World Distribution of Forests
Northern Coniferous Belt
Climate conditions are very cold and harsh Only coniferous trees are suited to these
conditions as deciduous trees are unable to survive in these conditions
Examples: larchbirchdouglas fir
sitka spruce
Northern Template Belt
Climate is mild and the soil conditions are good
Consists of both coniferous and deciduous trees
As this region is densely populated it does not contain large forest areas
Examples: OakAshMaple Sitka spruce
Tropical Rainforests
Climate has high rainfall and high temperature
This area runs around the equator As there are no seasons, growth occurs all
year round Examples: Mahogany
BalsaEbonyTeak
Southern Temperate Belt
Climate is mild and seasonal Consists of both coniferous and deciduous
trees Less land in this region compared to
others Examples: Oak
BeechParana PineEucalyptus
Deforestation
Deforestation is the destruction of large forests areas without replanting trees cut down
Timber is a renewable resource only when it is managed properly and trees replanted when cut down
In tropical regions forests are been cut down and not replanted
It is estimated areas the size of Ireland are been lost each year
Reasons for Deforestation
Large areas cleared for farming and ranching (slash and burn technique)
High demand for tropical hardwood Natives of some regions use timber as an
economical source of fuel for heating and cooking
Commercial interests of large multi-national and local logging companies
Effects of Deforestation
Slash and burning methods kill all animals, birds and insects causing many to become extinct
Burning of trees contributes to air pollution Number of trees available to consume CO2 and
produce O2 is reduced, causing the greenhouse effect
Effects the weather and global climate Increases soil erosion in deforested areas Native tribes are removed from their homes Flooding – as trees consume large amounts of
water their removal can cause the water table to rise
How to Prevent Deforestation
Only use tropical woods that are grown in managed forests (for each tree cut down one is replanted)
Where possible use manufactured boards rather than solid tropical hardwoods
Try to recycle wood and wood products - paper
