Site description (2000 baseline):
Site location and context
A rather low mountain in the south-easternmost part of the country, through which the Veleka and Resovska rivers flow. The mountain is covered by mature broadleaved forests and pastures. Natural forest of
Fagus predominates, although
Quercus is common in higher areas. Mediterranean grassland and shrubland are widespread. Alluvial forests occur mainly at the river-mouths and are dominated by
Fraxinus, with dense
Salix and
Alnus. Temporarily flooded areas along the rivers are overgrown with aquatic vegetation. Land-uses are forestry, hunting and extensive cultivation and stock-rearing.
This is one of the most important breeding areas in the country for
Ciconia nigra, for raptors such as
Neophron percnopterus,
Circaetus gallicus,
Aquila pomarina,
Aquila chrysaetos,
Hieraaetus pennatus and
Bubo bubo, and for forest species such as
Picus canus,
Dendrocopos medius and
Ficedula semitorquata. The mountain is also a major migratory bottleneck site, where more than 33,000
Ciconia ciconia pass overhead each autumn. Species of global conservation concern that do not meet IBA criteria:
Phalacrocorax pygmeus (common on passage),
Pelecanus crispus (common on passage),
Crex crex (occurs on passage).
Pressure/threats to key biodiversity
Intensive tourism along the Black Sea coast during the past seven years has led to destruction of alluvial forests. There are several projects for the construction of reservoirs on the Veleka river, possibly disturbing the water regime. People often destroy nests of raptors, their eggs and chicks when cutting trees. Uncontrolled hunting and fisheries, and unsustainable forest management, are also problems. The IBA is designated as a National Park, comprising five Strict Reserves with Buffer Zones, 12 Protected Landscapes and five Nature Monuments. The management plan for the National Park was prepared by the Ministry of Environment under the Bulgarian-Swiss Biodiversity Conservation Programme.
