Impact of grazing on vegetation of Artemisia— annuals rangelands in semi desert of Uzbekistan
Grazing pressure is the most important factor impinging plant community composition and biomass in natural grasslands.Excessive stocking is the main reason for rangeland degradation worldwide.The semi desert foothills region of Uzbekistan covers about 4 million hectares (Gaevskaya et al.1975).This region is the most densely populated area of the arid zone of Uzbekistan.Karakul sheep husbandry is the most important livestock production sector in this region.The objective of our study is to measure the impact of grazing on plant community composition and productivity of the dominating A rtemisia communities.The research focuses on the effects of grazing on plant productivity, floristic composition and the determination of stages of rangeland degradation as a result of overgrazing around settlements and wells.
