Salt Ponds Reborn: Wetlands Thrive Again
6 Oct
Summary
- Former salt ponds transformed into thriving tidal wetlands.
- Restoration efforts created vital habitat for 80 bird species.
- Native plants and fish nurseries emerged within a year.
For decades, parts of South San Diego Bay were dominated by former salt ponds, isolated from natural tidal flows. A partnership involving federal, state, and local agencies began restoring these landscapes in the late 2000s.
By 2011, approximately 300 acres were restored by reshaping degraded areas and breaching levees to reintroduce tidal influence. This work reconnected the ponds to the bay and Otay River channel.
The transformation created open water, intertidal habitat, and upland marsh. Post-construction monitoring revealed a significant ecological comeback, with 80 bird species, 22 fish species, and 10 invertebrate species utilizing the revitalized site.
Beneficiaries included migratory and resident birds, with species like the California least tern and light-footed Ridgway's rail finding crucial habitat. The restored channels also provided essential nursery and spawning areas for fish and invertebrates.
Native plants, including eelgrass, began returning within a year. The project successfully supported breeding for the endangered light-footed Ridgway's rail by 2016. The Bayside Birding and Walking Trail now allows public observation of this ecological recovery.
