Frequent burning promotes invasions of alien plants into a mesic African savanna [PDF]

, 2010
Fire is both inevitable and necessary for maintaining the structure and functioning of mesic savannas. Without disturbances such as fire and herbivory, tree cover can increase at the expense of grass cover and over time dominate mesic savannas ...
