Mob grazing, a method that uses high stocking densities in small paddocks for short periods, was compared to rotational grazing and non-grazing systems in a study in South Dakota. The goal was to see how well each method utilized forage and affected the size of western snowberry patches. The researchers found that mob-grazing resulted in high forage utilization (42-90%) and reduced western snowberry patch volumes by at least 45%. In contrast, rotational grazing retained about half of the available forage and did not significantly impact the snowberry patches. The size of the snowberry patches before grazing influenced the impact of mob-grazing, with larger patches being browsed or trampled more than smaller ones.
