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.
