The Tundra By: Jake and Ashley
What is the Tundra? The tundra is a vast, flat, treeless Arctic region of Europe, Asia, and North America in which the subsoil is permanently frozen.

Extremely cold climate Low biotic diversity Limitation of drainage Short season of growth and reproduction Energy and nutrients come in the form of dead organic material Simple vegetation structure
Climate The average temperature is:
• Winter -34C (-30F) • Summer 3-12C (37-57F)
The average precipitation including snow is:
• 15 to 25 cm (6 to 10 inches)
The tundra has two seasons:
• Summer lasting 6-10 weeks • Winter lasting 6-10 months Climate is the prevailing attitudes, standards, or environmental conditions of a group, period, or place.
About the Tundra Wind speeds can range from 30 to 60mph
The growing season last for only 50 to 60 days.
The mineral deposit is oil
A growing season is the period of each year when native plants and ornamental plants grow; and when crops can be grown.
Location
The Arctic tundra is located n the northern hemisphere, ncircling the north pole and xtending south to the oniferous forests of the taiga. A coniferous forest is a type of orest characterized by conebearing, needle-leaved trees.
The Alpine tundra is located on mountains throughout the world at high altitude where trees cannot grow.
The Tundra is located 66 degrees north of the equator.
Countries The arctic tundra is located in the following countries:
Antarctica
North pole
Northern Canada
Alaska
Greenland
Dangers for the Tundra
The biggest natural disaster that could harm the arctic tundra is global warming. With global warming, temperatures will increase causing the permafrost layer of soil to melt.
Human activities like air pollution cause smog that comes from any industrial factories. Smog is a type of air pollution. Offshore and onshore oilrigs cause a threat to ruin the natural habitat to many species including the polar bear.
What lives here? In the summer season’s caribou tend to travel to arctic regions. The arctic tundra is only bearable in the summer season. The winter months certain kinds of birds and animals travel to the tundra to nest and feed.
Plants such as grasses, shrubs, liverworts and mosses have to adjust to permafrost. It is a layer of permanently frozen subsoil. There are over 1700 kinds of plants in the arctic and sub arctic tundra.
Some abiotic factors in Arctic tundra are winds, low precipitation, and poor soil. Biotic factors like snowy fox, and different kind of mosses live in the area.
Pl ant s Bearberry is a low growing plant. All parts of the plant can be used in some way. The fruit off of the plant can be used with different foods. The roots can be used to make tea that helps constant coughing. The tea also helps kidney and bladder problems. Another plant called a pasque flower grows low like all plants in the tundra plants grow low due to permafrost.
