Past Symposia:

 

The 16th annual Research Insights in Semiarid Ecosystems (RISE) Symposium will be held Saturday, 26 October 2019, 8:30 AM to 3:00 PM on the University of Arizona campus.  The objectives of the symposium are to share recent results of research at the USDA-ARS Walnut Gulch Experimental Watershed (WGEW) and the University of Arizona Santa Rita Experimental Range (SRER), to encourage future research activities at the WGEW and the SRER, and to promote the WGEW and the SRER as outdoor scientific laboratories.

The Symposium will feature invited speakers presenting recent or on-going research on the WGEW, the SRER or other outdoor laboratories in the region. There will be time for questions from the audience, which will consist of federal agency, NGO (non-governmental organization) and university researchers, students, and stakeholders from southern Arizona.
