Sediment - Is there sufficient sediment available in the S Bay to support marsh development?
Bird Use – Can the existing # and diversity of Mig and breeding birds still be supported?
Other species – How to restore tidal areas to benefit non-avian species in marshes and adjacent water bodies?
Mercury – Will Hg be mobilized into the food web of F Bay at a greater rate than before?
Water Quality – How will ponds affect water quality, and food web in S Bay?
Invasive Species – Invasive Spartina, corvids, CA Gulls, etc.
Public Use – will trails and other public access negatively affect wildlife species?
Will produce scenarios based on management changes - including restoration
Produced model grid from bathymetric data
Calibrated the hydrodynamic model (salinity, currents, tides) and did successful coarse and fine grid simulations.
In process of developing a sediment transport component of the model.
Also will be modeling climate change
Grid with avg. resolution 25 m

Continue vegetation studies at Pond A21
Begin sediment accumulation studies at Pond A6 using same techniques as at Pond A21 (sediment pins and modified filter paper method)
Record vegetation at each pin location and mark with GPS to verify plant species with satellite imagery.

Goal is to evaluate how the benthic invert community has changed in response to restoration actions.
Use already collected benthic samples from 1993-1995 (pre-restoration) and 2006-2008 (after restoration started).
Will evaluate differences in grazing rate, abundance, community structure in pre- and post-restoration samples
Develop database of existing bird survey data
Synthesize existing survey data to establish baseline numbers, trends, and nest success.
Awarded to Mark Herzog of PRBO
Develop a data needs/gaps assessment
