Article abstract: The California least tern (Sternula antillarum browni, least tern) is a federally endangered migratory seabird which nests on sandy beaches around San Diego Bay. Urbanization, habitat loss, and abundant predators have negatively impacted the population which now requires annual management and monitoring to protect the species from extinction. One of the largest remaining habitat areas for least terns is the D Street Fill, located in Chula Vista, California, which is an approximately 80-acre area of dredge spoils that provides sandy dune habitat with low-vegetation height for least terns to nest. The San Diego Unified Port District (Port) and the U.S. Fish and Wildlife Service (USFWS) jointly manage the site, which requires annual invasive plant removal, management and monitoring of the least tern seasonal breeding and nesting, and avian and predator control efforts.
