As Iowa pastures continue to be dominated by cool-season grass species, strategic integration of a single mob-grazing event into pasture management offers a tool to simultaneously increase productivity of pastures and to improve grassland wildlife habitat through increased biodiversity. However, the success of the maneuver depends on climate, soil and landscape.

Key Question

Can strategic short-term use of mob grazing be used to enhance ecological services from pastures or ungrazed grass lands?


A single-mob grazing event significantly enhanced the botanical composition of either a pasture for grazing or ungrazed grassland for wildlife habitat. However, these responses were largely affected by soil moisture and land use history of the location as mob grazing was more effective at altering the botanical composition under high soil moisture levels on soils that did not have a history of cultivation.
