Termites are an important structural pest in the United States and are capable of causing extensive damage to houses and other wooden structures. Costs for control, prevention, and repair of termite damage can reach $2 billion annually. However, termites play an important role in any ecosystem in which they are found. Understanding this role can facilitate controlling this structural pest. One such ecosystem is the Oklahoma Tall Grass Prairie Preserve. There have been no termite studies conducted on native tall grass prairies of Oklahoma, even though termites are abundant. The Oklahoma Tall Grass Prairie Preserve provides a unique opportunity to study the ecology of the eastern subterranean termite (Reticulitermes flavipes) in a non-disturbed natural habitat. Aspects being studied include foraging depth and changes in soil conditions over time, termite influence on plant growth and diversity, termite population density, and feeding preferences on available plant resources. These investigations will encompass at least two growing seasons.
