T ropical and temperate rainforests share certain characteristics. For example, most trees flare at the base.
Vegetation is dense, tall and very green .
Many species exist in both rainforests, although the diversity is greater in the tropical rainforest. B oth tropical and temperate rainforests are very lush and wet. The tropical rainforest has downpours at the rate of two inches an hour adding up to some 400 inches of rain per year. And even more moisture comes from the coastal fog that hovers among the trees. Only a small percentage of the tropical forests are rainforests.
