Species rich native grasslands are frequently converted to species poor exotic pastures; however, the consequences of these land use changes for ecosystem functioning remain unclear. Specifically, it is unclear whether: 1) intense livestock grazing will have similar effects in native and exotic ecosystems, and 2) pasture productivity can be increased by increasing species richness, by changing from native to exotic species, or simply by identifying the most productive species.
