Tundra is the coldest of all the biomes
It comes from the word tunturia, a Finninsh word which means treeless plain
Noted for frost-molded landscapes
CHARACTERISTICS
CHARACTERISTICS OF TUNDRAExtremely cold climate
Low biotic diversity
Simple vegetation structure
Limitation of drainage
Short season of growth and reproduction
Energy and nutrients in the form of dead organic material
Large population oscillations
ALPINE TUNDRA
Alpine Tundra
Found on tops of tall, cold mountains
No trees grow on this biome
Soil is well drained
Nighttime temperature is below freezing point
PLANTS IN ALPINE TUNDRATussock grasses
Dwarf Trees
Small-leafed shrubs
Heaths
ANIMALS IN ALPINE TUNDRAMammals
– pikes, marmots, mountain goats, sheep elk
Grouselike birds
Insects – Springtails, beetles, grasshoppers, butterflies
ARCTIC TUNDRA
Arctic Tundra
Found in the Northern Hemisphere encircling the north pole
Soil is frozen. Permafrost or permanent ice.
Water is unavailable most of the year.
Annual precipitation is very low, less than 10 inches or 25 centimeters
PLANTS in ARCTIC and SUB-ARCTIC Low shrubs, ridges, reindeer mosses, liverworts, and grass
400 varieties of flower
Crustose and folioce lichen
ANIMALS IN ARCTIC Musk Ox, Arctic Wolf, Brown Bear
Factors that Destroy the Tundra
Carbon dioxides in the atmosphere are poison.
Carbon dioxide is given off by plants that die and decompose.
The tundra is a carbon dioxide sink.
The tundra traps carbon dioxide because the frost prevents plants from dying.
Global warming melts the tundra, which melts the layers of frost, and returns huge amounts of carbon dioxide to the atmosphere.
Preventing Destruction of the Tundra
Leave the tundra undisturbed. Miners and oil drillers who move into the tundra kill the animals and disrupt the ecosystem. They use pesticides to kill the hordes of insects. Migrating birds feed on these insects and die because of the pesticide inside the insects.
The miners and drillers have polluted the tundra lakes and rivers, which caused the death of plants in the surrounding area.
From the Philippines, we can help save the tundra by not contributing to global warming. Global warming heats up the atmosphere, which reaches the tundra and melts it.
