Biomes are classified according to their dominant vegetation. The temperate rainforest biome receives ample rainfall between 20-60 inches per year and has rich, moist soil that supports tall trees and few understory plants due to lack of sunlight. However, 87% of North American temperate rainforests have been destroyed by human activities like deforestation, pollution, and development. Conservation efforts aim to replant forests but often cannot restore the original diversity.

2. 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

3. Locations
Eastern Asia
Central and Western Europe
Eastern United States

4. Locations

6. Major Geographical Features
Water
Lakes
Rivers
Streams
etc.

7. Major Geographical Features
Mountains
Rocky Mountains
Appalachian Mountains
ChangBai Mountains
etc.
Humid temperate rain forest in Gilan
Province, northern Iran

8. Climate
Highs of 86 degrees Fahrenheit
Lows of -22 degrees Fahrenheit
Temperatures vary by over 100 degrees in a year

9. Climate
Receive ample amounts of rain
Between 20-60 inches per year
In the form of rain or snow

10. 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.

11. 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

12. Fauna
Squirrels Timber Wolves
Rabbits Foxes
Skunks Black Bears
Birds Mountain Lions
Deer Bobcats

13. Deforestation

14. 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

15. Deforestation
Conservation Efforts
Replanting
Replanting usually does not provide the same diversity
originally found in the forest

16. 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
