Abstract

The permanent grasslands from the analysed area are located in the central part of the Orăștiei Corridor and the west of the Șureanu Mountains, from 225 -1,630 m altitude. The coverage with grassy vegetation is 91% and the average number of vascular plants on the vegetal associations is 60. The participation in the grassy carpet of fodder species reaches almost 60% and the harmful ones over 30%. The average pastoral value (PV) is 45 with differences from 60 - 80 for the most valuable associations to 5 - 7 for the degraded ones. The highest green mass production (GMP) of the grasslands was estimated at over 23 t/ha at As. Arrhenatherum elatioris harvested as hay and As. Trifolio repenti - Lolietum with 19 t/ha that has a grazing capacity of 1.6 UVM / ha in a season of 185 days. The worst results are obtained in the economically degraded associations Violo declinatae - Nardetum, Junco - Molinietum, Botriochloetum ischaemi and Clinopodio - Pteridietum aquilini, with 5 -7 PV and 0.4 - 0.8 t/ha GMP
