Fig. 2. Effect of grazing method on change in density of vaseygrass after 1 yr (1994; P = 0.033) and after 2 yr of grazing (1994–1995; P = 0.238). Continuous is simulated continuous stocking whereby steers grazed the 250-m2 pastures for 2 to 6 h two or three times per week to the target stubble height.

Fig. 3. Effect of grazing method on change in cover of vaseygrass, limpograss, and other plants (A) after 1 yr (1994; P = 0.025, 0.100, and 0.861, respectively) and (B) after 2 yr of grazing (1994–1995; P = 0.018, 0.071, and 0.844, respectively). Continuous is simulated continuous stocking whereby steers grazed the 250-m2 pastures for 2 to 6 h two or three times per week to the target stubble height.
