Tropical rainforest. View of a tropical rainforest. Tropical rainforests are hot,humid forests in tropical areas where there is little seasonal variation in temperature (21-32 degrees C) and heavy rain all year (at least 2500mm). They are characterised by a great diversity of plant and animal species,a closed canopy layer which allows little light to reach the forest floor,and rapid nutrient cycling within the forest. Rainforests cover only 7% of the Earth's land surface but contain over half the planet's species. Photographed in the Corcovado National Park,Costa Rica | |
