Ballona Parcel A. Trail is west of Lincoln Blvd. and just north of Ballona Creek

Ballona parcel B: the saltmarsh with the Westbluffs in the background. View from Jefferson Blvd. looking south.



NATIVE PLANTS THAT ARE FOUND IN ONLY ONE SECTION OF BALLONA

The Ballona Wetlands and uplands have been plowed, filled, drilled for oil and otherwise modified by man over the last century. Despite all of this disturbance, well over 150 kinds of native plants are found here. Two of the parcels now owned by the State Department of Fish and Game, A and C, are approximately 10 feet higher than their original elevation because they were used as dumping sites for wetland soil that was dug out of the marsh when Marina Del Rey yacht harbor was constructed in the early 1960's. Forty-five years later, these parcels have been recolonized by native wetland and upland plants, although with a smaller number of different types of plants. On the other hand, parcel B, which was not filled in with dredged mud and is mostly at its original elevation, has a very large number of native plants and plants that are exclusively found there. Finally, parcel D, which is the only parcel being developed by the Playa Vista company, and had been highly modified at the time plant surveys were done, still had a high number of natives although it had a small number of plants found only there.

Summary:

Parcel A: 53 total natives, 2 exclusive to parcel
Parcel B: 139 total natives, 38 exclusive to parcel
Parcel C: 40 total natives, 4 exclusive to parcel
Parcel D: 96 total natives, 13 exclusive to parcel
