Maine, Hadley Point
ME57.1United States of America
Stretch of shoreline on the north end of Mount Desert Island, Maine, within the Mt Desert Narrows. The beach is frequented by locals year-round, and tourists in the warmer months. There is a public boat ramp that breaks the seagrass bed up into two main sections, and just outside of the deepest extent of the seagrass there is a boat mooring field. The ramp is used daily in the summer by recreational boaters, kayak guides running trips in the Mount Desert Narrows, and local mussel and oyster aquaculture businesses. The seagrass bed occupies a small subset of its previous range, which once extended from Hadley Point westward along the shore all the way to the island causeway but experienced massive aerial losses in the early 2000s. In the 2010s, a restoration effort led by researchers at the Mount Desert Island Biological Laboratory (MDIBL) planted seagrass at the site, and in the time since a few acres of seagrass has re-established itself. Locals have commented on the impressive growth of the bed in the last 5-7 years. The tidal range at the site is around 13ft, with the grass occupying a range of ~0-5ft depth at mean low tide. There are also large numbers of blue mussels at the site, both around the outside and interspersed within the seagrass bed. The sediment at the site transitions from cobble and sand high on the shore to fine silt and mud in the intertidal and shallow subtidal. Alongside recreational uses, Hadley Point is a oft-used location for individual commercial clamming and worming.
