Public access to the bay and wetlands, with walking trails and educational exhibits about the area's ecological resources, is provided at the Chula Vista Nature Center operated by the city of Chula Vista.

Agriculture and river development, flood control, and waterway diversions have resulted in the drainage of large areas of the wetlands, reducing their ecological values.

A constructed wetland or wetpark is an artificial wetland, marsh or swamp created as a new or restored habitat for native and migratory wildlife, for anthropogenic discharge such as wastewater, stormwater runoff, or sewage treatment, for land reclamation after mining, refineries, or other ecological disturbances such as required mitigation for natural wetlands lost to a development.

* Environmental classification of mangrove wetlands of India.

* Article 1. 1: "... wetlands are areas of marsh, fen, peatland or water, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or salt, including areas of marine water the depth of which at low tide does not exceed six metres.

Artificial drainage of low-lying wetlands generally involves one or both of two different practices: a ) excluding water flowing from high areas from entering the low-lying area, and b ) pumping out water which does manage to get into the low-lying area.
