Résumé
Investigates several questions relating to the impact of continuous sheep grazing on the farm, structure and botancial composition of chenopod shrublands. Examines the effect of domestic livestock on ecological variables in three arid chenopod shrubland paddocks of South Australian rangelands. There were four major aims of this thesis. They were as follows : From the data on vegetation and edaphic features should enable us to answer the following questions for chenopod shrubland management in arid and semi-arid regions of South Australia : * What is the pattern of perennial chenopod shrubland in response to grazing around water points in arid and semi-area of South Australia ? * Are there any distinguishable areas (zones) in paddock grazing system for chenopod shrubland of South Australia ? * Which plant and soil features are most important as indicators of distinguished zones ? * How can these indicators be articulated in rangeland assessment and what is the outcome of this study for management practices, especially for chenopod shrubland of arid and semi-arid areas

Mots clés : Shrubland ecology South Australia. - Chenopodiaceae South Australia - Grazing Environmental aspects South Australia. - Erosion South Australia.
