birds of the Peace-Athabasca Delta and of the Lake Athabasca region by E. O. HГ¶hn Download PDF EPUB FB2
No other waterfowl staging area in Canada is as important as the delta, which harbors species of birds. If the drying of the Peace-Athabasca Delta continues, it could threaten one of North America’s most vibrant ecosystems, home to as many as a million birds; a commercial fishery that relies on walleye, pike, and lake whitefish; the world.
With species of birds, the Peace-Athabasca Delta is a birdwatcher’s delight. The marshes, lakes and mudflats of the delta provide critical breeding, moulting and staging habitat for waterfowl.
Up to a million ducks, geese and swans, from all four North American flyways, pass through the delta in the spring and fall. As one of the largest inland freshwater deltas in the world, the Peace-Athabasca Delta ( km 2) is a complex and dynamic ecosystem of rivers, lakes, channels, marshes, and grasslands.
Its lush wetlands provide habitat for 45 species of mammals. The Peace-Athabasca Delta is the largest boreal delta in the world, and the varied habitats found in the delta—including shallow lakes, mud flats, fens, meadows, and forest, for example—support at least species of birds, 44 species of mammals, 18 species of fish, and thousands of species of insects and invertebrates (Wetlands.
Lake Athabasca (/ ˌ æ θ ə ˈ b æ s k ə /; French: lac Athabasca; from Woods Cree: aðapaskāw, "[where] there are plants one after another") is located in the northwest corner of Saskatchewan and the northeast corner of Alberta between 58° and 60° lake is Coordinates: 59°16′N °27′W /.
Lake Athabasca and the Peace-Athabasca Delta are perhaps the most ecologically rich areas of the Athabasca River basin.
The unique geographical features and ecological importance of this area are internationally recognized, and portions of the delta and lake basin now lie within national and provincial protected areas. "In the delta, water is boss, change is the only constant, and creation and destruction exist side by side." The Peace-Athabasca Delta in northern Alberta is a globally significant wetland that lies within one of the largest unfragmented landscapes in North America.
The combined Peace-Athabasca Basin (including the area draining directly into Lake Athabasca) is the largest watershed in Alberta, coveringkm 2 or 52% of the province. The Peace and the Athabasca are two of the three largest rivers in Alberta; the Slave River, formed by their confluence, is the province's largest.
Lake Athabasca is located in northeastern Alberta and northwestern Saskatchewan, at the edge of the Precambrian an area of 7, km 2 and a 2, km shoreline, it is the eighth-largest lake in Canada. It has an elevation of m, a. The Peace–Athabasca Delta (PAD) ecosystem is a delta complex located at the confluence of the Peace and Athabasca River Deltas and several smaller deltas at the west end of Lake Athabasca.
Lake Athabasca and the PAD are located on the rim of the Precambrian Shield at the interface of Precambrian mostly igneous rocks to the east and Paleozoic Author: Kevin Timoney, Peter Lee.
The Athabasca River travels 1, km ( mi) before draining into the Peace-Athabasca Delta near Lake Athabasca south of Fort Chipewyan. From there, its waters flow north as Rivière des Rochers, then joining the Peace River to form the Slave River that empties into Great Slave Lake and discharges through the Mackenzie River system into the Mouth: Lake Athabasca.
The Athabasca River headwaters are located on the eastern slopes of the Rocky Mountains, at the Columbia flows northeast through the steep mountainous region of Jasper National Park and past the foothills region where it is joined by the Berland and McLeod Rivers, before entering a boreal forest region.
Between Whitecourt and Athabasca, the Athabasca River is. Alberta’s largest IBA, the Peace-Athabasca Delta is a RAMSAR Wetland of Global Signifi-cance and is for the most part located within Wood Buffalo National Park, itself a UNESCO World Heritage Site.
This large inland delta is a complex of lakes and wetlands that interact with the Peace, Athabasca and Slave rivers and their Size: 9MB. The Peace-Athabasca Delta began to form ab years ago and it now forms a composite, inland delta of the bird's-foot type. The Peace, Athabasca and Birch Deltas occupy an area of square miles and, at present, extend their total area 1 square mile every 13 years.
The Peace-Athabasca Delta in northern Alberta is one of the largest freshwater deltas (>4, sq. km) in the world. The highly complex ecosystem of lakes, wetlands and meadows supports a Author: Jeff Shatford.
The Peace-Athabasca Delta Ecosystem Management Plan (implemented in ) is undergoing a cooperative study between Parks Canada, the Alberta government and local native organizations. Although the delta's size, isolation, and wilderness character have provided protection for many of its ecological features, it is being affected by external.

Notes: Prepared for Peace-Athabasca Delta. The mean annual discharges in cubic decameters (dam3 = cubic meters) at points along the river are: 2, dam³ at Jasper; 13, dam³ at Athabasca;dam³ at Fort McMurray.
The confluence of the Peace and Athabasca Rivers with Lake Athabasca in the north forms a vast wetland called the Peace-Athabasca delta.
Lakes of the Peace-Athabasca Delta: Controls on nutrients, chemistry, phytoplankton, epiphyton and deposition of polycyclic aromatic compounds (PACs) by Johan André Wiklund A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Biology Waterloo, Ontario, Canada, The Peace–Athabasca Delta in northern Alberta, Canada, is a dynamic wetland ecosystem.
Climatic, hydrologic, biological, and historical data are synthesized to elucidate how the ecosystem has. Mercury levels were measured in colonial waterbird eggs collected from two sites in northern Alberta and one site in southern Alberta, Canada.
Northern sites in the Peace-Athabasca Delta and Lake Athabasca were located in receiving waters of the Athabasca River which drains the oil sands industrial region north of Fort McMurray, by: Peace-Athabasca Delta. File Attachment: info-sheet-peace-athabasca-delta-febpdf.

John Consultation Office. Inthe Peace-Athabasca Delta was recognized by the Ramsar Convention as a “Wetland of International Significance,” alongside more than 2, waterways around the world. It was deemed significant for its ability to support hundreds of bird species, some of which are species at risk, and a healthy bison population.

As a result, Site C will be able to generate about 35 per cent of the energy produced at the W.A.C.

The Athabasca River Basin iskm 2 in area and accounts for approximately 22% of Alberta's landmass (Gummer et al., ).It is fed by ten smaller watersheds or sub-watersheds that flow into the Athabasca River. The majority of the watershed is within the province of Alberta ().The headwaters of the basin originate in the Rocky Mountains and flows northeast for > Cited by: 6.
Athabasca River, provide habitat for 31 of Alberta’s 59 species of fish, including walleye, lake whitefish, northern pike, and burbot. The Athabasca converges with the Peace and Birch Rivers at the western end of Lake Athabasca to form the Peace-Athabasca Delta, a 6,square-kilometre (km2) wetland complex of global Size: 2MB.
Peace-Athabasca Delta-As the largest freshwater delta in the world, the Peace-Athabasca Delta Natural Subregion is composed mostly of the delta itself, however, there are areas that include the uppermost region of the Slave River and the lowermost portion of the Peace River.
Residing south and west of Kaje Athabasca, this Natural Subregion is.The Peace is an important fishery and recreational river and the project may further impact the Peace-Athabasca Delta in Wood Buffalo National Park. The project may also interfere with future efforts to enable flooding of the delta, which has already been seriously affected by the Bennett Dam on the Peace in B.C.Along the banks where the great Athabasca River makes its final hard turn north toward the delta, the snow that day fell in a formidable blizzard.
It stormed for three days, and nearly half a metre blanketed the river banks and the forests of pine and spruce and the lakes and ponds strewn across the landscape east and west of the ed on: Novem
