Eastern Canadian Shield Taiga
The Eastern Canadian Shield taiga is an ecoregion of Canada as defined by the World Wildlife Fund (WWF) categorization system. Setting Located in northeastern Canada, this ecoregion covers a large part of northern Quebec and most of Labrador, reaching from Hudson Bay and James Bay in the west, across to Ungava Bay and east to the Atlantic Ocean coast of Labrador. This is a taiga ecoregion and therefore stops at the treeline, beyond which is tundra. This is a rugged rocky landscape including an area fjords on the Atlantic coast of Labrador. The hills and plateaus are dotted with many lakes and string bogs, and patches of tundra on the Mealy Mountains and elsewhere. This is a cold part of the world with average annual temperatures ranging from −6°C in Hudson Bay to 1°C on the Labrador coast. Flora The dominant trees of the taiga are black spruce (''Picea mariana'') and tamarack (''Larix laricina''), mixed with smaller numbers of white spruce (''Picea glauca''), dwarf birches, ...

Caniapiscau Reservoir
The Caniapiscau Reservoir () is a reservoir on the upper Caniapiscau River in the Côte-Nord administrative region of the Canadian province of Quebec. It is the largest body of water in Quebec and the second largest reservoir in Canada. The Caniapiscau Reservoir, formed by two dams and forty-three dikes, is the largest reservoir in surface area of the James Bay Project. As headpond, it feeds the power plants of the La Grande complex in the winter and provides up to 35% of their production. Its total catchment area is about . The reservoir was named after Lake Caniapiscau that was flooded during the formation of the reservoir. The name is an adaptation of the Cree or Innu toponym ''kâ-neyâpiskâw'', which means "rocky point". Albert Peter Low had noted in 1895 that "a high rocky headland jutts into the lake." He probably referred to the northwest facing peninsula that gives the reservoir the shape of an arc as we current know it. The Caniapiscau Reservoir is accessible by b ...

Ungava Bay
Ungava Bay (french: baie d'Ungava, ; iu, ᐅᖓᕙ ᑲᖏᖅᓗᒃ/) is a bay in northeastern Canada separating Nunavik (far northern Quebec) from Baffin Island. Although not geographically apparent, it is considered to be a marginal sea of the Arctic Ocean for climatic reasons. The bay is roughly oval-shaped, about at its widest point and about in length; it has an area of approximately . It is generally fairly shallow, under , though at its border with the Atlantic Ocean depths of almost are reached. Geography Although it is quite close to the open Atlantic (separated only by Hudson Strait), Ungava Bay is part of the Arctic Ocean. Ungava Bay is separated from Hudson Bay by the Ungava Peninsula. Akpatok Island is largest of the many islands in Ungava Bay. Bathymetric studies suggest that Ungava Bay may be the remnant of an impact crater (age unknown) approximately in diameter. The southwestern corner of Ungava Bay vies with the Bay of Fundy for the highest tidal range in t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyperaceae
The Cyperaceae are a family of graminoid (grass-like), monocotyledonous flowering plants known as sedges. The family is large, with some 5,500 known species described in about 90 genera, the largest being the "true sedges" genus ''Carex'' with over 2,000 species. These species are widely distributed, with the centers of diversity for the group occurring in tropical Asia and tropical South America. While sedges may be found growing in almost all environments, many are associated with wetlands, or with poor soils. Ecological communities dominated by sedges are known as sedgelands or sedge meadows. Some species superficially resemble the closely related rushes and the more distantly related grasses. Features distinguishing members of the sedge family from grasses or rushes are stems with triangular cross-sections (with occasional exceptions, a notable example being the tule which has a round cross-section) and leaves that are spirally arranged in three ranks. In comparison, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower.

Lauraceae
Lauraceae, or the laurels, is a plant family that includes the true laurel and its closest relatives. This family comprises about 2850 known species in about 45 genera worldwide (Christenhusz & Byng 2016 ). They are dicotyledons, and occur mainly in warm temperate and tropical regions, especially Southeast Asia and South America. Many are aromatic evergreen trees or shrubs, but some, such as ''Sassafras'', are deciduous, or include both deciduous and evergreen trees and shrubs, especially in tropical and temperate climates. The genus ''Cassytha'' is unique in the Lauraceae in that its members are parasitic vines. Most laurels are highly-poisonous. Overview The family has a worldwide distribution in tropical and warm climates. The Lauraceae are important components of tropical forests ranging from low-lying to montane. In several forested regions, Lauraceae are among the top five families in terms of the number of species present. The Lauraceae give their name to habitats know ...

String Bog
A string bog or string mire is a bog consisting of slightly elevated ridges and islands, with woody plants, alternating with flat, wet sedge mat areas. String bogs occur on slightly sloping surfaces, with the ridges at right angles to the direction of water flow. They are an example of patterned vegetation. String bogs are also known as aapa moors or aapa mires (from Finnish ''aapasuo'') or Strangmoor (from the German). A string bog has a pattern of narrow (2–3m wide), low (less than 1m high) ridges oriented at right angles to the direction of drainage with wet depressions or pools occurring between the ridges. The water and peat are very low in nutrients because the water has been derived from other ombrotrophic wetlands, which receive all of their water and nutrients from precipitation, rather than from streams or springs. The peat thickness is greater than 1m. String bogs are features associated with periglacial climates, where the temperature results in long periods of s ...
