TWS's position on livestock grazing
-important land use and management tool that can be used to alter rangeland vegetation toward specific objectives
according to TWS, livestock grazing must include:
-based on scientific studies and considers all resources, trends, interactions, and human values and needs
-provides for adaptive management and continued improvement of programs based on increased understanding and knowledge
-includes details for monitoring
-coordiantion among agencies and public
livestock grazing has three major effects on ecosystems:
-alteration of species composition
-disruption of ecosystem function
-alteration of ecosystem structure
three general recommendations for managing forest riparian zones
-logging prohibited
-construction of landings, campgrounds, roads prohibited
-control uplands to reduce sedimentation
