San Francisco Bay is in dire need of over 545 million tonnes of dirt by 2100 to save its marshlands from rising sea levels.
The US Army Corps of Engineers is testing a "shallow placement" method, allowing tides to distribute dredged sediment, aiming for a less invasive restoration.
This project is crucial for endangered species like the Ridgway’s rail, and if successful, could redefine ecological restoration efforts in the area.
Why this matters:
Marshlands act as natural buffers, absorbing storm surges and high tides, thereby reducing the risk of flooding to coastal communities. By restoring these areas, the Bay Area enhances its natural defenses against the increasing threat of sea level rise and extreme weather events associated with climate change.
Researchers from MIT have hidden audio and video recording devices all over Tidmarsh Wildlife Sanctuary in Plymouth, as a way to create a virtual world that helps students and others learn more about the marsh.
San Diego’s proposed redevelopment of Mission Bay Park’s northeast corner could include significantly more marshland if city officials embrace new proposals from local environmentalists concerned about sea level rise.
