Transcript of Virtual Field Trip: Taiga Cordillera

Taiga Cordillera Virtual Field Trip Where is the
Taiga Cordillera? Human Activities/Settlements How were these landforms created? Landforms/Geology Wildlife •Needle Bearing Trees
•Leaf Bearing Trees
•Major Vegetation Vegetation •Sparsely populated
•Home of the Vuntut Gwich’in people
•Total population of 300 people
•Much of the area is untouched wilderness Kayli Chen Ms. Tang •Takes up Most of northern Yukon
•Takes up portions of the border between the Yukon and the Northwest Territories
•Surrounded by the Boreal Cordillera and the Taiga Plains Location •Made up of a steep, mountainous terrain with a series of sharply etched ridges and narrow valleys •Also consists of rolling foothills, upland plateaus, and low-lying basins. Well... •Half a billion years ago, the area was a shallow marine platform
•Sand, mud, and gravel were deposited by Rivers flowing off the protocontinent
•The sand, mud, and gravel created sandstones, mudstones, and shales that make up a lot of the sedimentary rocks that we see today
•The skeletal debris of marine organisms also created limestone and dolomite •About 200 million years ago, folding and uplifting started to effect the original sedimentary rocks
•As the platform on which the sedimentary rocks laid on slowly drifted west, it collided with other crustal plates in its path
•The results of the collisions were new chains of mountains
•Because of the local stresses beneath the Earth's crust, red-hot molten rock was forced toward the surface, producing the igneous rocks that we see today Soils •The soil is similar to that of the tundra's
•Because of the cycle of freezing and thawing, there are some permafrost-rich soils
•Since the water from precipitation and melting snow cannot seep through the permafrost, the ground remains soft and damp in some parts
•The soil is very infertile and very few plants can grow
•The soil has a high acid content •Mammals
•Birds
•Water Fowl Species •American Pika
•Hoary Marmot
•Grizzly Bear
•Dall's Sheep Common in Alpine Terrain Tundra-Adapted Birds •White-tailed Ptarmigan
•Horned Lark
•Water Pipit. Common in Lower Forested Habitats •Woodland Caribou
•Lynx
•Marten
•Black Bear Common is Lower Forested Habitats •White-winged Crossbill
•Varied Thrush
•Gray Jay •Canvasback
•Common Golden-eye
•Mallard
•Trumpeter Swan (rare) Found in River and Wetland Habitats Climate •Low rate of evaporation
•Mountains block much of the precipitation
•Averages 250 to 300mm of precipitation per year •Averages a temperature of -22ºC during winters •Averages a temperature of 8ºC during summers
•Mean annual temperatures range from –10°C in the north to –4.5°C in the south
•Has cold winters with very short days
•Has short, cool summers
•Snow lasts on the ground for six to eight months of the year. •Lichens
•Sedges
•Mosses •Alpine Fir Tree
•Black Spruce Tree
•White Spruce Tree
•Lodgepole Pine Tree •Willow Tree
•Shrub Birch Tree
•Trembling Aspen Tree
•Paper Birch Tree Found in the Subalpine Transition Zone and the Montane Zone Found in the Subalpine Transition Zone and the Montane Zone Found in the Lowland Zone •Balsam Poplar Tree
•Willow Tree
•Alder Tree Influences of Vegetation •Position on mountain slopes
•Amount of available soil, moisture, and sunlight
•Clouds deposit most of their moisture on western slopes before continuing east
•Western slopes have more luxuriant plant cover Cause of Array of Species •Diversity of habitats
•Dense spruce forests to arctic tundra
•Alpine mountain peaks to marshy flats
•Both arctic and temperate climates Local economy •Tourism (some)
•Hunting
•Trapping
•Fishing
•No industries
•No urban centers Old Crow:
•Major City
•Home of One of Yukon's Major Airports
•Biggest City in the Taiga Cordillera Interactions Landforms & Vegetation Soils & Vegetation Climate & Human Settlements •South-facing slopes are warmer and drier (conditions that favour soil nutrient release and plant growth)
•North-facing slopes grow plants that adapted to cold climates •Since a lot of the soil is permafront, very few plants can grow
•Very Infertile •Since the climate is extremely cold and humid, with long, dark winters and short, cool summers, not many people want to live there Thanks for listening! Bibliography www.allaboutbirds.org/guide/Varied_Thrush/id
