Tantramar Marshes

The boundaries of Tintamarre National Wildlife Area were proposed in 1966 for the National Habitat Protection Program, through the government of Canada. The land was acquired by the Canadian Government up until the mid 1970s and officially declared a National Wildlife Area in 1978. Two additional units to the area are being proposed but unofficial, surrounding Hog Lake and Towers Goose Lake. Tintamarre Marsh is a breeding area for several types of waterfowl, and home to numerous plants and animals. Other threats include invasive species outcompeting native wildlife and climate change. == Natural environment ==

Wildlife The Tantramar Marsh is a saltwater tidal marsh comprising many interconnecting waterways. Much of the area is below sea level, but instances of flooding are prevented by the soft ground and plant life which withhold water and filter out toxins. This mix of fresh and saltwater creates unique ecosystems for many species, mostly birds and fish. The marshes are home to species such as the northern harrier (Circus hudsonius), American bittern (Botaurus lentiginosus), sora (Porzana carolina), muskrat (Ondatra zibethicus), and maritime shrew (Sorex maritimensis), all of which are vital to the marsh's ecological systems. Keystone species The presence of these keystone species ensures the continued vitality of the marshes and the ecosystems that they support. The northern harrier is a bird of prey, feeding on small rodents which eat grass seeds and the eggs and young of other birds. The American bittern and Sora are elusive waterfowl which are highly sensitive to changes in their environment, so they have been classified as indicator species. The muskrat is a rat-sized rodent which has evolved to become semi-aquatic. The maritime shrew is another rodent, slightly smaller than the muskrat, which responds to increasing numbers of insects and goes on a feasting spree. Species at risk The marshes are also home to numerous species at risk as designated under the Species at Risk Act (SARA). The American eel (Anguilla rostrata) also makes its home here as it can breed in the Gulf's salt water and migrate the short distance to fresh river water in the marshes. The Atlantic salmon (Salmo salar) also enjoys the mix of salt and fresh water – the eggs are laid in the clean waters of rivers and streams where the young can feed and grow safely. Once large enough, they migrate to the salt waters of the gulf until they are ready to return to the marsh to breed. Plant life With its ability to thrive in exposed environments with low-lying landscapes, Spartina dominates the plant life in the Tantramar marshes. The spartina is essential in stabilizing clay, sand, silt, and muck of the saltmarshes. Saltwater cordgrass (Spartina alternifolia) grows closest to water in the low marshlands along the boundaries of the tidal rivers and are flooded daily with salt water (about 12-15%). The rise in temperature is creating new environments in which invasive species and diseases can survive while native species struggle to adapt. Rising sea levels increase the threat of flooding too much for the marshes to be able to regulate. Water from flooding via dyke failure or from increased and more intense storms due to climate change will also lead to accelerated erosion, draining the wetland of many important nutrients. == Uses of the marsh ==

For a full account of human activity on the marshes, see the History of Sackville. Historical uses The Mi'kmaq are the Indigenous peoples of Tantramar marshes and surrounding areas, they have many traditional uses for the resources in this area. The marsh was used for harvesting of different kinds of plants, wildfowl, small mammals and fish as means of food. Before the arrival of Europeans, well-travelled portage routes connected the Bay of Fundy with the Northumberland Strait as the marsh was used seasonally. Migrating from Port Royal in around 1671, Acadians established a village in the area (which they called Beaubassin). They founded a number of scattered settlements on higher ground, and created dry farmland using polderisation, by building the dykes and sluices which converted the salt marshes to fields and pastures. Following the Battle of Fort Beauséjour which marked 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, drying the land in order to plant crops for agricultural practices. During the 19th century the land use in and around the Tantramar region changed, land ownership became consolidated and 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 turned into polders, the cost of producing hay was low. Inexpensive Tantramar hay was then 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. After 2010 fears emerged that rising sea levels and deterioration of 18th-century hand-built dykes and sluices threatened to flood the Tantramar Marshes and make Nova Scotia into an island separate from the North American mainland.In 1945 Radio Canada International opened a radio transmitter and the site proved to be one of the best shortwave transmitting locations in the world. Shortwave broadcasting ended in 2012 and transmitting towers have since been removed. In 2017, the CBC announced that the site had been sold to a non-profit consortium of New Brunswick Mi'kmaq bands known as Mi'gmawe'l Tplu'taqnn. The intended use of the property was not disclosed. Present uses The declaration of the Tantramar Marshes as a protected area resulted in many restrictions being imposed with how the land and water surrounding it can be accessed and used. Visitors are given access to the protected area for things like leisure activities, which include swimming, having group events and meals, using the trails for hikes, boating, skiing/snowboarding and skating. Sport hunting of specific animals is allowed, as long as the required permits have been attained and regulations are followed. Fishing is also allowed but limits are imposed to avoid overfishing, a permit is also required for sport fishing. Any access to the Tintamarre National Wildlife Area, and with regards to all the above-mentioned uses of the park, are only permitted from sunrise to sunset. Use outside of those times is against the Law. ==See also==
