Because of the lack of seasonal differences, due to the geographical location of the forests, and the high humidity level the vegetation is luxuriant here. The recurring features of rainforests are basically the following:
high animal and vegetal biodiversity
evergreen trees
dark and sparse undergrowth interspersed with clearings
scanty litter (organic matter settling on the ground)
presence of “strangler” creepers
presence of “buttresses” (i.e. large winged ribs at the base of trunks) and spindly roots in trees living in often-flooded areas.
