Join us in Ajo, Arizona!
March 7 - 10, 2016   --   REGISTER NOW!

Back by popular demand!  Participants in the March 2010, 2012, and 2014 tri-national symposia organized by representatives from the Tohono O'odham Nation, Mexico, and the United States recommended that this remarkable gathering should happen every two years.

The March 2016 tri-national symposium will address successes and continuing challenges of conserving the magnificent Sonoran Desert. The symposium will focus on cultural and natural resource issues, and Native American tribal perspectives, with a new theme:  Converging Trails: Past, Present, and Future of the Sonoran Desert.

A variety of special field trips are scheudled for Monday, March 7.  On Tuesday through Thursday evening, we are scheduling plenary sessions, a rich choice of breakout sessions, and ample networking time.  Wednesday evening will feature a sunset dinner in the Barry Goldwater Range (transportation provided). This year we are pleased to welcome the Arizona Native Plant Society to the Syposium for an all-day meeting on Tuesday. The Monday - Thursday schedule leaves out of town participants free to travel home on Friday.

Registration fees are $125 for the entire Symposium or $50 per day for single days; meals are included for each day registered.
Field trips are free.
