Balochistan can be divided into two zones regarding precipitation and grazing quality of the rangelands. The northern zone comprises the best ranges of the province located in the districts of Zhob, Loralai, Sibi, Nasirababd, Kohlu, Pishin, Quetta, Kalat, and the northern 18% of Khuzdar area. This zone, equivalent to only 38% of the total province area, carried 76.5% of the provincial livestock. The southern zone comprises the poorest ranges located in the rest of Khuzdar, Chagai, Khanar, Panjgur, Turbat, Gwadar and Lasbela district, which covers 62% of the province and carries only 23.5% of the livestock population (FAO, 1983). The high stocking rate and lack of grazing management in the Northern zone is rapidly depleting these ranges. Geomorphologically, the rangelands in Balochistan can be distributed into six types of landscapes, including mountains, uplands, piedmont, desert, flood plains and coastal plains. Muhammad (1989) divided rangelands of Balochistan into three main categories: Central Balochistan ranges, Western Balochistan Ranges, Eastern Balochistan Ranges. The biomass productivity varies from 30 to 380 kg/ha (Fig. 2.).

5% sedentary (FAO, 1983). Nomadic flocks move continuously in search of forage. They have no agricultural land and migrate from uplands to lowlands in winter and come back again in spring to uplands. In lowlands they purchase generally sorghum crop for animal grazing. The size of a nomadic flock may vary from 200 to 700 sheep and goats. Transhumant flock owners have agricultural land and dryland agricultural activities. In winter some of them also migrate along with the families to lowlands. Sedentary flock owner raise few animals (5-20) on orchards, crop stubbles and also stale feeding. However, these systems are under transformation due to many factors like increase in livestock and human population, water mining for agriculture and orchards, changes in traditional migratory routes due to Afghan war. In a recent study, two new nomads groups (Commercial nomads and Nomad Transhumant) have been identified in Balochistan (MINFAL, 2000).
