January 12, 2018 2016RptCoverThumbnail

The SoCal Urban Wildlife Project, centered at the San Diego Refuge Complex, worked with 10 partner organizations and engaged more than 32,000 students, teachers, volunteers and community members. The project serves a metropolitan area of more than 17 million people who represent the projected racial and ethnic mix expected in the United States in 2060. The report includes in-depth statistics and shows how SoCal and its partners provided the stepping stone for many urban residents to experience nature for the first time. You can read the full report here.
