The San Diego Natural History Museum, San Diego Audubon Society, U.S. Fish and Wildlife Service, and naturalist Hector Valtierra will be leading a free, bilingual (Spanish and English) in-person event to record the biodiversity found at Tijuana Slough National Wildlife Refuge. No prior experience is necessary, but an RSVP is highly encouraged as there is limited seating. Sign up by emailing Park Ranger Nancy Fernandez at Nancy_Fernandez@fws.gov.
