Thirty volunteers with Tampa Bay Watch gathered at Desoto Park to fill the bags and line the shoreline to create "oyster bars" where oyster larvae settle and grow, eventually forming a natural reef. Tampa Bay Watch wants to restore the lost habitat systems of the bay, prevent further erosion of the shoreline, and improve water quality with natural biological filtration. The volunteers will wrap up work Friday and continue in the fall. The goal is 3,000 linear feet of oyster bars by the end of 2015.
