Mary's Point is a
1,200 hectare wetland in New Brunswick
, Canada
.
It is at
the head of the Bay of
Fundy
, approximately 40 km south of Moncton
.
Designated
a Ramsar
wetland of international importance on May 24, 1982, it is also
part of the Fundy biosphere
reserve established in 2007, which also contains the Shepody Bay
wetland. It was also the first Canadian site
in the
Western
Hemisphere Shorebird Reserve, as part of the
Bay of Fundy
Hemisphere Shorebird Reserve. It is within the Shepody Bay
National Wildlife Area, which
is administered by the
Canadian Wildlife Service.
Mary's Point is an important staging area for
shorebirds migrating from the Canadian subarctic to
South America during the fall,
supporting up to two million
Semipalmated Sandpipers annually, or
nearly 75% of the global population of this species, as well as
millions of birds of other species.
Approximately 940 hectares of the intertidal mudflats are
under jurisdiction to the province of New Brunswick. Another
107 hectares are owned by the
Government of Canada, including the
"most critical sites used by the large roosting flocks of
shorebirds during high tide". The remaining portion, covering most
of the salt marsh, is privately owned. The federal government has
attempted to purchase the land, but has been spurned.
The site was a stone
quarry in the
1900s.
Geography
This open
peninsula ranges in elevation
from 2 m below sea level to 10 m above sea level,
protruding into Shepody Bay. It is characterized by extensive
intertidal
mudflats, with gravel beaches
bordering terrestrial habitats and shallow marine areas.
In 1979,
Ducks Unlimited Canada
established a 20 hectare waterfowl impoundment adjacent to the
salt marsh.
Fauna
This site exhibits "the world's highest known density of the
crustaceans Corophium volutator",, up to 60,000 per
square metre during their reproductive cycle, which supports large
populations of migratory shorebirds. During August, up to two
million Semipalmated Sandpipers may use Mary's Point as a staging
area, and as many as 200,000 may be present at any time during
migration.
These double their weight to 40 grams
before continuing their migration by flying to the North Atlantic
, which winds carry them to the northern coast of
South America in two to four days.
Thousands of birds of other species also use Mary's Point as a
staging area, including the
Black-bellied
Plover,
Least Sandpiper,
White-rumped Sandpiper,
Short-billed Dowitcher,
Semipalmated Plover,
Red Knot,
Sanderling and
Dunlin.
Also, small populations of
American
Black Duck,
Ring-necked Duck
and
Blue-winged Teal breed at the
impoundment established by Ducks Unlimited.
