Layers of the Rainforests In tropical rainforests, the vegetation grows in four main layers, much like a sandwich has layers.

Layers of the RainforestsEmergentsThe tallest trees in therainforest are emergents,towering as high as 40-60metres above the forestfloorThey are called emergentsbecause they ‘emerge’from the general canopy oftrees.Sunlight is plentiful
Layers of the RainforestsCanopyRainforest trees form a covering or ‘canopy’ thatrestricts the amount of light that makes its way to theforest floor.The canopy extends 25-45 metres above the forestfloor.It is very important to the rainforest ecosystembecause it maintains a moist and cool microclimateThere are many flowers and fruits in the canopy
Layers of the RainforestsUnderstoreyThis layer only gets about 2-5% of the sunlightavailable to the canopy.It is made up of layers of trees whose growth islimited by the taller trees of the canopy.Plants in the understorey include the brushbloodwood, sandpaper fig, prickly tree fern and dwarfpalm.They rarely grow more than 3.5 metres.

Layers of the RainforestsForest FloorThe forest floor is thick with leaf litter, seeds, fruit andbranches, which decay to form humus which is therich top layer of soil.The humus provides rich nutrients for further plantgrowth.There is a lot of competition for these nutrients andthat is why many trees are shallow-rooted.
