Midwestern Canadian Shield Forests
The Midwestern Canadian Shield forests ecoregion, in the Taiga and Boreal forests Biome, are of northern Canada. Setting This is an area of rolling hills with lakes both small and large, wetlands, and rocky outcrops on the Canadian Shield in northern Saskatchewan, north-central Manitoba (north and east of Lake Winnipeg) and Northwestern Ontario. Specific areas include the Athabasca Sand Dunes, and many lakes such as Cree Lake, Upper Foster Lake and Reindeer Lake in Saskatchewan. The area has a cold climate, very cold in winter although the hills around Lac Seul are warmer and wetter than most of the ecoregion, while the Athabasca Plain and the uplands above the Churchill River and Hayes River are cooler. There are patches of permafrost throughout Flora Much of the landscape, including the Athabasca Plain, is the boreal forest that covers so much of Canada at this latitude, consisting of black spruce (''Picea mariana''), jack pine (''Pinus banksiana''), quaking aspen (''Populu ...

Pisew Falls Provincial Park
Pisew Falls Provincial Park is a List of provincial parks in Manitoba, provincial heritage park in the southwestern portion of Mystery Lake, Manitoba, Mystery Lake, Manitoba, Canada. Located near Kwasitchewan Falls, Manitoba's highest waterfall, Pisew Falls stands at the approximate midpoint between the small community of Wabowden, Manitoba, Wabowden and the much larger industrial and service centre of Thompson, Manitoba, Thompson. It is also located approximately north of Winnipeg, Manitoba, Winnipeg, and from Manitoba Highway 6, Highway 6. The name ''Pisew'' is translated from words for "lynx" in the local Cree language, named for the sound of the hissing water which bears a resemblance to the sounds made by the wild lynx. Pisew Falls' creation was due to the intensive geological activity in the area hundreds of thousands of years ago, when violent tectonic effects caused the creation of first a Geologic fault, fault, and then an upheaval of the southern side of the fault-li ...

Northwestern Ontario
Northwestern Ontario is a secondary region of Northern Ontario in the Canadian province of Ontario which lies north and west of Lake Superior and west of Hudson Bay and James Bay. It includes most of subarctic Ontario. Its western boundary is the Canadian province of Manitoba, which disputed Ontario's claim to the western part of the region. Ontario's right to Northwestern Ontario was determined by the Judicial Committee of the Privy Council in 1884ONTARIO-MANITOBA BOUNDARY CASE and confirmed by the Canada (Ontario Boundary) Act, 1889, of the Parliament of the United Kingdom. In 1912, the Parliament of Canada by the ''Ontario Boundaries Extension Act'' gave jurisdiction over the District of Patricia to Ontario, thereby extending the northern boundary of the province to Hudson Bay. For some purposes, Northwestern Ontario and Northeastern Ontario are treated as separate regions, while for other purposes they are grouped together as Northern Ontario.

Balsam Poplar
''Populus balsamifera'', commonly called balsam poplar, bam, bamtree, eastern balsam-poplar, hackmatack, tacamahac poplar, tacamahaca, is a tree species in the balsam poplar species group in the poplar genus, ''Populus.'' The genus name ''Populus'' is from the Latin for poplar, and the specific epithet ''balsamifera'' from Latin for "balsam-bearing". ''Populus balsamifera'' is the northernmost North American hardwood, growing transcontinentally on boreal and montane upland and flood plain sites, and attaining its best development on flood plains. It is a hardy, fast-growing tree which is generally short lived, but some trees as old as 200 years have been found. The tree is known for its strong, sweet fragrance, which emanates from its sticky, resinous buds. The smell has been compared to that of the balsam fir tree. Taxonomy The black cottonwood, ''Populus trichocarpa'', is sometimes considered a subspecies of ''P. balsamifera'' and may lend its common name to this species, alt ...

