Terms in this set (6)Arctic Tundra. - found in the northern most parts of Canada. ... Boreal Forest. - largest vegetative region in Canada. ... Temperature Rainforest. - costal regions have a mild climate with abundant precipitation. ... Short Grass Prairie. - the growing season is warm and dry. ... Long Grass Prairie. ... Mixed Forest.
Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least.
Tundra is predominant in: Canada's northern mainland - the terrain north of the arboreal taiga belt, east and west of Hudson Bay. the islands of the Arctic Archipelago - bordered by the Beaufort Sea, Hudson Bay and Baffin Bay....Canadian Arctic TundraHabitat lossArctic fox, polar bear, caribou%15 more rows
There are eight major terrestrial biomes: tropical rainforests, savannas, deserts, chaparral, temperate grasslands, temperate forests, taiga (boreal forests), and Arctic tundra.
Tropical forestsTropical forests have the highest biodiversity and primary productivity of any of the terrestrial biomes.
Often thought of as a barren and somewhat rocky biome, the tundra surrounds the pole and is the dominant biome in the Arctic and Subarctic regions. In Canada, the Arctic tundra can be found in Yukon, the Northwest Territories, Nunavut, northeastern Manitoba, northern Ontario, northern Quebec and northern Labrador.
The deciduous forests are more diverse than the boreal forests as relatively few species of plants and animals have adapted to live in the relatively...
Biomes of Canada. The major biomes in Canada are Tundra, Boreal Forest, Mountain Forest , Grassland, and Deciduous Forest. Tundra is the dominant land type of the Arctic and subarctic regions. Moutain forests are the highest evelation of the biomes in Canada. Grassland biome in Canada is one of the smallest is one of the smallest biomes in size.

They may refer to either land or water, and can vary in size. The term “natural region” is often used interchangeably with the word “ecozone.”. Canada has 20 natural regions (15 terrestrial and five marine).
The coastal mountain ranges are the region’s most striking feature. They are part of the Pacific Ring of Fire mountains — a semi-circle of mountainous terrain set around the Pacific Ocean and known to be prone to volcanic eruptions and earthquakes. The coastal mountains typically rise sharply from the fjords and coastlines of the Pacific Ocean and climb along steep and forested slopes to glacier-covered peaks. Mount Waddington is among the highest peaks. The main materials that cover the land surfaces tend to follow an orderly pattern. The summits comprise bare rock and ice fields, whereas the mountain slopes are mantled by colluvial debris, and the lower foot slopes and valleys have morainal and some fluvial deposits. The soils which have developed on the slopes and valleys are productive forest soils (like the Podzols). One major valley and flood plain emerges along the coast, called the Fraser River valley .
Like the Taiga Shield ecozone to the north, this ecozone shares many of the same landform features —hilly terrain, many rock outcrops, moraine and fluvial deposits of variable depths. The depressions and natural fracture patterns in the Canadian Shield bedrock are littered with countless lakes, ponds, wetlands, rivers and streams. Significant parts of the watersheds for the Churchill, Abitibi and Nelson rivers are contained in this ecozone.
Annual precipitation ranges from 800 mm in the north to 2,000 mm in the south. However, in localized areas like the Okanagan Valley , the precipitation can be well below 500 mm where the local climate is hot and desert-like.
Less than 10 per cent is now forested and much of this comprises isolated pockets. The mixed forest area included species such as eastern white pine, eastern hemlock, yellow birch, red pine, sugar maple, red oak and basswood. Deciduous trees are more common in the southerly portion of this ecozone. The remnants of the deciduous Carolinian forest region are home to unique species. Unlike conifers, deciduous trees lose their leaves in the fall. This produces the splendid show of colour familiar to most Canadians. The warm climate and the extensive amount of soils supports more species of trees than any other ecozone of Canada.
The Arctic Cordillera ecozone contains the only major mountainous region of Canada outside the western mountain system known as the Rockies . It provides an eastern spine to the Arctic, occupying most of Ellesmere and Axel Heiberg Islands, as well as the eastern edges of Devon, Bylot and Baffin Islands, and parts of northern Labrador .
The topography of the Lowlands is the result of weathering and erosion by rivers of the nearby flat-lying early sedimentary rock (photo by Thomas Kitchin). Very little of this ecozone is in its natural state. Less than 18% of the short-grass remains and only 1% of the tall-grass (artwork by Autumn Downey).
POLAR / ALPINE: temperature too low and substrate too unstable to support permanent vegetation.
A. TUNDRA: treeless low (less than 1 m) vegetation with short perennials, water frozen. Typical plants include sedges, lichens, mosses, grasses, and dwarf woody plants. Typical animals include snowy owls, musk ox, reindeer, polar bears, and migrant birds.
B. BOREAL FOREST (TAIGA): dense evergreen needle-leafed forest Typical plants include white spruce, black spruce, and jack pine. Typical animals include moose, black bears, wolves, and migrant birds. Cold winters with deep snow, but longer growing season than tundra. Warm-month average temperature greater than 10 o C. Periodic fires common.
C. TEMPERATE FOREST: dense forest with thin, broad, deciduous leaves; or rainforests typically dominated by conifers. Tall trees with single boles creating deep shade. Understories often sparse. Typical plants include maples, oaks, elms (deciduous) spruce or auraucaria (rainforest). Typical animals include deer and squirrels.
D. GRASSLANDS (STEPPE): treeless vegetation less than 1 m high. Typical plants include grasses and members of the sunflower family. Woody plants predominate in steppes. Typical animals include large grazing ungulates such as horses, buffalo, and rhinoceros. Cold or warm winters with growing seasons moisture too dry for trees; fires every 1-5 years.
E. WOODLAND (CHAPARRAL): sparse to dense woody vegetation of low trees and shrubs, typically with very thick, tough evergreen leaves. Summers with little rain, fires every 5 - 20 years. Typical plants include oaks, manzanita, chamise, low pines, and junipers. Typical animals include birds and reptiles.

A biome is a geographically extensive type of ecosystem. A particular biome occurs wherever environmental conditions are suitable for its development, anywhere in the world. Biomes are characterized by the life forms of their dominant organisms, but not necessarily by their particular species. On land, biomes are generally identified by their mature or older-growth vegetation. In contrast, aquatic biomes are usually distinguished by their dominant animals. Biomes are classified using a system that is used at an international level—that is, by ecologists working in many countries.

Seashores are an interface of terrestrial and oceanic biomes and they support a complex of coastal ecosystems. The seashore biome is locally influenced by physical environmental factors, especially bottom type, the intensity of wave action, and the frequency of major disturbances such as storms.
In other words, the different species are comparable in their form and function, because the regimes of natural selection occurring in similar environments result in parallel (or convergent) evolutionary responses. Therefore, biomes are defined primarily by the structure and function of their ecosystem, but not necessarily their species composition.
The same biome may occur in far-flung places, even on different continents, and in such cases it will be similar in structure and function but will usually be dominated by different species. Temperature and moisture availability are the most critical environmental factors affecting the distribution of terrestrial biomes. Marine biomes are most influenced by depth, nutrient availability, and temperature.
Tropical rainforest represents the peak of development of terrestrial ecosystems because the biome supports huge biomass, high productivity, and rich biodiversity under relatively benign climatic conditions. Image 8.6.
Learning about biomes is important because it provides insight into the character and environmental influences on major kinds of ecosystems.
