The shrub layer is the stratum of vegetation within a habitat with heights of about 1.5 to 5 metres. This layer consists mostly of young trees and bushes, and it may be divided into the first and second shrub layers (low and high bushes). The shrub layer needs sun and little moisture, unlike the moss layer which requires a lot of water.
The trees found in the third layer include young trees trying to grow into the larger canopy trees, and "palmoids" or "Corner Model Trees". The fourth layer is the shrub layer beneath the tree canopy. This layer is mainly populated by sapling trees, shrubs, and seedlings. The fifth and final layer is the herb layer which is the forest floor.
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 ...
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.
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 ...
Borneo rainforest. Some tropical forest types are difficult to categorize. While forests in temperate areas are readily categorized on the basis of tree canopy density, such schemes do not work well in tropical forests. [1] There is no single scheme that defines what a forest is, in tropical regions or elsewhere.
The geology of these forests is primarily composed of folded and metamorphic hills, which are covered by a thin layer of alluvium (loose sediments and soil). [8] The bedrock is sedimentary and rich in silica and dates back to the Precenozoic periods when much of the region was underwater.
