Climate

• In the middle latitudes, the prevailing winds
  carry moisture-laden air masses over the west
  coasts of the continents, which receive
  substantial rainfall in consequence.
• The region covered by temperate rain forest
  experiences mild, wet winters and cool, foggy or
  cloud-covered summers. The mild winters permit
  year-round growth of the conifers, while the mild
  summers reduce the possibility of drought.
• Rainfall 1500 3500 mm per year
• Temperature 0 25

Distribution

• These forests line the coast of North America
  from central California north to south-eastern
  Alaska.
• Despite its similar climate, the much-interrupted
  coast of north-western Europe lacks this type of
  evergreen forest, which was eliminated during the
  last period of glaciation.
• Small areas of temperate rainforest are found in
  North-eastern Asia.
• In the southern hemisphere, temperate rainforests
  of southern beeches, podocarps, and other species
  are well developed in central Chile and on
  Tasmania and the South Island of New Zealand.

Soil

• This forest has nutrient-rich soil because there
  is a lot of dead organic matter on the ground.
  This dead material is being slowly digested by
  the fungi, insects, and bacteria that live here.

Plants I

• Although temperate rain forest has layers of
  tall, medium, and low growing vegetation, the
  cool winters limit the numbers and kinds of life
  forms that live here. Compared to the tropical
  rain forest, the temperate rain forest has a less
  complex ecology. For example, the topmost layer
  of the temperate rain forest on the western edge
  of North America is dominated by four kinds of
  tall coniferous trees.
• The forest floor is covered by ferns, mosses, and
  small plants. Mosses and lichens grow on the tree
  trunks and rocks.

Plants II

• In the tropical forests the trees have to spend
  some of their energy drawing up water and getting
  rid of heat in this milder climate the trees can
  grow and grow.
• Scientists say that there is more biomass in this
  biome than in any other biome on earth. There may
  be 500 tons of living things per acre here.

Animals

• Most of the animals in this forest live on or
  near the ground, where there is lots of food, and
  the trees provide shelter from sun, wind, and
  rain. Beetles burrow in the moss and hide in the
  bark of trees. Wood peckers and birds eat the
  insects. Grass is eaten by the voles (cute little
  mouse-like animals) and deer.

People

• The primary causes of forest loss and degradation
  vary from region to region. They include
  agricultural expansion, mining , settlement,
  shifting agriculture, plantation establishment
  and infrastructural development.
• While logging is one of the most important causes
  of forest loss and degradation, the way the
  logging industry operates also exaggerates the
  problem.
