In the southern part, the average temperature is higher (approximately 14°5), the reduced cold months (1 month lower than 0°) and the hot summers (5 months higher than 22°), precipitations are equivalent. The grounds are particularly rich (brown grounds on Lœss). Very attacked by the human clearings it susbsist in the form of galleries along the rivers and interfluve.
