Rotational grazing on rangelands: an assessment of the experimental evidence

摘要

Comparisons of continuous,season‐long grazing and rotational grazing have been conducted in numerous rangeland ecosystems world wide over the past 60 years.The preponderance of evidence generated from these experiments has consistently indicated that rotational grazing is not superior to continuous grazing on rangelands in terms of plant and animal production ( Heady 1961,Briske et al., 2008).However,rotational grazing continues to be promoted and implemented as a superior grazing system.The specific objectives of this synthesis were to summarize plant and animal production responses to rotational and continuous grazing and attempt to reconcile these contradictory perspectives.
