(5 types)
1. Coniferous forests
2. Temperate deciduous forests
3. Tropical rain forests
4. Temperate evergreen forests
5. Temperate rain forests

13. 1.Coniferious
forest
• Cold windy region near poles
• Conifers are adapted to withstand long
drought like conditions of the long
winters

14. 2.Temperate
deciduous
forest
• Occur in areas of moderate temperature
and rainfall with cold winters.
• Species belonging to these forests shed
their leaves in autumn
• Tropical deciduous forest shed their
leaves at December.

• Experience an average temperature of
26 degree Celsius
• Contain large amount of natural
medicines
• Coffee, chocolate, banana, mango,

17. Temperate
evergreen
forests
• It encompass the wet temperate and
subtropical conifer forests of North
America, as well as subtropical
evergreen broadleaf forests and
eucalyptus forests of southern
hemisphere
• Hardy leaves
• Dominated by pines
• Also has fir, hemlock, oak, giant sequoia

18. Temperate
rain forest
• Rainfall minimum of 200 cm and upto
350 cms in warmer areas
• Precipitation may be snow or rainfall in
higher elevations
• Annual average temperature is 0ºC
• Warmest of temperature is 20ºC
