on the Na Požárech NNM can be characterised as a complex of interspersed communities of peaty meadows, mat-grass meadows, reedbeds, transitional peatbogs, raised peatbogs and succession stages with colonization by opportunist tree species. A total of 252 vascular plant species have been recorded here, of which 25 are rare and specially protected. The bilberry willow (Salix myrtilloides) is a very rare find as it is only known from four localities in the Czech Republic. Other extremely valuable plants which grow on these meadows include the flea sedge (Carex pulicaris), slender sedge (Carex lasiocarpa), round-leaved sundew (Drosera rotundifolia), butterwort (Pinguicula vulgaris) and the creeping willow (Salix repens).
