  • Membership is a great resume builder

Since its creation at the turn of the 20th century, Xi Sigma Pi has become one of the most well-known natural resources and forestry honors societies today. Xi Sigma Pi was originally founded at the University of Washington on November 24, 1908, and is now comprised of over 40 chapters across the USA and Canada. In addition, Xi Sigma Pi has recently been recognized as a member of the Association of College Honors Societies.

The Omicron Chapter at Colorado State University was established in 1943. While Xi Sigma Pi was initially intended to be solely a forestry honors society here at Colorado State University, we have expanded our chapter to acknowledge the hard work and dedication put forth by students of ALL natural resources fields. Our membership represents the vast diversity of individuals present within the Warner College of Natural Resources at Colorado State University.

We meet biweekly in Forestry 127

Students must receive a
nomination letter to be a member
