San Diego Management & Monitoring Program


Threats and Stressors
Riparian Restoration and Arundo Removal


Project description

This project is to remove arundo donax and other non native plants located in an 11 acre 'old growth' riparian forest in the channel of the San Diego River. This area, received a great deal of arundo corms and stakes during the first El Nino storm series of 2016. They arundo stakes formed dikes and debris lines several feet high. Although the area has been cleared of arundo for several years, this flooding brought an inordinate amount of arundo stakes and corms into the riparian forest. They are all sprouting and need to be cleared out to get the infestation under control while it is small enough to be controlled with limited effort.
