Fungi are also very common in rainforest areas as they can feed on the decomposing remains of plants and animals. The great diversity in rainforest species is in large part the result of diverse and numerous physical refuges , [ 25 ] i.e. places in which plants are inaccessible to many herbivores, or in which animals can hide from predators.
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 ...
Thousands of trees have been planted by volunteers as part of a new temperate rainforest in south Devon. More than 2,500 native trees have been planted so far this winter at Devon Wildlife Trust's ...
The canopy level is the third level of the temperate rainforest. The trees forming the canopy, conifers, can stand as tall as 100 metres or more. A variety of species survive in the canopy. The tops of these trees collect most of the rain, moisture, and photosynthesis that the rainforest takes in. They form a canopy over the forest, covering ...
A Sapele tree in the Republic of the Congo. The Congolian rainforest is the world's second-largest tropical forest, after the Amazon rainforest.It covers over 500,000,000 acres (2,000,000 km 2) across six countries and contains a quarter of the world's remaining tropical forest.
An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus, live oak, acacias, magnolia, and banksia in more temperate zones, and rainforest trees in tropical zones.
Young western hemlock growing as an epiphyte on an older tree in the Hoh Rainforest. The dominant species in the rainforest are Sitka spruce (Picea sitchensis) and western hemlock (Tsuga heterophylla); some grow to tremendous size, reaching over 300 feet (91 m) in height and 23 ft (7.0 m) in diameter.

The green leaf area of plants and trees in the rainforest varies by about 25% as a result of seasonal changes. Leaves expand during the dry season when sunlight is at a maximum, then undergo abscission in the cloudy wet season. These changes provide a balance of carbon between photosynthesis and respiration.
