Where are our wetlands?

Tidal wetlands ringed most of the Bay prior to the mid-1800s. By 1998, more than 80% of wetlands had been lost to development. Today the WRMP tracks progress towards protecting and restoring remaining wetlands around the Bay.

Tidal wetland and channel with very high water overtopping most of the vegetation during a king tide. There is a wooden foot bridge with rails going over the channel with a small building along it.

How healthy are our wetlands?

Wetlands with clean water and healthy habitats offer more benefits to people and wildlife and are resilient to environmental hazards.

Who uses our wetlands?

Tidal wetlands provide habitat for fish, wildlife, and plants, recreational opportunities for people, and environmental benefits to nearby communities.

What we do

The WRMP improves wetland restoration project success and cost-effectiveness by implementing coordinated environmental monitoring across the region. The Program communicates scientific results to wetland managers, regulators, community members, and funders to enable adaptive management for healthy wetlands.

Our mission

The Wetlands Regional Monitoring Program (WRMP) delivers coordinated regional monitoring of the San Francisco Estuary’s wetlands to:

    1. Inform science-based decision-making for wetland restoration and adaptive management, and
    2. Increase the cost-effectiveness of permit-driven monitoring associated with wetland restoration projects.

Approach to partnership

WRMP implementation relies on collaboration with cities, counties, non-profits, Tribes, regulators, and restoration experts. The WRMP is committed to fostering partnerships with these groups to ensure all residents benefit from healthy tidal wetlands. This approach shapes all aspects of the WRMP including its operations and communication products.

    Monitoring Site Network

    The WRMP monitors three types of wetlands around the Bay: 1) mature, historic wetlands; 2) mid- to late-stage restored wetlands; and 3) recently restored wetlands. These three types offer insight about wetland evolution following restoration to inform future restoration and management.
