Threats and Stressors

Riparian Restoration and Arundo Removal

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.

Invasive plants

Goal: The overarching goals for addressing invasive plant species in the MSPA are to: (1) Protect Conserved Lands from new or expanding invasive plant species; (2) Detect new invasive species and new invasions early on and control them before the plants have a chance to establish; (3) Address invasive species using the response appropriate for the level of invasiveness (level 1 through 5) as defined in the Invasive Plant Strategic Plan (IPSP)

regional and/or local NFO 2017, 2018, 2019, 2020, 2021
MGT-IMP-IPSP INVPLA-1

Management units: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11

From 2017-2021, continue implementing the IPSP by removing Levels 1, 2, and 3 invasive plant species before their distribution becomes too abundant to control.
