Tijuana River Mouth State Marine Conservation Area (SMCA)

Like state and national parks protect wildlife and habitats on land, marine protected areas (MPAs) conserve and restore wildlife and habitats in our ocean. Under the California Marine Life Protection Act (MLPA) passed in 1999, California began a historic effort to establish a science-based, statewide network of MPAs through a collaborative effort that includes the California Department of Fish and Wildlife and California State Parks. California is taking a regional approach to the design and implementation of MPAs, and has divided the state into five regions: the north coast, south coast, north central coast, central coast and San Francisco Bay.

MPAs contribute to healthier, more resilient ocean ecosystems that can better withstand a wide range of impacts such as pollution and climate change. By protecting entire ecosystems rather than focusing on a single species, MPAs are powerful tools for conserving and restoring ocean biodiversity, and protecting cultural resources, while allowing certain activities such as marine recreation and research. There is a global body of scientific evidence about the effectiveness of marine protected areas and reserves to restore marine ecosystems (http://www.piscoweb.org).

In the waters adjacent to Border Field State Park, there is one MPA, Tijuana River Mouth State Marine Conservation Area (SMCA).

  • Tijuana River Mouth State Marine Conservation Area (SMCA)
    • This area is bounded by the mean high tide line and straight lines connecting the following points in the order listed except where noted:
      32° 34.00' N. lat. 117° 07.98' W. long.;
      32° 34.00' N. lat. 117° 09.00' W. long.;
      32° 31.97' N. lat. 117° 09.00' W. long.;
      thence eastward along the U.S./Mexico Border to
      32° 32.06' N. lat. 117° 07.48' W. long.
    • The Tijuana River Estuary is one of the few salt marshes remaining in Southern California where over 90% of wetland habitat has been lost to development. The site is an essential breeding, feeding and nesting ground and key stopover point on the Pacific Flyway for over 370 species of migratory and native birds, including six endangered species. – Tijuana River National Estuarine Research Reserve
    • Permitted/Prohibited Uses: Take of all living marine resources is prohibited EXCEPT the recreational take coastal pelagic species, except market squid, by hand-held dip net only and the commercial take of coastal pelagic species, except market squid, by round haul net only.

This information does not replace the official regulatory language found in California Code of Regulations, Title 14, Section 632, including commercial allowances and restrictions.

  • A fishing license is required for any fishing.
  • All existing take regulations still apply in addition to the ones listed above.
  • Unless otherwise stated, all non-consumptive recreational activities are allowed.
