our 2012 annual report and mid-project update summarizing MarineFisheries’ progress after three years of work to restore eelgrass to Salem Sound and Boston Harbor, funded as partial mitigation for Algonquin’s HubLine pipeline impacts to eelgrass in Beverly Harbor. Our project began in 2010 when we received funding to restore 1.8 acres of eelgrass based on test planting performed in 2009 by Battelle. In 2010 we assigned the project manager and hired one full time project staff member, began project planning and worked on site selection and reconnaissance in the field. In 2011 staff was increased to two full time staff on the project in addition to the project manager. In 2011 we initiated full scale planting at the pipeline impact scar in Beverly and conducted additional test-plots and site selection data collection throughout Salem
