This is the ancestral land of the First People, the Kumeyaay.

In 1982, the Tijuana River National Estuarine Research Reserve was established. Its goal was, and still is, to enhance scientific collaboration and research within the watershed that is split between two countries, Mexico and the United States. Three quarters of this massive water basin lies in Mexico, making this collaboration even more necessary and important.

Over time, various research partnerships were created to study erosion, sedimentation, and tropicalization. More recently, geography professors have studied erosion and sedimentation in Los Laureles Canyon in Tijuana, a sub-watershed that flows right into Border Field State Park. When it comes to the ocean, tropicalization is another significant collaboration topic.

In this episode we’ll hear from some of the geographers and scientists working back and forth across the border, some of the challenges and rewards they’ve encountered, and ways to make studying this landscape and marine environment more accessible.

Divided Together is a California State Parks podcast series for Border Field State Park, brought to you by California State Parks Foundation, Parks California, and the generosity of an anonymous donor.
