Floristic analysis of Mt Slivenska (Eastern Stara Planina, Bulgaria)

Investigation of biological diversity is an important prerequisite for environment protection and is particularly topical in the context of the ongoing climate changes and altering public awareness of the strong connection between Man and Nature. The paper presents floristic diversity of Mt Slivenska. Presence of 1217 species has been identified, belonging to 458 genera, 95 families, five classes, and four divisions. Criteria for the elementary flora have been met. The great number of endemics, relicts and conservationally important taxa, and a comparative analysis with other similar regions, define the importance of the territory for theprotection of floristic diversity. For the achievement of this goal, it will be necessary to create a monitoring system in the protected territories and areas of the region.
