Researches on environment degradation in the natural sites on Moldova river lower course

Abstract

The European Ecological Network Natura 2000 in Romania is present on the lower course of the Moldavian River through the "ROSC10364 Community Site of Rila Moldova between Tupilati and Roman". Research over 15 yearshas shown that part of the natural reserve is affected by degradation phenomena. In the researched river sector (the minor and major riverbed, the riparian area) are located ballasts, bridges, water catchments, constructions, agricultural holdings, trees and bushes areas, etc. All these have influenced the arrangement of the river bed and the riparian area, which led to the degradation of the river and riparian habitat. Natural and anthropic risk factors have contributed to the degradation of the environment in the researched river area. The most important influences were the floods of the last 15 years, the exploitation of the ballast, the shore circulation areas, the absence of maintenance works in the river bed, etc.
