Native Plants of the Route 90 Median

25 native plants are found in the median of the Marina Freeway, which includes both wetlands and uplands. The plant lists are from studies by the California Department of Transportation in 1995 and 2002.


The Route 90 median is a 300 foot wide by 1/2 mile long site between the highway lanes at which we discovered the wetland in 2002. This discovery forced CalTrans to elevate their bridge project, leaving several acres open for additional habitat or recreational use. BEEP sued CalTrans over the permits and secured restoration of additional wetlands. The unpaved portion of the CalTrans median land totals around 18 acres and is bounded by Culver Blvd. and Mindanao Way and we are working to design a way to reconnect this long "finger" of natural open space back to the rest of the Ballona Wetlands. The Route 90 open space is vegetated with Willow trees and mulefat, which are native to freshwater marshes, on the end nearest Culver Blvd., while the western portion is densely covered with saltbush and coyote bush which are native in drier uplands which surround marshes.
