Abstract
The Perșani Mountains, which are part of the Curvature Carpathians, separate the Transylvanian Plateau from the Bârsa Depression, border on the east, north and west with the Olt River, have a maximum height of 1292 m on Măgura Codlei and an area of approx. 1kmp. The permanent grasslands are quite well represented, starting with the hayfields from Lunca Oltului, up to the grasslands from the oak and beech floors, at higher altitudes. For grasslands harvested in hay, belonging to the phytosociological associations Arrhenaterum elatioris, Festucetum pratensis and Typhoidetum arundinaceae, a production of over 20 t / ha of green mass was evaluated and those degraded as Molinietum coerulae and Deschampsietum caespitosae only, 1 – 3 t / ha green mass with fodder value. The pastoral value of the hayfields is 4 – 20 for the degraded ones and 65 – 90 for the best managed ones. On the grasslands used for grazing with animals, the highest productivity is estimated at the associations Lolio-Potentilletum anserinae, Festucetum rubrae submontanum and Agrostetum capillaris, of 11 – 16 t / ha forage green mass and 63 – 74 pastoral value. The grasslands with the lowest productivity are from the associations Botriochloetum ischaemi and Festuco-Nardetum strictae submontanum with 1 – 3 t / ha forage green mass and 11 – 22 pastoral value. On average, on the grasslands in these mountains, in an optimal grazing season of 165 days, 0.73 livestock units (LSU/ha) can be maintained.