Betula Papyrifera
''Betula papyrifera'' (paper birch, also known as (American) white birch and canoe birch) is a short-lived species of birch native to northern North America. Paper birch is named for the tree's thin white bark, which often peels in paper like layers from the trunk. Paper birch is often one of the first species to colonize a burned area within the northern latitudes, and is an important species for moose browsing. The wood is often used for pulpwood and firewood. Description It is a medium-sized deciduous tree typically reaching tall, and exceptionally to with a trunk up to in diameter. Within forests, it often grows with a single trunk but when grown as a landscape tree it may develop multiple trunks or branch close to the ground. Paper birch is a typically short-lived species. It handles heat and humidity poorly and may live only 30 years in zones six and up, while trees in colder-climate regions can grow for more than 100 years. ''B. papyrifera'' will grow in many so ...

Populus Tremuloides
''Populus tremuloides'' is a deciduous tree native to cooler areas of North America, one of several species referred to by the common name aspen. It is commonly called quaking aspen, trembling aspen, American aspen, mountain or golden aspen, trembling poplar, white poplar, and popple, as well as others. The trees have tall trunks, up to 25 meters (82 feet) tall, with smooth pale bark, scarred with black. The glossy green leaves, dull beneath, become golden to yellow, rarely red, in autumn. The species often propagates through its roots to form large clonal groves originating from a shared root system. These roots are not rhizomes, as new growth develops from adventitious buds on the parent root system (the ortet). ''Populus tremuloides'' is the most widely distributed tree in North America, being found from Canada to central Mexico. It is the defining species of the aspen parkland biome in the Prairie Provinces of Canada and extreme northwest Minnesota. Description Quaking a ...

Jack Pine
Jack pine (''Pinus banksiana'') is an eastern North American pine. Its native range in Canada is east of the Rocky Mountains from the Mackenzie River in the Northwest Territories to Cape Breton Island in Nova Scotia, and the north-central and northeast of the United States from Minnesota to Maine, with the southernmost part of the range just into northwest Indiana and northwest Pennsylvania. It is also known as grey pine and scrub pine. In the far west of its range, ''Pinus banksiana'' hybridizes readily with the closely related lodgepole pine (''Pinus contorta''). The species epithet ''banksiana'' is after the English botanist Sir Joseph Banks. Description ''Pinus banksiana'' ranges from in height. Some jack pines are shrub-sized, due to poor growing conditions. They do not usually grow perfectly straight, resulting in an irregular shape similar to pitch pine (''Pinus rigida''). This pine often forms pure stands on sandy or rocky soil. It is fire-adapted to stand- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Picea Mariana
''Picea mariana'', the black spruce, is a North American species of spruce tree in the pine family. It is widespread across Canada, found in all 10 provinces and all 3 territories. It is the official tree of the province of Newfoundland and Labrador and is that province's most numerous tree. The range of the black spruce extends into northern parts of the United States: in Alaska, the Great Lakes region, and the upper Northeast. It is a frequent part of the biome known as taiga or boreal forest.. The Latin specific epithet ''mariana'' means “of the Virgin Mary”. Description ''P. mariana'' is a slow-growing, small upright evergreen coniferous tree (rarely a shrub), having a straight trunk with little taper, a scruffy habit, and a narrow, pointed crown of short, compact, drooping branches with upturned tips. Through much of its range it averages tall with a trunk diameter at maturity, though occasional specimens can reach tall and diameter. The bark is thin, scaly, and ...

Permafrost
Permafrost is ground that continuously remains below 0 °C (32 °F) for two or more years, located on land or under the ocean. Most common in the Northern Hemisphere, around 15% of the Northern Hemisphere or 11% of the global surface is underlain by permafrost, with the total area of around 18 million km2. This includes substantial areas of Alaska, Greenland, Canada and Siberia. It can also be located on mountaintops in the Southern Hemisphere and beneath ice-free areas in the Antarctic. Permafrost does not have to be the first layer that is on the ground. It can be from an inch to several miles deep under the Earth's surface. It frequently occurs in ground ice, but it can also be present in non-porous bedrock. Permafrost is formed from ice holding various types of soil, sand, and rock in combination. Permafrost contains large amounts of biomass and decomposed biomass that has been stored as methane and carbon dioxide, making tundra soil a carbon sink. As global war ...

