As part of the latest push to restore the ailing Delta, a 646-acre wheat and corn farm here is expected one day to metamorphose into a recreational and habitat oasis complete with kayak launches, hiking trails and a home for endangered species.

The area, off the Byron Highway between Oakley and Brentwood, will provide a launch spot to explore the Delta, as well as trails for hikers. The East Bay Regional Park District paid $6.1 million in late January to buy the land for the project, which is likely to cost millions more to carry out over many years.
