Summary:
Grazing by herbivorous mammals like bison increases biodiversity in North American grasslands, says National Science Foundation (NSF) ecologist Scott Collins, even during periods of frequent burning and other stresses. In fact, loss of species diversity in these grasslands due to frequent burning was reversed by bison grazing, according to Collins.

Grazing by herbivorous mammals like bison increases biodiversity in North American grasslands, says National Science Foundation (NSF) ecologist Scott Collins, even during periods of frequent burning and other stresses. In fact, loss of species diversity in these grasslands due to frequent burning was reversed by bison grazing, according to Collins. "Thus, reestablishing grazing in grasslands stressed by human activities enhances biodiversity," says the scientist. Collins' research results are published in this week's issue of the journal Science. His work was conducted at NSF's Konza Prairie Long-Term Ecological Research (LTER) site in northeastern Kansas, one of a network of 20 such NSF sites in North America and Antarctica.
