The Assessment of Grasslands Productivity of the Leaota Mountains and the Western Side of the Bucegi Mountains

The permanent grasslands of the Leaota Mountains and the western side of the BucegiMountains located at 700-2130 m altitude from a phytosociological point of view belong to theJuncetea trifidi, Nardo-Calunetea, Seslerietea albicantis and Molinio-Arrhenatheretea classes,with 4 orders, 7 alliances and 9 plant associations. Vegetation coverage was on average 76%and the number of cormophyte species in reliefs was 44, being quite high. The participation ofspecies with forage value in the 9 associations was 31%, quite low, with a poor pastoral value(17.8) and low production of green mass (1.7 t/ha). The most valuable association wasScorzonero rosae - Festucetum nigricantis with 41.2 (average) pastoral value and 7.52 t/ha(middle) green mass, Productions of 2-3 t/ha green mass are achieved in the associationsAsperulo capitatae- Seslerietum rigidae and Seslerio haynaldianae-Caricetum sempervirentis,in the remaining 6 associations it was evaluated below one ton per hectare. Finally, at thephytosociological level, an average of 1020 liters of milk/ha was evaluated in 95 days ofgrazing season with variations from 200 l/ha at Molinietalia to 2040 l/ha at Seslerietaliaalbicantis. The productivity of the grasslands in the study area is very low due to thedegradation of the grassy carpet.
