Fig. 3. Development of agistment networks in Australian rangelands. Large circles represent ecological subsystems; small circles, pastoral enterprises. (A) Open-range system with very large unfenced paddocks, uneven distribution of stock grazing pressure around watering points, and a high degree of natural drought-buffering capacity. (B) Fragmented system with more intense and evenly distributed grazing pressure and reduced natural drought-buffering capacity. (C) Fragmented system with agistment in which informal networks have developed to partially increase the scale of management.
