Xi sigma pi is the oldest forestry honor society in the United States. Its purpose is to provide recognition of outstanding forestry students and faculty in order to help promote excellence in the profession of forestry. The Alpha Gamma Chapter is in its 12th year at Iowa State University. Since its inception at Iowa State the Alpha Gamma Chapter has maintained its tradition of being an academic/service honorary rather than a purely academic honorary society.
