Eelgrass

• Work in collaboration with San Francisco State University continues looking at seeding and whole plant propagation techniques and if bat ray fences give the seeds a better chance of survival.
• Work funded by San Francisco Foundation in collaboration with San Francisco State University began in January 2007 to look at how water depth relates to eelgrass restoration success. This work includes:
• Planting eelgrass at four depths (+1, 0, -2 and -3 feet tidal heights)
• Planting seeds, seedlings and whole plants to see which has the highest success rate.
• Modeling bay circulation to look at potential seed dispersal
• Core samples will be taken to look at the differences between species diversity inside and outside eelgrass beds.
• Plans are in place to plant 500 adult shoots and 500 seeds between September 2007 October 2008.
• We are currently mapping the distribution of eelgrass within the Sanctuary using kayaks (rentals donated by Sea Trek) and GPS units.
