Forest is one of the constituent parts of the world, a system of animate and inanimate nature (air, water, earth).It is a place covered with plantations of trees, shrubs, fungi and other plants.Almost a third of the planet's land filled with forests.

What are they?

There are different classifications of forests.Consider some of their species:

  • Distinguish boled and nizkostvolnye forest.Boled - a tree grown from seed, and nizkostvolnye - from germs.
  • forests are divided into aggregate plantings of the same breed and mixed when it encounters two types (or more) of trees.
  • by age - young, medium and old.

Another classification

Separately allocate European classification of forests:

  • those located in the northern and temperate zone.Here you can see the evergreen coniferous forests, separately grown man parks, groves, which are mainly dominated by broad-leaved trees, dense forests, and forest, which presents different species of wood.
  • forests are in the tropics and subtropics.Here is dominated by mountains, thorny impenetrable forest, woods, grown in the marshes or exotic plants.

accepted that the earth's surface covers a multitude of illegally grown trees, shrubs and other organisms that feed on air and inorganic substances from the soil, depending on the climatic zone of their location.So, in the northern zone of frequent dense forest, deciduous-fir, kustarnopodobnye Proleski.Due to the fact that the northern part of the Earth's least populated areas, and infrastructure is poorly developed, the air in these parts is particularly clean.Often there are edge - a band, where the forest smoothly into the adjacent vegetation.Special attention should be dense forest - is the thick, overgrown, impassable or even impassable.It is usually inhabited by wild animals.

In the tropics, there are wet rainy forests, basically, they are growing in the marshes, forming thickets.The area of ​​the forest is not clearly delineated, smooth transitions from one ecosystem to another hardwood.Presented set of lianas, woody plants that cling to the other bioorganisms.It's not often you can find a dense forest overgrown, people bypass these impenetrable thickets party to be in them is very dangerous.

who lives in the woods?

Fauna - an integral part of the forest nature.The inhabitants of diverse species and their dispersal depends on specific ecosystems.Animals such as bear, fox, deer, beaver, partridge, mobilized on the cool areas.Tigers, monkeys, mongooses live in warm countries.Dense forest, which is found everywhere, populated mainly wild animals: elk, wild boars, hyenas.More often than in other forests, there are snakes.

green plantation forests play an important role in the life of man and nature as a whole, as has been actively involved in the circular circulation of oxygen, water, and have a huge impact on the gas flow in the ecosystem.In addition, the forest has beneficial effects on the human psyche is a powerful antidepressant.

people by their actions, however, are often detrimental to the forest system.Since the trees are a source of energy and raw materials, constantly extends their cutting to restore new territories must be at least ten years.Because of improper behavior in nature often have fires.Biggest threat in this case carries a dense forest, which is very cumbersome to extinguish the flames, which in this case is distributed immediately.

Conclusion

teach people why it is necessary to protect nature from an early age.From its safety depends on the livelihoods of all humankind.
