Study of the Floristic Biodiversity Available on Permanent Pastures Located at Different Altitude Levels

The researches carried out between the altitude levels of 236 and 1300 m, in 13 localities from Banat Mountains, proved the influence exerted by stationary natural conditions on the botanic diversity of the vegetal cover. From one vegetal association to another, the total number of botanic species ranged between 9 and 21; the biggest number of species was recorded between 236 – 630 m altitude, and the smallest one between 462 – 650 m. The mean coverage degree of these species was 42.69% in the species belonging to the Poaceae Family (with a variation of 30-70%) and 12.85% in the species belonging to the Fabaceae Family (variation of 25-65%).
