From Sept. 20–Oct. 13, 2007, the Upper Arb hosted "The Buckthorn Menace," an environmental art installation. During the course of the project, campus and community volunteers worked with artist Jim Proctor to clear the invasive plant species buckthorn from the installation site and render the plants into large-scale sculptures. The installation will stand for a full year to allow viewing over the four seasons. It will be dismantled in October 2008, and the project sites will then be restored as needed by planting indigenous trees and shrubs.To learn more visit the Buckthorn Menace web site.
