Forest Animals

1345 species

A forest is an area of land dominated by trees. Forests are the predominant terrestrial ecosystem of Earth and are distributed around the globe. More than half of the world's forests are found in only five countries (Brazil, Canada, China, the Russian Federation, and the United States of America). The largest share of forests (45 percent) is in the tropical latitudes, followed by those in the boreal, temperate, and subtropic domains. Forests sometimes contain many tree species within a small area (as in tropical rainforests and temperate deciduous forests), or relatively few species over large areas (e.g., taiga and arid montane coniferous forests). A forest is made up of many layers. 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. Each layer has a different set of plants and animals, depending upon the availability of sunlight, moisture, and food.
