A 16 hectare exclosure was established in Ziarart Juniper forests in 1949 to find out the effects of protection on the vegetation and soil characteristics. In 1977, twenty seven years after its establishment, eighty randomly selected one square meter plots were studied for forage production, frequency and surface features inside the exclosure and equal number outside. Trees cover; forage yield and frequency of grasses, and frequency of more palatable shrubs was higher in the exclosure than in the open. All the species recorded in the grazed area were also found inside the exclosure, but with lower forage yield and frequency, while some new more palatable species got established inside the protected area.
