2005

The erosion has created a channelized area, which will reduce the island by about a ½ acre during the 2005-06 winter if nothing is done by winter.  Dr. Blueford brought this up to the City of Fremont, Annabell Holland, Director of Parks and Recreation.  After several meetings it was agreed that the Math Science Nucleus could take the lead on using community groups for restoration with the help of staff from the City, especially to transport people and supplies to the island. 

Ranger Sandy Ferriera leads a group of California State Univeristy, East Bay out to Duck Island (in background) to work on erosion control along the banks.

Since the need is critical the Math Science Nucleus has teamed up with two Eagle Scout projects and California State East Bay Teacher Education and completed 3 projects in October, 2005 to try and stop the erosion for the upcoming winter as a stop gap strategy.  Tules from Tule Ponds at Tyson Lagoon (a wetland Facility managed and being restored by the Nucleus) was used as “plugs” to not only stop erosion by helping to capture silt and mud from the eroding banks. 

Before Storms through wave action have cause the bank of the entire island to erode valuable land.  Trees and tules once lined this area.  The root system helps to bind the soil	After Restoration includes planting willows and planting tule  to increase sedimentation in this area.  The root systems of both plants will help decrease erosion.

Teacher plants tules between straw waddles and rip rap (rocks)	Willow stakes help to keep wattles in place and will grow into young willow trees	Tules and willows helping to trap sediments to help stop erosion
