How we work with nature to bring back the Bay’s historic salt marshes

A typical salt pond looks like a moonscape in the dry of summer.

Digging in the Mud

We launch restoration by digging holes in the dirt levees surrounding ponds, and Bay tides rush in to cover crusted salt flats.

 

 

The tides bring in mud, nutrients, seeds, fish, and other Bay creatures.



 

Vegetation Emerges

Once enough sediment has built up, it can support snails, shellfish, and other creatures, and the growth of marsh plants – so seedlings begin to pop up.

 

Animals Find Refuge

We are now seeing two key San Francisco Bay endangered species living and breeding in our restored wetlands. Scientists caught sight of the animals earlier than was expected, less than a decade after restoration began.
