Grazing management processes and strategies for Riparian Wetland areas

Introduction In arid rangelands,cattle often focus grazing near riparian areas.Excess intensity or duration of grazing generally leaves inadequate riparian vegetation to stabilize stream banks against the cutting action of flowing water.Woody plants may lose diverse age structure needed for maintaining channel form or fish habitat.An excessively eroding channel may incise or entrench forming a gully that accelerates erosion.An incised stream does not access (flood) its floodplain so flood waters can not recharge an aquifer.Water rushes downstream in the wet season or during storm events,increasing downstream impacts rather than soaking into upstream floodplain soil and aquifers where it could have supported vegetation,dry-season flows,forage,and habitat.
