Abstract
In the European Union, natural habitat 62CO* Ponto-Sarmatian steppes is limited in its range and occurs only in two member states—Bulgaria and Romania. This grassland habitat was a subject to various impacts over the years and suffers on a decrease in its area, changes in species composition and occurance of invasive and ruderal species. The most significant threats to the habitat are related to intensive or excessive grazing of livestock, abandonment of grassland management (e.g., cessation of grazing or mowing), afforestation, plowing, conversion into agricultural land, conversion to other land uses (tourism, recreation, urbanization, construction of infrastructure), construction of energy plants and natural succession. In the present study we provide a comparative analysis of the actions aiming to protect the priority natural habitat 62CO* Ponto-Sarmatian steppes on the territory of EU. In addition, we investigated and compared the species composition of defined sites from 62CO* in Romania and Bulgaria to obtain up to date information and to confirm the current presence of the habitat. We discuss on the necessary measures for effective management of this protected habitat, as well as on the needed efforts to achieve favourable conservation status.
