New land created by pumping sediment into a dredging cell at Rainey. Visitors can now walk down a boardwalk to the site and see bacopa, spikerush and three-square grasses fanning out along the new mud bed. In times of lower water, birds, raccoons and alligators leave their tracks across the new mud, and on the primary test site, marsh vegetation – the backbone of the wetlands – has begun to take hold. “It really works – we’re doing it.”Īs evidence, throughout their dredging cells, the pair now sees alluvial flows – mini deltas of mud fanning out across the marsh. “The learning curve has been rather bumpy,” said Karen, expanding upon the challenges of figuring out the finer points of moving sediment, but she quickly added that progress was improving. Initiated and partially funded by TogetherGreen, a collaborative project between Audubon and Toyota, the John James’ work officially began on November 22, 2010, and for the past year Karen and Timmy have become part-time dredge operators in an effort to combat erosion in the sanctuary.Īs with most new ideas, progress started slow. Put simply, the pair hopes to demonstrate that small, independent dredges have the potential to create new land in areas where erosion and subsidence currently threaten wetlands and property lines. Rainey Wildlife Sanctuary, where the dredge operates. For this, enter the John James, a 24-foot dredge operated by Karen Westphal, Audubon’s Atchafalaya Basin program manager, and Timmy Vincent, senior sanctuary manager for the Paul J.
