ANEVA, I., P. ZHELEV, L. EVSTATIEVA and D. DIMITROV, 2013. The ecological and floristic characteristics of populations of Sideritis scardica Griseb.in Slavyanka mountain. Bulg. J. Agric. Sci., Supplement 2, 19: 211–217
Sideritis scardica Griseb. is an endangered species with threatened and extremely vulnerable populations. The current study provides information about the population state and structure, vegetation dynamics and the place of the species in habitats in all locations of Slavyanka Mountain. Three localities of the species are investigated – at the base of the peaks Golyam Tsarev Vrah, Shabran and Gotsev Vrah. The studied populations of Sideritis scardica in all three localities are unstable and threatened. A list of diversity of vascular plants is made for each locality. The taxonomic structure of the flora and the ecological and biological characteristics are defined. Most of the dominant species (103) are long-lived, clonal perennials and only 9 species are annuals. The main geographical elements are those with Mediterranean origin or close to it.
