The Tantramar Marshes also known as the Tintamarre National Wildlife Area is a tidal saltmarsh around the Bay of Fundy on the Isthmus of Chignecto. The area borders between Route 940, Route 16 and Route 2 near Sackville, New Brunswick.
At 20,230 hectares, the marsh is one of the largest on the Atlantic coast of North America. The marshes are an important stopover for migrating waterfowl such as semi-palmated Sandpipers and Canada Geese. Now a National Wildlife Area the marshes are the site of two bird sanctuaries.
The name Tantramar is derived from the Acadian French tintamarre, meaning 'din' or 'racket', a reference to the noisy flocks of birds which feed there.
The marshes are a broad expanses of flat land just above mean sea level. The soil consists of silts deposited by centuries of tidal flooding. Drainage is poor and there are slow-moving meandering rivers, shallow lakes and bogs, which favours the growth of sedges and tamarack. The marsh's intertidal zones provide a habitat for many species of freshwater and estuarine life. It is drained by the Aulac, LaPlanche, Missaguash, and Tantramar Rivers.
History and economy of the marshes
For a full account of human activity on the marshes, see the History of Sackville.
Before the arrival of Europeans, well-traveled portage routes connected the Bay of Fundy with the Northumberland Strait. Migrating from Port Royal in around 1671, Acadian established a village in the area (which they called Beaubassin). They founded a number of scattered settlements on higher ground, and created the dykes and sluices which converted the salt marshes to fields and pastures. Following the Battle of Fort Beauséjour which market the end of the battle for Acadia between the British and French, it was the site of the beginning of the expulsion of the Acadians in 1755. Six years later the British resettled the area, and continued to convert the marsh to arable land.
As time went on land ownership became consolidated a Commission of Sewers was established which was crucial to the economy. By the mid-1800s 10,000 hectares was producing grains, root crops, and marsh hay. Once the land was drained, the cost of producing hay was low, Tantramar hay was sold to lumber camps, exploration, and mining in Atlantic Canada and stables as far away as Boston. In the 1930s there were more than 400 post-and-beam hay barns on the marshes, for hay storage. Today there are fewer than 30. The price of hay was 28$ per ton in 1920, but as horses were replaced by cars and as manufacturing moved west, the hay price fell to 7$ a ton in 1938. The marshes then became pasture, and as their agricultural profitability declined the Canadian Wildlife Service and Ducks Unlimited helped to return the marshes to a more natural state.
