Site description A mountainous region located along the Czech-Polish border, covered mainly by Fagus and Picea/Fagus forests (500-900 m) and Picea forests (900-1,250 m). At higher elevations (1,250-1,450 m) there are Pinus mugo stands, glacial corries, peatbogs and subalpine meadows, with alpine habitats occurring above 1,450 m. Forestry is the most important economic activity. This area includes two areas that were treated as subsites in the previous international IBA inventory (Grimmett and Jones 1989): `Pancavska and Labska louka peatbogs' (former site CZ001-1) and Upska raselina peatbog' (former site CZ001-2).

Key Biodiversity The forest bird communities are the most important component of the avifauna. The IBA also supports populations of two species with limited distributions in the Czech Republic: Anthus spinoletta and Prunella collaris. A total of 153 breeding species were recorded during a 1991-1994 regional survey.
