RESEARCHES REGARDING THE EVOLUTION OF THE VEGETATION ON OCCASIONALLY USED GRASSLANDS FROM SURDUCULUI HILLS PUBLISHED

Ioana Loredana Tomodan, Alexandru Moisuc, Carmen Durău
The purpose of this work is to determinate the evolution of the vegetation from occasionally used grasslands from Surducului Hills. The study represents a continuation of the previous researches having in view to set how setting a fluctuation or succession of the vegetation is, following a disturbance of the dynamic balance of the grassland due to some internal or external factors. The results obtained indicate that these grasslands are in an intermediary succession stage, the coverage degree of the valuable species from forager point of view (grasses and legumes) being in decrease during 2008-2009 in comparison with 2002. I change, on all four studied grasslands is noticed an increase of the coverage percent of the species from other botanical families, species from other botanical families more or less valuable as forage.
