The aim of the LA River STEW-MAP is to produce a publicly available, online stewardship database and map of groups and organizations in the Los Angeles River watershed at work to conserve, manage, monitor, transform, advocate for, and/or educate the public about their local environments. This can help potential volunteers, public agencies, funders, and others find stewardship organizations throughout the LA River watershed. STEW-MAP can also show where there are gaps and concentrations of stewardship. LA River STEW-MAP follows a similar study from 2014-2015 that encompassed all of Los Angeles County.
