A globally rare habitat, which was once abundant, has now been largely destroyed for lumber, fuel, and through the conversion of land to agriculture. The largest cedar swamp remaining (11.9 acres) is at Marconi Station in Wellfleet, MA, accessible by means of a boardwalk. Atlantic white cedar swamps are found only in a 100-mile wide strip on the Atlantic coast and are home to a variety of plants and wildlife, some rare. The photogenic red patches of water may be due to a temporary algae bloom.
