The Colorado River Terrestrial and Riparian Group (CRTR) helps facilitate communication and information sharing for individuals or groups working with native restoration and natural resources monitoring and research related to the Lower Colorado River Watershed. 

Organized by the Bureau of Reclamation (specifically, the Lower Colorado River Multi-Species Conservation Program (LCR MSCP), an annual meeting is hosted by CRTR for any and all groups working on the river. The 2013 CRTR meeting will be held from January 29-31 at Harrah’s in Laughlin, NV.  No lodging is provided but cheap options are readily available in the city of Laughlin.
