Tijuana Estuary (Tijuana River National Estuarine Research Reserve)

Tijuana Estuary (Tijuana River National Estuarine Research Reserve) “A Wetland of International Importance” International Ramsar Convention, 2005
(617)

The Tijuana River National Estuarine Research Reserve preserves, protects, and manages the natural and cultural resources of the Tijuana River Estuary by focusing on research and education with compatible recreation and resource use. The Reserve encompasses beach, dune, mudflat, salt marsh, riparian, coastal sage scrub, and upland habitats surrounded by the growing cities of Tijuana, Imperial Beach, and San Diego. Critical issues confronted by the Reserve include habitat restoration, endangered species management, management of the wastewater from Mexico, sediment management, and the integration of recreation and habitat conservation and restoration.

Did you know our researchers are actively monitoring water quality and biological processes in the Estuary? 🌾

Our team is often out in the field working on GPS surveys and weather and telemetry station maintenance. They are also hard at work in the laboratory, doing data analyses and writing research reports. Learn more about our long-term monitoring projects on our website!

Can you spot invasive species in Southern California?

We have quite a few rare and unique species in the estuary, but invasive plants can alter the environment and, in some cases, impact the breeding structure or forage resources for those species.

In general, invasive plant species compete with and displace native plant species. Our Stewardship Program works toward sustained control of invasive plants, like the Black Mustard shown here.

Curious about what's going on behind our "plant rehabilitation" signs?

Last winter and spring, we cleaned up some overgrown saltbush to make room for more native plants. As part of a years-long habitat-enhancement project, we planted mainly bladderpod, California sagebrush, white sage, and California Buckwheat. Biodiversity makes ecosystema strong! 🌱

One of our missions is to protect the estuary from excess sedimentation.

Throughout Southern California, salt marsh habitats are jeopardized by stormwater flows and sedimentation. In the Tijuana River Estuary, tidal channels and salt marsh habitat have been significantly impacted by sedimentation.

The Goat Canyon Sediment Basins were constructed in 2005 to stop excess sediment flowing from a highly disturbed canyon landscape in Mexico. These basins capture up to 60,000 cubic yards of sediment and solid waste each winter and are cleaned out every fall. The Stewardship Program plays an active role in managing this facility.

Learn more about the basins on our website!
