Technical Abstract: Biodiversity is a hot topic, but can understanding biodiversity help with pasture management? A diverse pasture may use resources more efficiently, extend the grazing season longer, resist weed invasion, and be more successful in stressful conditions. Animal production can be as good or better on a multispecies pasture as on a single-species pasture. Planting and rotational grazing can be planned to support diversity, allowing the grazier to take advantage of the many potential benefits.
