The third layer is the lower tree area. These trees tend to be around five to ten meters (16 to 33 feet) high and tightly compacted. 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.
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.
A tropical rainforest typically has a number of layers, each with different plants and animals adapted for life in that particular area. Examples include the emergent, canopy , understory and forest floor layers.
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.
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 ...
are characterised by trees with dense, horizontally or obliquely-held foliage in the upper layers. are described in terms of leaf size: mesophyll – more than 12.5 cm long (45 – 100 cm 2), e.g. tropical rainforest; notophyll – 7.5 - 12.5 cm long (2 – 45 cm 2), e.g. warm temperate rainforest

With annual forest loss of 0.3% during the 2000s, [5] the region had the lowest deforestation rate of any major tropical forest zone. [6] From 2015 to 2019, the rate of deforestation in the Democratic Republic of the Congo doubled. [7] In 2021, deforestation of the Congolese rainforest increased by 5%. [8]
