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 coniferous and holly in cold climates, eucalyptus, Live oak, acacias and banksia in more temperate zones, and rainforest trees in tropical zones.

Species of trees[edit]

Coniferous temperate evergreen forests are most frequently dominated by species in the families. The trees include: Pinaceae and Cupressaceae. Broadleaf temperate evergreen forests include those in which Fagaceae, such as oaks and ferns are common, those in which Nothofagaceaepredominate, and the eucalyptus forests of the Southern Hemisphere. There also are assorted temperate evergreen forests dominated by other families of trees, such as Lauraceae in laurel forest.


Temperate evergreen forests, coniferous, broadleaf, and mixed, are found largely in the temperate mid-latitudes of North America, Siberia, Canada, Australia, Africa, Scandinavia, Indonesia, Malaysia, Amazon and Orinoco basins of South America, Himalayas and western ghats of India and Andaman and Nicobar Islands. Broadleaf evergreen forests occur in particular in southern China, southeastern Brazil, and parts of southeastern North America. [1] and in countries around the Mediterranean Basin, such as Lebanon and Morocco. Other examples include the wet temperate conifer forests of northwestern North America.

Tropical evergreen forests (or tropical rainforests) are usually found in areas receiving more than 234&nbs of rainfall and having a monthly mean temperature of 20 °C or higher in the coldest months. They occupy about seven percent of the Earth's surface and harbour more than half of the planet's terrestrial plants and animals. Tropical evergreen forests are dense, multi-layered, and harbour many types of plants and animals. These forests are found in the areas receiving heavy rainfall (more than 200  cm annual rainfall). They are very dense. Even the sunlight does not reach the ground. Numerous species of trees are found in these forests. In some regions, some types of trees shed their leaves at different times of the year. Therefore, these forests always appear green and are known as evergreen forests.
