Fire affects mesic grasslands differently in North America and South Africa. Species richness increases with high fire frequency in South Africa, but increases with low fire frequency in North America. Nutrient addition reduces species richness in a similar manner on both continents. Species traits, including height and methods of clonal reproduction are likely to contribute to the differing responses.
