ASPECTE ÎN CONSERVAREA BIODIVERSITĂȚII: STUDIU DE CAZ - REGIUNEA DE DEZVOLTARE NORD

Abstract

The study proposed the conservation of biodiversity analysis in the Northern Development Region of the Republic of Moldova, through state-protected natural areas and ecological ne tworks, with the identification of the natural heritage elements dependence on environmental factors (abiotic, biotic, anthropogenic). In the region, the geological structure, the outcrops of the Badenian-Sarmatian deposits, the specific relief, the narrow valleys in the form of gorges, in com bination with other environmental components (soil, climate, water) present favorable habitats for the development of various types of ecosystems (petrophyte, forest, grasslands, wetlands, etc.) and rare species. Areas vulnerable to nutrient and nitrate pollution have been identified, where maintenance or improvement of water status is an important factor for protected areas in the Emerald network and wetlands of international importance. Biodiversity conservation actions in the region should respond to several environmental problems, among which: the presence of limited protected natural areas, insufficient to ensure the biodiversity conservation; fragmenta tion of natural ecosystems and habitats; intensification of the environmental changes impact on the system of wetlands and their associated natural ecosystems; the presence of limited urban/ rural green spaces, insufficient to ensure the ecological norms in the field; the negative impact of agricultural activities, especially in ecotone areas, etc.
