Abstract

The influence of sheep grazing on species composition and coverage by vegetation in arid and serniarid grasslands was observed along a gradient of sheep grazing intensities during one growing season in the Thar Desert, India. In both types of grassland, four plots were separated by fences and eight, six, three or zero sheep per ha introduced. Total coverage was higher and more stable under grazing pressure in the semiarid than in the arid grassland. The impact of grazing on vegetation coverage in the arid grasslands was remarkable. The large variation in coverage in the arid grassland was due to three dominant annual legumes, Indigofera species, which accounted for 93% of total variance in coverage. In the semiarid grassland, however, no dominant species was found and the changes in coverage caused by grazing were small.
