  • Annual Report 2017 Canada’S Landscapes Have a Wealth of Stories to Tell
    hallowed grounConserving Canada’s natural historyd annual report 2017 Canada’s landscapes have a wealth of stories to tell. Stories of history and culture. Stories of sacred traditions and pioneering spirits. From coast to coast to coast, the nation’s land and water have inspired countless tales of exploration and discovery, progress and change. Since 1938, Ducks Unlimited Canada has been helping conserve the hallowed ground where history is made. It’s a responsibility we’re committed to – now and always. Happy 150th anniversary, Canada. Ducks Unlimited Canada (DUC) is proud to be part of a nation committed to conserving the iconic landscapes of the true north strong and free. It’s in our nature. From shallow wetlands to dense forests, grasslands, salt marshes and coastal estuaries,Canada’s wetlands are part of an environmental legacy DUC is creating thanks to the support of people from across the country. But these wetlands are more than just a backdrop. They are essential elements of our lives. Water. Wildlife. Recreation. Protection against extreme weather and support for healthy communities. Wetlands are engrained in Canada’s natural history. DUC has been working for 79 of Canada’s 150 confederated years. Partnerships with peoples from all cultures and backgrounds are the roots of our success. Respect for the unique ways that wetlands and wildlife connect us all is what drives our ongoing quest for a better, healthier world. Together, we’re continuing to define what it means to be Canadian – and what it means to be a conservationist. Great Bear Lake wetland Great Bear Lake is a part of the Yamoria legends — ancient Dene stories about giant heroes, animals and living landscapes.

  • Fort Beausejour National Historic Park Aulac, New Brunswick Canada
    Fort Beausejour National Historic Park Aulac, New Brunswick Canada Issued under the authority of the HONOURABLE ARTHUR LAING, P.C., M.P., B.S.A. Minister of Indian Affairs and Northern Development Original Earthen Bastion of French Period Fort Beausejour National Historic Park Aulac, New Brunswick At the middle of the 18th century the dividing line between French and British influence in Acadia lay along the Missaguash River, one of the four rivers that drain the southern slope of the Isthmus of Chignecto. In 1710 New England militiamen and British regulars had captured the French Port Royal, thus in one engagement effecting the conquest of the Nova Scotia main- land. The Treaty of Utrecht, concluded three years later, formally transferred Acadia to Great Britain. But what was Acadia? The British hopefully believed parts of what is now New Brunswick were included. The French, confident that they would soon win back the Nova Scotia mainland, could not consider such a broad definition of the geographical limits of Acadia. They were determined to hold as much ground as they could. Time seemed to be in their favor. Against the weak and ill-disciplined garrison at Annapolis Royal and the few detachments occupying isolated posts in the peninsula, the French could send Indian raiding parties. While the British struggled against the harassments of the Indians, the population of Acadia—over­ whelmingly French—could be provoked to at least passive resistance against their alien conquerors. French power preserved at the Fortress of Louisbourg on Cape Breton Island and at the settlements of New France along the St.

  • New Brunswick Eastern Habitat Joint Venture Five Year Implementation Plan for the North American Waterfowl Management Plan
    New Brunswick Eastern Habitat Joint Venture Five Year Implementation Plan for the North American Waterfowl Management Plan New Brunswick Eastern Habitat Joint Venture December 14 2007 Executive Summary The New Brunswick Eastern Habitat Joint Venture (NB-EHJV) was established in 1989 to implement the North American Waterfowl Management Plan (NAWMP) in New Brunswick through a partnership of federal, provincial and regional conservation organizations. The NB-EHJV Five Year Implementation Plan to be known as the Plan is an update of the 1989 – 2004 NB Eastern Habitat Joint Venture Implementation Plan. The Plan outlines the current status of wetland habitats and waterfowl populations in New Brunswick and presents waterfowl population goals and habitat conservation targets for the next five years. The Plan is a blueprint for the conservation of important breeding, staging and wintering waterfowl habitat in New Brunswick. It describes the habitat conservation program the NB- EHJV partnership will employ to achieve the waterfowl population objectives, the methods for program assessment and the resource needs. Though this Plan may benefit other bird species, it does not explicitly address the objectives for the other bird Pillars of the North American Bird Conservation Initiative (NABCI). The Plan will address 15% (1,105 IBP) of the 7,600 IBP population deficit for dabbling ducks (American black duck, Mallard, green-winged teal, ring-necked duck) in NB through the enhancement or restoration of 1,380 hectares of wetlands and the active management of 13,901 hectares of wetlands to optimum waterfowl brood rearing conditions. A nest box program will be used to increase wood duck and common goldeneye.

  • Desplanque & Mossman
    66 Desplanque & Mossman large surface area. It was on Jean Baptiste day, 24 June, 1604, that the fi rst Europeans in the region, Pierre de Gua, the Sieur de Monts, a Huguenot merchant, and Samuel de Champlain, Royal Geographer, discovered the mouth of one of the largest rivers on the eastern seaboard of North America. These pio- neers and others who came later described its mouth in their logbooks and reports. According to the Jesuit missionary Pierre Baird (1611), “The entrance to this river is very narrow and dangerous, for a ship has to pass between two rocks, where the current is tossed from one side to the other, fl ashing between them as an arrow. Upstream from the rocks is a frightful and horrible precipice, and if you do not pass it at the proper mo- ment, and when the water is smoothly heaped up, of a hundred thousand barques not an atom would escape, but men and goods would all be lost.” (Raymond 1910). Doubtless Baird was well aware of the Indian legend concerning the hazardous entrance to Saint John Harbour. Here the Indian cultural hero Glooscap is said to have created the Reversing Falls when he destroyed a large beaver dam built across the river’s mouth. (The remains of Glooscap’s beaver dam support a popular restaurant!) The natural feature responsible for the legend lies at the downstream end of a 4 km long, tortuous river section. At Indiantown, water surface levels can vary between 0.3 m above Geodetic Survey of Canada Datum (GD) during periods of small river discharges, to 5.2 m above GD during extremely large runoffs.
