Forest structure

Emergent layer

which grow above the general canopy, reaching heights of 45–55 m, although on occasion a few species will grow to 70–80 m tall

The emergent layer contains a small number of very large trees, called emergents

Canopy layer

It contains the majority of the largest trees, typically 30–45 m in height. Tall, broad-leaved evergreen trees are the dominant plants.

The canopy is the primary layer of the forest forming a roof over the two remaining layers.

Understory layer

Only about 5% of sunlight breaches the canopy to arrive at the understory

he understory is home to a number of birds, small mammals, insects, reptiles, and predators

The understory layer lies between the canopy and the forest floor.

Forest floor

only plants adapted to low light can grow in this region

the bottom-most layer, receives only 2% of the sunligh

Climate Characteristics

This high level of precipitation often results in poor soils due to leaching of soluble nutrients.

can exceed 1,000 cm (390 in) although it typically lies between 175 cm (69 in) and 200 cm

Average annual rainfall is no less than 168 cm

Mean monthly temperatures exceed 18 °C (64 °F) during all months of the year

Where Can we find it?