Hayes River
The Hayes River is a river in Northern Manitoba, Canada, that flows from Molson Lake to Hudson Bay at York Factory. It was historically an important river in the development of Canada and is now a Canadian Heritage River and the longest naturally flowing river in Manitoba. Course The river begins at the northern end of Molson Lake (about northeast of the northern tip of Lake Winnipeg) at an elevation of and flows northeastward. Near Molson Lake, the Echimamish River connects with the Hayes. The Echimamish is a river bifurcation that connects the Hayes to the Nelson River, which flows out of Lake Winnipeg. This river connector was used by the voyageurs to travel from York Factory on Hudson Bay, up the Hayes and across to the Nelson and on to Norway House at the north end of Lake Winnipeg. Northeast of Robinson Lake is Robinson Falls and the mile-long Robinson portage which was the longest portage between Hudson Bay and Edmonton. Somewhere in this area is Hill Gates, a mile-l ...

Churchill River (Hudson Bay)
The Churchill River () is a major river in Alberta, Saskatchewan and Manitoba, Canada. From the head of the Churchill Lake it is long. It was named after John Churchill, 1st Duke of Marlborough and governor of the Hudson's Bay Company from 1685 to 1691. The Cree name for the river is ''Missinipi'', meaning "big waters". The Denesuline name for the river is ''des nëdhë́'', meaning "Great River". The river is located entirely within the Canadian Shield. The drainage basin includes a number of lakes in Central-East Alberta which flow into a series of lakes in Saskatchewan and Manitoba. The main tributary, the Beaver River, joins at Lac Île-à-la-Crosse. Nistowiak Falls—the tallest falls in Saskatchewan—are on the Rapid River, which flows north, out of Lac la Ronge into Nistowiak Lake on the Churchill just north of La Ronge. A large amount of flow of the Churchill River after Manitoba–Saskatchewan border comes from the Reindeer River, which flows from Wollaston ...

Lac Seul
Lac Seul is a large, crescent shaped reservoir in Kenora District, northwestern Ontario, Canada. It is approximately long. It has a maximum (regulated) depth of 47.2 m, with a surface elevation of 357 m above sea level. Its level is raised in the summer and then drawn down in the winter months to reach points of as low as 16 feet below the maximum level. It is the second largest body of water entirely within the province of Ontario (Lake Nipigon being first). The lake consists of open water bays, narrow channels, and islands. It is a relatively shallow lake with many rock shoals. This provides a good habitat for walleye (also known as "yellow pickerel") and northern pike as well as yellow perch. During the Lac Seul project of 1968-1972 no muskelunge were noted in the catches of research nets set over those years. Significant numbers of whitefish, tullibee, burbot and cisco were noted as well although they infrequently were noted in the sport fishery. Lac Seul is noted f ...

Reindeer Lake
Reindeer Lake is a lake in western Canada located on the border between north-eastern Saskatchewan and north-western Manitoba, with the majority in Saskatchewan. The name of the lake appears to be a translation of the Algonquian name. It is the 24th largest lake in the world by area, as well as being the second-largest lake in Saskatchewan and the ninth largest in Canada. 8% of the lake lies in Manitoba and 92% of lake in Saskatchewan. Geography Reindeer Lake has a heavily indented shoreline and contains numerous small islands. On its eastern shore is the community of Kinoosao, at its northern end Brochet, Manitoba; and at its southern end, Southend, Saskatchewan. It drains mainly to the south, via the Reindeer River and a controlled weir, to the Churchill River and then east to Hudson Bay. Water flow out of the lake is regulated by the Whitesand Dam. Deep Bay, located at the south end of the lake and measuring about wide and deep, is the site of a large meteorite impa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
