Grazing disturbance a benefit to species diversity in re‐established native grass stands

摘要：

In western Canada, increasingly land is being taken out of annual crop production and returned to perennial cover, in part due to an aging producer population but also the recognition of improved sustainability of perennial systems.A portion of the reseeded perennial cover has been native plant material.Seeding mixtures of species have included only a single species to over 100 species.Recommendations for utilization of seeded native grassland species have ranged from a year to establish prior to grazing to no grazing to be allowed.This series of studies set out to determine the possible benefits of seeding a simple seven species mixture versus a more complex fourteen species mixture and the impact that grazing might have on the resulting plant communities.
