Grazing management of rangeland systems has not been well researched in Pakistan; grazing system the most sustainable is not known. In order to evaluate various grazing systems, a study was performed at Pabbi Hills Reserve Forest, Kharian, Punjab. Four simulated grazing treatments, viz. ungrazed control, continuous grazing, seasonal deferred grazing, and rotational deferred grazing, were tested in a randomized complete block design with four replicates. Response variables included species composition, fresh herbage yield, dry herbage yield of grasses and forbs, basal cover, and ground cover. Of the three grazing systems, the six-month seasonal deferred grazing system resulted in a marked increase in basal cover, but had no changes in relative species composition. A significant increase in grass cover and herbage production were also observed in this grazing system, suggesting that the 6-mo seasonal deferred grazing system is the most sustainable rangeland system.

Mari Reserve Forest of Pothwar tract covers an area of 3055 ha. Due to uncontrolled grazing, the range area has degraded and supports mainly unpalatable vegetation. In 2005-06, a 911 ha area was reseeded with Cenchrus ciliaris (Dhaman/Buffel grass). Forage production on both the reseeded/treated and untreated areas was measured in 2007 at the end of the growing season during October. The reseeded area produced about 16 times (7733 kg/ha) more forage than the untreated area (491 kg/ha). General Grass coverage on an average was 27% and 78% in untreated and treated pastures, respectively. Carrying capacity (Animal Units per Year) based on dry biomass of grasses/herbs was found to be 0.07 AUY/ha and 1.18 AUY/ha in untreated and treated areas, respectively or in other words, rakh with an area of 3055 ha can provide fodder to 3605 AUY if seeded, and otherwise it will support only 214 AUY. These results indicate that reseeding may be an important management practice for improving degraded rangelands of Pakistan.

A survey was conducted to assess the prospects of rangeland development in Thal tract of Punjab, Pakistan. At local level 64 respondents comprising 16 each of large, medium, small landholders and landless respondents were interviewed. Range personnel working in the tract were also interviewed. The number of livestock kept by respondents was highly correlated with the size of landholdings. Major source of income was livestock rearing. For grazing purpose, the dependence of respondents on vegetation of govt. rakhs varied from 94 to 100 percent. More than 41 percent forage requirements of livestock of all respondents remain unmet after grazing. Majority of graziers were facing problems like low carrying capacity of rakhs, lack of drinking water and protection measure forced by the Forest Department. The major constraints in range development efforts were lack of funds, and disinterest of range personnel working in the field. Other constraints were half hearted implementation of existing range management regulation and inadequate research.
