Effects of livestock grazing on wetlands: Literature review

Report: TR 2004/16
Author: PN Reeves, PD Champion, National Institute of Water and Atmospheric Research Ltd (NIWA)

Abstract

This report reviews the available scientific literature on the effects of livestock grazing in wetlands. It specifically identifies the effects of livestock grazing on the physical and biological components of estuarine, riverine and palustrine wetlands with the aim of providing preliminary guidelines for livestock grazing in these wetland types. Research gaps are then identified that could contribute to the development of more definitive wetland grazing guidelines.
