Global Invasive Species Database: management information

[Wikipedia] Greater Middle East native, Invasive: Arundo donax is a tall perennial cane. It is one of several so-called reed species. It has several common names including giant cane, elephant grass, carrizo, arundo, Spanish cane, Colorado river reed, wild cane, and giant reed. Arundo and donax are respectively the old Latin and Greek names for reed.[3] Arundo donax grows in damp soils, either fresh or moderately saline, and is native to the Greater Middle East.[4][5] It has been widely planted and naturalised in the mild temperate, subtropical and tropical regions of both hemispheres, especially in the Mediterranean, California, the western Pacific and the Caribbean and is considered invasive in North America and Oceania.[6][4][5][7][8] It forms dense stands on disturbed sites, sand dunes, in wetlands and riparian habitats.

[Cal-IPC] Invasive: Arundo donax (giant reed) is a tall perennial grass (family Poaceae) that typically forms dense stands on disturbed sites, sand dunes, riparian areas, and wetlands. It has invaded central California River valleys in San Luis Obispo and Monterey counties, the San Francisco Bay Area, the Sacramento and San Joaquin River valleys and is also increasing in the North Coast region. Arundo donax is threatening California?s riparian ecosystems by outcompeting native species, such as willows, for water. Cal-IPC Rating: High (link added by Mary Ann Machi)
