STATE OF PLANT SPECIES WITH PROTECTION POTENTIAL OF FOREST ECOSYSTEM “RACOVÄJII DE SUD” Regina FASOLA Institute of Ecology and Geography, Academy of Sciences of Moldova, str. Academiei no. 1, 2028-MD Chisinau Abstract: The work presents the results of the flora assessment within the ecosystem “Racovätii de Sud”, that shows the presence of species with limited distribution within Moldova, which are protected nationally and internationally. Some of them are registered for the first time within studied ecosystem. Keywords: protection potential, rare plant species, forest ecosystem. Introduction The biodiversity evolved significantly throughout time along with changes and need to adapt to new living conditions. However, some species have gained a widespread within Terra others have disappeared or have remained in smaller territories. This phenomenon manifests itself in Moldova by destroying natural habitats, natural resources exploitation, and the indirect influence of pollutants, which results in diminution of abundance of flora and fauna species. The need to take urgent measures to conserve and restore habitats and ecosystems, protecting rare and endangered species is stipulated in international treaties, which are based on international agreements and conventions. Materials and methods As subject for study served the forest ecosystem “Racovätii de Sud” from the forestry Soroca, Soroca State Forestry Enterprise in the Ceresnovät River basin (Fig. 1). To achieve the aim of this study were conducted field and laboratory research in the period 2011-2015. Research in the field consisted of: the study of natural ecosystems in the main phenological phases of development of the ephemerals, annual, and perennial vegetation, inventory of rare species, evaluation of the abundance and state of valuable species [5].
