Protecting and preserving the Tijuana Estuary
Since 1979, the Tijuana Estuary Foundation, formerly the Southwest Wetlands Interpretive Association (SWIA), has led efforts to understand, protect, and restore one of our most vital yet vulnerable ecosystems - the coastal wetlands of the Tijuana Estuary.
Through this work, we helped establish the Tijuana River National Estuarine Research Reserve (TRNERR), which has become a cornerstone for environmental science, education, and public engagement. Decades of solutions-oriented research at this living laboratory, paired with thoughtful conservation, strong partnerships, and community support, have helped preserve one of our planet’s richest natural resources and transform it into a model for connecting people with nature.
Our Mission
Our mission is to support the Tijuana River National Estuarine Research Reserve's programs to help them be efficient, effective, and sufficiently funded for the benefit and enjoyment of all who rely on these unique natural and cultural resources throughout the Southern California Bight.
Vision Statement
Our vision is that the Tijuana River National Estuarine Research Reserve's programs to restore and conserve coastal wetlands and connected natural lands are fully supported, so that these lands are appreciated and protected in perpetuity for everyone.

About Us
The Tijuana Estuary Foundation is TRNERR's vital nonprofit partner.
The Tijuana Estuary is the largest estuarine system in Southern California. In the late 1960's and 1970's, the City of Imperial Beach envisioned dredging the estuary and constructing a marina. Citizens teamed with scientists and federal and state agencies to oppose the marina. They envisioned an alternate future based on conservation and restoration.
In 1980, the estuary was designated the Tijuana Slough National Wildlife Refuge. In 1982, the estuary became the 10th Estuarine Research Reserve in the nation. In 2005, the estuary was selected as a Ramsar site. A Visitor Center was implemented in 1988.
Research and applied management have guided restoration projects in the north and south arms of the estuary, increasing the tidal prism (the amount of water coming and going with the tides). The robust education program serves community schools, grades K-12.
The Reserve has a full time Research Coordinator, a Coastal Training Program Coordinator, Reserve Manager and an Education Coordinator.
