ABSTRACT:-This study was conducted to determine the herbage production of five rangeland reserve in southern Jordan. Plant samples were taken for three years 1997, 1998, and 1999 from unprotected and protected rangeland areas. Higher differences in the amount of rainfall were excited between locations and seasons. Result showed that there are significant differences in fresh and dry weight of herbage between locations and years. Higher percentages of shrubs were observed compared with grasses and herbs during the drought years. Protected rangelands produced 4 times greater of dry weight of vegetation than those of unprotected area. Rehabilitation of degraded area can be achieved by management of controlled grazing.
