  • On Turning 20!

    puddlesApril 10, 2016

    San Diego NWR reached a milestone on April 10, 2016 – its 20th anniversary. Much has changed from the founding in 1996, when just over 1,800 acres of willow riparian and coastal sage scrub habitats were brought into permanent conservation within the National Wildlife Refuge System. The refuge now has grown to nearly 12,000 acres, with land purchases and donations that help support many listed and locally rare species. These lands also provide important landscape connections to other conserved lands in south San Diego County.
