An area of 1,93,162 ha was selected in Pindgheb for qualitative and quantitative estimation of environmentally sound rangeland vegetation. Two ecological zones established were based on climate and two types of physiographic soils. These two main ecological zones were further subdivided and delineated into protected (mapping units 1.1 and 2.1) and unprotected (mapping units 1.2 and 2.2) areas making four ecological units. Four plant communities extracted for each ecological unit were integrated with climate and two types of physiographic soils; and ffinally delineated into vegetation and land use map showing four range ecological units. Vegetation analysis in protected forest and unprotected open grazing areas showed considerable vegetation degradation and ecological destruction for low ground cover, density and frequency of major unprotected areas. Analysis of variance of quantitative forage production of dry matter between protected forest and unprotected open grazing areas of each ecological zone showed highly significant differences. Unprotected over grazed areas showed about 2.5-7.0 times decline in forage production. Unprotected over grazed areas have 147% and 638% developmetn potential in each ecological zone for carrying capacity in animal units per hectare per year, if protected from open grazing and improved be system of grazing mangement.
