The forest floor, the bottom-most layer, receives only 2% of the sunlight. Only plants adapted to low light can grow in this region. Away from riverbanks , swamps and clearings, where dense undergrowth is found, the forest floor is relatively clear of vegetation because of the low sunlight penetration.
[14] [45] The rainforest's high humidity supports epiphytic plant species at greater height and diversity than elsewhere in the eastern United States. [15] A wide range of mosses, ferns, and liverworts have been identified as high as 140 feet (43 m) above the forest floor. [15]
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 ...
A portion of the temperate rain forest region of North America, the largest area of temperate zone rainforests on the planet, is the Pacific temperate rain forests ecoregion, which occur on west-facing coastal mountains along the Pacific coast of North America, from Kodiak Island in Alaska to northern California, and are part of the Nearctic realm.
Spiny forest at Ifaty, Madagascar, featuring various Adansonia (baobab) species, Alluaudia procera (Madagascar ocotillo) and other vegetation. The main layers of all forest types are the forest floor, the understory, and the canopy. The emergent layer, above the canopy, exists in tropical rainforests.
Hoh Rainforest is the wettest forest in the Contiguous United States, receiving 129 inches (3,300 mm) of rain per year. It is an Oceanic climate ( Köppen climate classification : Cfb), with a much higher rainfall during the winter.
The rooms' designs are even influenced by the layers of the surrounding rainforest, from the forest floor to the canopy, to encourage guests to celebrate nature's rich biodiversity. Courtesy of ...
In northern Idaho rainforest patches along the Clearwater River, a mean annual temperature of 5.4°C has been measured. [8] In British Columbian Inland rainforest areas, the mean annual temperature ranges from 2.7 to 4.5°C. In the coldest months, the mean temperature of these region lies between -8 and -9.5°C. [9]
