The Role of Cattle Grazing Management on Perennial Grass and Woody Vegetation Cover in Semiarid Rangelands: Insights From Two Case Studies in the Botswana Kalahari

On the Ground • We assessed the long-term effects of continuous and rotational grazing on grass and treedynamics on adjacent ranches in the semiarid Kalahari of western Botswana. • Rotationally grazed ranches had higher grass cover with more perennial grass species, higher grazing value (and capacity), and higher long-term stocking rates than their continuously grazed neighbors. Tree cover tended to be higher on continuously grazed ranches, suggesting that long-term continuous grazing reduced grass production and favored establishment of woody vegetation. • Improvement in semiarid rangeland health and production is unlikely to be achieved simply by reducing stocking rates; uniform grazing and growing season recovery periods are essential. • These and other case studies suggest that benefits of grazing strategies likely depend on scale and adaptive management. Future research should be at larger spatial and temporal scales.The Rangelands archives are made available by the Society for Range Management and the University of Arizona Libraries.
