Elizabeth Hartwell Mason Neck National Wildlife Refuge was established in
1969, and became the first national wildlife refuge created specifically for
the protection of bald eagles. Once on the brink of extinction, the bald eagle
enjoys the safety of the refuge’s forests and shoreline for nesting and
foraging along the upper portions of the Potomac River and its tributaries.
Other species observed on the refuge include wood thrush, white-tailed deer,
groundhog, and wood duck.

Elizabeth Hartwell Mason Neck National Wildlife Refuge is adjacent to a
rapidly growing metropolitan area where habitat is constantly altered. The
refuge provides wildlife a relatively remote area of upland forests and
freshwater marshes that extend into the Potomac River. Great Marsh, a 207-acre
tidal freshwater marsh, is a valuable feature of the refuge, and is home to
one of Virginia’s largest great blue heron breeding colonies.
