We quantified three success criteria for 8–10-year-old grassland plantings in large-scale tallgrass prairie restoration (reconstruction) sites relative to three nearby prairie remnant sites. The restoration sites included management of native ungulates and fire, important regulators of diversity and patchiness in intact grasslands. These have not been incorporated simultaneously into previous studies of restoration success. We have shown that current restoration methods are unable to restore plant diversity in tallgrass prairie. Grassland restoration will be improved if the number of species that co-exist can be increased. New, local- scale restoration techniques are needed to replicate the high levels of diversity observed in tallgrass prairie remnant sites.
