Biomes

Biomes are the world’s major communities

Classified according to the predominant

vegetation

Human activity can alter biomes

87% of the North American Temperate Rain Forest

have been destroyed by human activities

Locations

Eastern Asia

Central and Western Europe

Eastern United States

Major Geographical Features

Humid temperate rain forest in Gilan

Province, northern Iran

Climate

Highs of 86 degrees Fahrenheit

Lows of -22 degrees Fahrenheit

Temperatures vary by over 100 degrees in a year

Climate

Receive ample amounts of rain

Between 20-60 inches per year

In the form of rain or snow

Soil

Often have soil that is very rich in nutrients because organisms die and decompose

Dark and moist

Nurse logs act as soil for many new plants on the forest floor

Soil can erode because timber operations and slash-and-burn farmers destroy plants that hold the soil in place.

Flora

Trees dominate

Oakes –over 600 different species

Maples – green, yellow, or red leaves

Hickory – baseball bats

Few plants grow on forest floor because almost no sunlight reaches them

Plants grow as tall as possible to receive the most sunlight for photosynthesis

Fauna

Squirrels

Rabbits

Skunks

Birds

Deer

Timber Wolves

Foxes

Black Bears

Mountain Lions

Bobcats

Deforestation

Deforestation

In the last 5,000 years, humans have reduced

forests from roughly 50% of the earth’s land

surface to less than 20%

Thailand will have no forest left in 25 years

Philippines will have no forest left in less than 20

years

Nepal will have no forest left in 15 years

Deforestation

Conservation Efforts

Replanting

Replanting usually does not provide the same diversity

originally found in the forest

Pollution

Especially effects forests at high altitudes

Pollutants:

Acid deposition (acid rain)

Damages tree leaves

Exposes to toxic chemicals

Restrictions are being placed on transportation and manufacturing to limit pollution
