Marshes on the Margins

The tidal wetlands of Southern California are some of the most threatened estuarine systems on the west coast.

The high urbanization of wetlands in Southern California places them under serious threat of habitat transformation and loss in the face of sea level rise. Further, these systems are highly understudied, particularly in regards to inlet dynamics.


This project identified how the dynamic estuarine systems of Southern California will be affected (physically and biologically) by sea level rise and determined how and where nature-based solutions can be used to provide resilience to those effects.


By building upon the Southern California Wetland Recovery Project’s collaborative structure, the project developed guidance and tools that will fill a crucial need in wetland management.


I. Identify vulnerability

Model, analyze and quantify the vulnerabilities and response of intermittently-open estuaries and tidal wetlands to sea level rise.


II. Develop natural & nature-based adaptation strategies

Identify and quantify opportunities for natural transition zone restoration and construction of nature-based features.


III. Implement tools at case-study sites

Implement and refine developed products by applying them to wetland systems.


IV. Stakeholder involvement

Leverage existing scientific, management and practitioner networks to gain input.


V. Project management & administrations
Efficiently manage the project to complete milestones & to collaborate among the project’s team.
