Site description
The Byala river valley and neighbouring hills, situated in the eastern Rhodopi mountains in southern Bulgaria. The vegetation is rich, consisting of old broadleaved deciduous forests of Fagus, Quercus and Carpinus, and sclerophyllous scrub (pseudo-maquis) of Juniperus, Phyllirea, Paliurus and Fraxinus, with Salix trees along the riverbanks. There are also coniferous plantations and rocky outcrops. Land-uses include hunting, forestry, fishing, extensive stock-rearing and cultivation. There is a small abandoned marble quarry, but drilling for minerals and other geological investigations still go on.



Key biodiversity
The site is important for its assemblage of Mediterranean-restricted species, and is one of the most important breeding areas in Bulgaria for raptors (Aegypius monachus, Circaetus gallicus, Accipiter brevipes, Hieraaetus pennatus, Otus scops) and Lullula arborea. Significant proportion (³1%) of national population breeding at site: Ciconia nigra (3-4 pairs), Neophron percnopterus (2 pairs), Aquila pomarina (1-3 pairs), Dendrocopos medius (5-10 pairs).



Pressure/threats to key biodiversity
Some nesting bird species are disturbed by hunting. A BSPB project for the eastern Rhodopi mountains (of which this area is a part) is ongoing under the Bulgarian-Swiss Biodiversity Conservation Programme.
