Site description 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.
