Ravenna and pampas grass removal in the Grand Canyon

September 21st, 2022
RiversEdge West is partnering with the National Parks Service and Mariposa Ecological and Botanical Consulting for a project involving the mapping and removal of Ravenna and pampas grasses along the Colorado River in the Grand Canyon. With the help of funding from the Arizona Watershed Protection Fund and The Grand Canyon Fund, this project will include two trips to map, monitor, and remove Ravenna grass and pampas grass along the river. The timing for this project is critical as these grass populations are currently well-mapped and small, and complete eradication is feasible within the next few years.
 
Ravenna grass is an invasive, non-native species that was planted as an ornamental grass within Glen Canyon National Recreation Area in the 1970s. It was first documented in the Grand Canyon in 1981 and spread rampantly from 1987 to 1992. The biggest concern is that it could spread into side canyons and impact sensitive habitats such as springs, seeps, and hanging gardens.
 
This type of collaboration is essential to be able to implement this project to continue to help protect our national treasures. Stay tuned for updates after both of the trips!
