The emergent layer contains a small number of very large trees called emergents, 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. [21] [22] They need to be able to withstand the hot temperatures and strong winds that occur above the canopy in some areas.
The structure of a tropical rainforest is stratified into layers, each hosting unique ecosystems. These include the emergent layer with towering trees, the densely populated canopy layer, the understory layer rich in wildlife, and the forest floor, which is sparse due to low light penetration. The soil is characteristically nutrient-poor and ...
Many rainforest animals have evolved to live solely in the canopy and never touch the ground. The canopy of a rainforest is typically about 10 m thick, and intercepts around 95% of sunlight. [9] The canopy is below the emergent layer, a sparse layer of very tall trees, typically one or two per hectare. With an abundance of water and a near ...
The canopy can be divided into five layers: overstory canopy with emergent crowns, a medium layer of canopy, lower canopy, shrub level, and finally understory. [1] [3] [4] The canopy is home to many of the forest's animals, including apes and monkeys. Below the canopy, a lower understory hosts snakes and big cats.
Emergent layer exists in a tropical rain forest and is composed of a few scattered trees that tower over the canopy. [ 39 ] In botany and countries like Germany and Poland, a different classification of forest vegetation is often used: tree, shrub, herb, and moss layers (see stratification (vegetation) ).
Rainforest vegetation is categorized by five layers. The top layer being the emergents, or the upper tree layer. Here you will find the largest and widest trees in all the forest, commonly 165 feet (fifty meters) and higher. These trees tend to have very large canopies so they can be fully exposed to sunlight.
Some of the important tree species found in this forest area are – Hollong, Mekai, Dhuna, Uriyam, Nahar, Chamkothal, Bher, Hollock, Nahor, Ou–tenga (elephant apple), different species of Ficus spp. etc. The towering Hollong tree which is also the State Tree of Assam dominates the emergent layer of this rainforest.
The top layer is the emergent (or dominants) where the tallest trees are found (up to 200 feet tall). Many birds, such as eagles and parrots, also reside in the emergent. The primary layer is the canopy where about 70 to 90 percent of all rainforest life resides. Plants in this layer have a large amount of fruit, seeds and flowers.
