The work presents characteristics of calciphile species from the dendroflora of Bulgaria (107 species), both facultative (77 species) and obligated (30 species) – their systematic structure according to families and genera, division according to biological types and live forms, as well as floristic geo-elements and spreading on vertical belts and floristic regions in Bulgaria. The conservation significance of calciphiles at national and international level has been shown on the basis of referent documents. A systematic list of calciphile species of the Bulgarian dendroflora has been presented.
