Conservation Significant Plant Taxa in the Eastern Sredna Gora Mountain Floristic Subregion, Bulgaria

摘要

The urbanization of environment is a global phenomenon, concerning all levels of Nature ecosystems’ organization, and leading to the reduction of the variety of organisms, and the loss of habitats. This fact increases the significance of every investigation, connected with floristic composition and biologic diversity in anthropogenically loaded territories. But in the cities and suburban areas a positive correlation is often reported between the degree of urbanization of the environment and species diversity, due to the wealth of man-made habitats. The current study analyses the conservation significance of the Eastern Sredna Gora Mountain floristic subregion. The low altitude and favorable geographical location make the region extremely overloaded from anthropogenic point of view. Despite this, 30 species with Nature conservation status, according to the Bulgarian and international legislation are registered as a result of the examination, 3 species are confirmed for the Sredna Gora Mountain floristic region, 27 species are pointed in the Eastern Sredna Gora Mountain floristic subregion for the first time.
