The MPA Collaborative Network has recently formed an Estuary Working Group (EWG) in response to expressed compliance concerns that illustrated a need to dedicate more attention and resources to estuarine MPAs. This group is still growing with lots of direct outreach and sharing through Collaborative co-chairs and partners. The goal of the EWG is to facilitate conversations about estuaries that include or are adjacent to a state designated MPA and to ultimately address compliance issues with education and stakeholder engagement.

Here’s some more detail about our EWG:

The statewide EWG will be a subcommittee nested within the greater structure of the MPA Collaborative Network. The EWG will serve as a framework for sharing information and resources, connecting stakeholders, and discussing issues unique to estuarian MPAs. The EWG complements the Central Coast Wetlands Group (a research and monitoring consortium dedicated to coordinating the advancement of wetland science and management in California) by focusing on enforcement and compliance and education and outreach regarding estuarian MPAs by bringing together stakeholders with vested interest and expertise.

We have also compiled a list of 30 estuarine (see below) MPAs in California, or MPAs that overlap entirely with an estuary (e.g. lagoons, rivers, estuaries/esteros). Some examples of estuarine MPAs include San Elijo Lagoon in San Diego, Elkhorn Slough in Monterey, and the historical MPAs in San Francisco Bay.

In October 2020, we held an EWG virtual meeting where the Central Coast Wetlands Group (CCWG) presented their work. They provided an overview of their estuarine MPAs statewide project, funded by the Ocean Protection Council (OPC), to improve the long-term research and monitoring with standardized protocols and ultimately to improve management of estuary MPAs. Our upcoming meeting in early 2021 will include a discussion of compliance concerns unique to estuarian MPAs identified by stakeholders and community members during the MPA Community Compliance Forums held in each coastal county. This discussion will also include estuarine MPA enforcement data shared by allied agency partners.

We continue to expand the membership of the EWG. If you or someone you know should be involved, please reach out to aubrie@mpacollaborative.org to learn more and/or be added to the EWG mailing list!
