Despite fluctuations in acreages between years, the marshes and mudflat south of the San Mateo bridge appear relatively stable between the period 2009 – 2021, in that the relative proportions between different habitat types have not changed significantly. Within a number of restored ponds (e.g.,

This report outlines the preliminary results of the 2019 update to the original Habitat Evolution Mapping Project (HEMP). HEMP mapped the marshes and mudflats south of the San Mateo bridge yearly between 2009 and 2011.
The Santa Clara Valley Water District’s (SCVWD) Healthy Creeks and Ecosystems’ Environmental Enhancement Grant Program funded the planning and implementation of tidal marsh-upland transitional plant community restoration at former salt pond A6 (Figure 1 below).
In this report we document activities from March 31, 2012 to June 30, 2012, by task, and summarize the project’s current results. This is the sixth quarterly report and the first annual report for the project.
This report details the results of a three year project aimed at developing methods for tracking long term changes to marsh habitats and mudflats for the South Bay Salt Pond Restoration Project (SBSPRP).
Map Book for Final Report
In San Francisco Bay, three former salt pond complexes (Alviso, Eden Landing, and Ravenswood) have been decommissioned, i.e., taken out of commission, and are planned for marsh restoration.
We conducted bathymetric surveys to map substrate elevations using digital elevation models and surveyed colonizing Pacific cordgrass (Spartina foliosa).

In 2010 the U.S. Geological Survey (USGS) completed three cruises to map the bathymetry of the main channel and shallow intertidal mudflats in the southernmost part of south San Francisco Bay.
Our goal was to evaluate communities of benthic invertebrates and shorebirds on the Alviso mudflat prior to breaching Pond A6 to serve as the baseline for future assessments of potential impacts.
We determined that the intertidal mud flat study site adjacent to Ravenswood Pond SF2 was already at carrying capacity for small shorebirds during spring migration.
