Abstract:
The present study is the result of investigations performed in the
proximity of the Lower Prut Natural Park. The causes and the consequences
of the anthropic impact, in the last 50-60 years, from the Lower Prut
hydrographic basin are given especially by: the disturbances of hydrological
conditions of the Prut River (after the building of the Stanca-Costesti
accumulation dam, which stopped yearly flooding , the water supply in pools
and the lakes being insufficient; the lack of seasonal floods led to excessive
soil salinization); draining up of some sown areas of wet lands (easily
flooded lands); poaching, hunting; the diminution of meadow forest areas;
intensive grazing, the protected area perimeters included etc.
The extension of agricultural surfaces by means of ploughing has
destroyed the fallow lands and the natural meadows of the Lower Prut area,
very rich in numerous species of flora and fauna. The massive deforestation
of the previous century, interested in changing former forest areas into
agricultural zones has led to important changes to the climate, plant
complexity and soil characteristics.
Important changes occurred: steppe characteristics prevailed, so that
the climate was no longer wet and cool, but drier and warmer, the lands
losing part of their vegetation
