What is the tropical evergreen forest?

Evergreen trees do not drop their leaves (needles) when the season changes therefore, they are forever (or ‘ever ‘) green. The tropical evergreen forests usually occur in areas receiving more than 200 cm of rainfall and having a temperature of 15 to 30 degrees Celsius. They occupy about seven per cent of the earth's land surface and habours more than half of the world’s plants and animals. They are found

mostly near the equator.

These forests are dense and multi-layered. They harbour  many types of plants and animals. The trees are evergreen as there is no period of drought. They are mostly tall and hardwood type. Leaves are broad and give out excess water through evapo-transpiration.

The characteristic features of Tropical evergreen forests are the following:

  • high animal and vegetal biodiversity .The tropical rainforest are very Biodiverse , they have some great diversity of Orchids, Birds, mammals and plants. They have high Species richness.
  • Obviously evergreen trees
  • Sparse undergrowth interspersed with clearings. The rainforest nutrient cycling is rapid. The hot, damp conditions on the forest floor allow for the rapid decomposition of dead plant material. This provides plentiful nutrients that are easily absorbed by plant roots. However, as these nutrients are in high demand from the rainforest's many fast-growing plants, they do not remain in the soil for long and stay close to the surface of the soil. If vegetation is removed, the soils quickly become infertile and vulnerable to erosion.
  • Rainfall is high and so is the temperature.Take a look at this graph. It is due to the geographical location. It receives max Insolation that results into high rate of evapotranspiration resulting into condensation and eventually precipitation
