San Diego River Watershed Invasive Non-Native Plant Control & Restoration
Document Type
MND - Mitigated Negative Declaration
Document Description
This project proposes a watershed based invasive non-native plant control and riparian restoration program on the San Diego River Watershed. The riparian habitat is estimated to be 6,642 acres with an additional 354 acres occupied by invasive non-native plants. Total riparian habitat after control/restoration would be 6,996 acres. The project involves removal of Arundo Donax and re-vegetation by planting native species. Arundo and other invasive non-native plants pose a serious threat to the native flora and fauna, and are a significant flood and fire risk to the community. Arundo alters the flood regime by blocking flows with its thick growth, creates unstable banks due to its poorly developed root systems, and contributes to bridge and flood control structure failure. The typical restoration process for Arundo begins in the Fall, which avoids/minimizes impacts to the breeding/reproductive season for wildlife, fish and native plants.
