GCPBA RiverNews 04.22.13 – Wildlife Census Project in Grand Canyon

April 2013

Three wildlife census research projects are underway along the Colorado River in the Grand Canyon.  Data is being gathered regarding the numbers and locations of certain mammals, birds, and snakes.  River runners are asked to help by collecting data as they make their way downriver.

This survey program was initiated by Grand Canyon River Runners Association. GCRRA recruited and worked with the involved scientists, developed a variety of supporting materials (including photos and drawings), coordinated the project with the outfitters, and posted detailed information about it at

GCPBA encourages interested boaters to visit the above web site and consider supporting this important project.

The following links describe the researchers, provide some background information about the animals they are studying, and include log sheets for you to record data about your sightings.  Log sheets should be mailed to the addresses provided.  Please print the information, take it with you downriver, and help them as best you can.
