In recent years, environmental stewardship has been emphasized as one solution to social-ecological sustainability concerns, especially at the local scale.

This study compared the mission statements of environmental stewardship groups in the Los Angeles River Watershed to previously proposed definitions and frameworks of organizational environmental stewardship to see how well they were reflected.
