The site covers part of the Western Bieszczady range, the only part of the Eastern Carpathians lying within Poland. The lowest part of the site is mainly deforested, above which is subalpine forest (covering 84% of the site), dominated mainly by beech Fagus. Above that are extensive alpine meadows and Vaccinium heath, with alder Alnus shrubs.
A total of 161 species have been recorded. Species of global conservation concern that do not meet IBA criteria: Aquila clanga (1-2 non-breeding birds).
Pressure/threats to key biodiversity
The main threats are infrastructural and urban development along river valleys and within Landscape Parks (new hotels, pensions, etc.), drainage, loss of suitable habitat features for raptors and hole-nesters, and forest succession in open habitats. Almost the whole area is part of a transboundary Biosphere Reserve shared with Slovakia.
