Abstract: The work contains the results from the investigation of habitats and flora in protected sites „Preobrazhenski Monastery” and „Derventa”, Veliko Tarnovo, Northern Bulgaria. Four phytocoenological relevés were made in represented stands of the forest vegetation. Habitats were determined according to EUNIS habitat classification and mapped. Totally 102 species of 81 genera, belonging to 44 families were established in the flora of the two protected sites. More than one fifth of the flora consists of Euro-Mediterranean elements including the Euro-subMediterranean. The larger part of the area of the two protected sites is covered by habitat G1.7C41 Silver lime forest (91Z0 in Natura 2000). These forests are an element of intrazonal relic forest vegetation. Forests of Acer spp. and Tilia platyphyllos distributed on steeper and eroded slopes are affiliated to habitat G1.A46 Southeastern European ravine forests (9180 in Natura 2000). The anthropogenic structures are affiliated to J2.2 Rural public buildings and J4.2 Road networks. On the basis of the obtained results some conclusions and recommendations for the conservation and management of the two protected territories are proposed.
