"Ecology and Management of the Colorado River and Grand Canyon" to be Topic of Presentation

"Ecology and Management of the Colorado River and Grand Canyon" is the topic of a presentation at 7:30 p.m. Wednesday, March 10, by noted ecologist Larry Stevens.

The talk, which is free and open to the public, will take place in McConnell Hall, Room 103.

Stevens, an avid natural historian and river runner, has spent the past 25 years engaged in ecological research on the rivers in the American southwest and the vegetation that grows along their banks. His studies have focused on native and non-native vegetation dynamics, with particular focus on the Colorado River ecosystem.

Stevens served as a National Park Service ecologist from 1988 to 1994, coordinating and conducting studies of the effects of Glen Canyon Dam on the Colorado River corridor in the Grand Canyon. Through affiliations with Northern Arizona University and Prescott College, he conducted and directed research contributing to the Glen Canyon Dam Environmental Impact Statement in 1995, the second largest environmental impact statement in the nation's history.

Stevens is presently a consulting ecologist for the Bureau of Reclamation's Grand Canyon Monitoring and Research Center.
