Climate and grazing interact to control rangeland vegetative characteristics at a regional scale on the Tibetan Plateau

Introduction Rangeland degradation on the Tibetan Plateau is often attributed to overgrazing.However,the effects of on-going climate changes,and their interactions with grazing,are rarely explored.In previous work,we demonstrated that experimental warming decreased plant diversity,plant aboveground production,and resulted in less palatable shrubs replacing more palatable graminoids ; these effects were dampened by grazing (Klein et al.,2004 & 2007).Here,we compared the shorter-term,site-scale experimental responses to the longer-term,regional-scale responses.
