In 1978, Ruth Lansford formed Friends of Ballona Wetlands to protect what remained of the 2,000 acres of wetlands that had been drastically affected by housing and development during the 20th century. With their nonprofit status in place, Friends of Ballona Wetlands took up a battle against a series of developers, using litigation and activism to push for preservation of the area. Finally, in 2003, the State of California, the developer of Playa Vista, and the Friends reached an agreement to save 600 acres of the wetlands. Through their relentless efforts, the Friends of Ballona Wetlands have become a leading voice in the struggle to protect the wetlands, working with other NGOs, creating community restoration and educational programs, and advocating for the environment.
