In this study authors estimated the rate of live herbage accumulation based on residual herbage remaining immediately after grazing in a short-duration (1-2 days) system, over the growing season. The rate of regrowth significantly declined as the season progressed, becoming insignificant or very limited in August. Residual herbage levels (i.e. grazing intensity) were significantly related to regrowth rate only at one of the two replicate sites (weather conditions could not explain the difference between sites). Despite a good fit to a curve-linear regression model (74-81% of variation accounted for), defoliation intensity across season could not explain all complex interactions in regrowth and recovery of tallgrass prairie in south-central Oklahoma.
