To prevent further erosion at the Slade Dale Sanctuary in Point Pleasant, dozens of volunteers helped stabilize the shoreline using a technique that has never been done before in New Jersey. On Saturday, American Littoral Society, in partnership with Princeton Hydro, Borough of Point Pleasant, New Jersey Nature Conservancy, New Jersey Corporate Wetlands Restoration Partnership, and the Point Pleasant Rotary Club, organized dozens of volunteers to restore the shoreline and prevent further erosion at the Slade Dale Sanctuary using recycled Christmas trees.
As one of only a few areas of open space left in Point Pleasant, the 13-acre Slade Dale Sanctuary is an important part of the local ecosystem, and is home to a number of unique animals and plants. This waterfront preserve along the North Branch Beaver Dam Creek is predominantly tidal marsh, which provides habitat for various birds, including osprey, as well as passive recreation opportunities for the community.
Unfortunately, the Slade Dale Sanctuary is disappearing. Since 1930, the shoreline of Slade Dale Sanctuary has retreated approximately 300 feet, equal to the length of a football field, and the channels into the marsh have increased in number and size, according to a study we conducted on behalf of American Littoral Society, for which we provide engineering and natural resources management consulting services.
In order to stabilize the shoreline, restore the marsh, and enhance the ecological function and integrity of the preserve, Princeton Hydro developed a conceptual and engineering design using living shoreline features to enhance ecological value and reduce erosion. The final conceptual plan for restoration uses tree vane structures to attenuate wave action, foster sediment accretion, and reduce erosion along the coast.
To implement this vision and begin building back marsh, the project team is constructing several Christmas tree breakwaters and Christmas tree vanes that mimic naturally occurring debris structures in tidal systems and enhance habitat opportunity and shelter for aquatic life. Volunteers came together on Saturday, May 11 to help with the construction. The Mayor of Point Pleasant Robert A. Sabosik also attended the event, “The Barnegat Bay is an attribute that we all enjoy, and it’s something we have to protect.”
After the 2018 holiday season, the Good Sheppard Lutheran Church in Point Pleasant provided space to collect and store donated Christmas trees, which were then moved to the marsh a few days before the event. On the day of the event, recycled Christmas trees were transported from their staged locations on the marsh to the breakwater sections that were previously installed in the water. To transport them across the water to the pilings, volunteers used two methods: by walking a skiff boat loaded with trees through the water to the pilings or by forming assembly line from the shore to pilings to guide floating trees through the water (check out the album below!). Then, they stuffed the Christmas trees between the pilings, securely tied them down, and staked Christmas trees directly into the creek bottom. For extra assurance, the placed and tied heavy bags of used oyster shells on top of the tree line. Oyster shells were donated by local Monmouth County restaurants in an effort to reduce waste streams.
“We really enjoyed participating in this event with American Littoral Society and so many wonderful volunteers,” Christiana L. Pollack, GISP, CFM, Princeton Hydro’s Project Manager for this restoration effort. “It is so wonderful to see this project coming to fruition. We’re so proud of our partnership with American Littoral Society and our combined efforts to revitalize and rehabilitate our precious coastal habitats.”
Members of the media were invited to attend the volunteer event. News 12 New Jersey covered the event and aired a story on it during their Sunday news broadcast, and NJTV News will be airing the story in the near future.
