Very different soil and climate conditions that determinates grassland formation and the powerful anthropic influences determinate a great variability from botanical composition point of view but also from forage yield and quality. Having in view the low level of the permanent grasslands yield there is needed the applying of a technical and organisational measures complex with the purpose of the improvement of nutritive quality and its rational use. Depending by these aspects the vegetation can be changed fundamentally concerning the improvement or depreciation of botanical composition in a very short time.
