Abstract

Grazing distribution and grass utilization was evaluated in intensively managed fields in the southern Aspen Parkland near Kirriemuir, Alberta. Three fields, 130 ha in size(with dimensions .4 x 3.2 km) were grazed by 1,000 cow/calf pairs for S days each. Stock water was accessible only from one end of each field. Grazing distribution was evaluated by monitoring grass utiliza- tion daily during grazing and after grazing at 0.1, 0.8, 1.6, 2.4, and 3.1 km from water. Final utilization did not differ within fields, escept for a decline at the maximum distance from water (3.1 km). Temporal utilization patterns existedand could best be described as a wave, with defoliation beginning near the water source on day 1 of grazing and proceeding outward from water until the ends of the fields were grazed on day 5. Final utilization was uniform; selective grazing of areas close to water was not removed by intensive management, but was masked by a rapid rate of defoliation.
