What is a Rainforest?

Introduction Rainforests nearest to the equator, where the climate is very hot and wet all through the year, are evergreen because the trees can grow all of the time and so are always in leaf. Read More: Why are Rainforests Important?

Emergents are the tallest trees and are usually over 50 metres tall. The Kapok tree is an example of an emergent. The sea of leaves blocking out the sun from the lower layers is called the canopy. This includes birds, snakes and monkeys.

    Lianas vines climb to the canopy to reach this sun light. The under canopy mainly contains bare tree trunks and lianas. The shrub layer has the densest plant growth. It contains shrubs and ferns and other plants needing less light. Saplings of emergents and canopy trees can also be found here. The forest floor is usually dark and damp. It contains a layer of rotting leaves and dead animals called litter. This decomposes rapidly within 6 weeks to form a thin humus, rich in nutrients.

    Th e high rainfall and year-round high temperatures are ideal conditions for vegetation growth. The wide range of plants encourage a huge variety of insects, birds and animals. How has vegetation adapted to the climate? In the tropical rainforest most trees in the rainforest have wide buttress roots. This is to support them as they grow incredibly tall over ft in some cases as there is great competition for sunlight. Lianas vines grow around trees as they bid to reach sunlight. The leaves of many trees are waxy and have drip tips to allow water to run off them so that water does not gather on leaves and cause them to rot, it also allows water to reach the roots on the forest floor.

    Why Are Rainforests Important?

    Leaf stems are also flexible to allow leaves to move with the sun to maximise photosynthesis. Deforestation cutting down trees is a major problem caused by humans in the tropical rainforest.

Slash and burn Most clearances are still by the local people and tribes needing land on which to grow crops. Vegetation is cut down and then burned. The ash acts like a fertiliser adder nutrients to the soil. When the soil begins to turn infertile usually after years the people move on.

    This is called shifting cultivation.
