The definition of a forest varies around the world, but the main characteristics are the same - it is an region that is densely planted with tall trees, and covers a large area. More than 50 per cent of Earth's animal and plant species can be found here.

Types  of   forest

  • Rainforest

Lush tropical forests are found in hot regions with high rainfall, usually around the tropics of Cancer and Capricorn.

  • Tropical dry forest

Vegetation that can survive the long, parched months of a dry season grow in theses forests.

  • Coniferous  forest

Vast areas of coniferous forest stretch across the cold regions of  North America, northern Europe, and Asia.

Temperate forest

In areas with distinct  cool and warm seasons grow broad leaved trees that lose their leaves in the winter months.

About 300 million peoples are born, live, and die in the world's forests, and 60 million of them are almost totally dependent on the forests to maintain their lifestyle.

Forested regions 


USA - Many of the USA's forested areas are protected as national parks

Canada - Almost one million Canadians are involved in the country's forest industry

Russia - About 20 per cent of the world's  forest can be found in the largest country on Earth

Brazil - The Amazon rainforest covers more than half of Brazil and is the largest remaining tropical rainforest on Earth

Central Africa - This tropical rainforest is home to 11,000 plant species and more than 400 species of mammal

China - Forests in China grew by 1.2 per cent every year between 1990 and 2000, the highest growth rate in the world

The trees of  Amazon rainforest have their roots in nine different countries

Brazil

Peru

Colombia

Venezuela

Ecuador

Bolivia

Guyana

Suriname

French Guiana


What is deforestation ?  

The clearing away of  trees, know as deforestation, affects our planet in a variety of  ways.


It destroys forest habitats and kills the animals living there.
Two - thirds of  all species on Earth need  forests for shelter or food.

The lower number of  trees to convert carbon dioxide into oxygen contributes to global warming.

Trees give off water vapour, so the fewer trees there are, the less water there is in the atmosphere.

Without trees roots to hold the soil together, there is an increased chance of  soil erosion, flooding, and landslides.

How to : reach the top of  a rainforest

1. Start in the damp, shady forest floor. In some forests, only two per cent of  light reaches this area, which is covered in leaves and roots.

2. Climb up to about 15 m (50 ft) from the floor. You're now in the understory where small trees can branch out.

3. Stop off at the canopy, where the tops of taller trees spread out to form a dense canopy that traps sunlight.

4. Arrive at the top, known as the emergent layer. Here the very tallest trees reach the sky, sometimes at a height of  70 - 80 cm ( 230 - 262 ft) above ground.


About 30 per cent of Earth's total land area is forested.

The Amazon rainforest contains an amazing variety of flora and fauna. ( In numbers)

1 millon - insect species

40,000 - Plant species

3,000 - fish species

428 - amphibian species

427 - mammal species

378 - reptile species

1,294 - bird species


More than five million native Indians once lived in the Amazon rainforest, but now only about 200,000 remain.
Forest fires 

Fires can sweep through forests causing huge devastation to trees, plant and animals life. 

   However they can also help regenerate a habitat by clearing  the area for new growth and leaving a layer of rich ash where new seeds will flourish. 

The main causes of  forest fires are these:


  • human activity or deliberate fire - starting ( arson)
  • lightning
  • excessively hot and dry conditions help the fire spread
