Biomes of America

Describes the different biomes of America. Might be interesting to look into since most people will want to know the different biomes.

There are numerous ways to identify biomes. We identify eight biomes, even though there are some scientists that consider more than that, or less than that. The United States of America contains about five biomes out of the eight. The five biomes of the United States are Tundra, Temperate Deciduous Forest, Grassland, Taiga, and Desert.

The Tundra is the northernmost land biome in America, and on Earth. The word tundra comes from the Sami language, and it means “treeless plain.” It is a nearly treeless biome. Only a few stunted trees survive here. The dominant plants are mosses, lichens, and grasses. Many animals migrate here during the summers to feed on the plants that grow here. A numerous amount of birds spend their summers here because of the hot weather, and when it gets cold here, they migrate south. The tundra is underlain by permafrost. Permafrost means frozen soil. During the summer the ground softens to a depth of a few centimeters and becomes soggy and wet. During the winter it refreezes all over again. This damages the roots of the plants, which is why they are stunted.

Temperate Deciduous forests are characterized by changing seasons and leaf fall. These are forests mostly of oak, maple, beech, and birch; these are deciduous trees. The term deciduous means that their leaves fall in the autumn. Because of the fact that the trees are deciduous, this biome goes through striking seasonal changes. In the spring, many flowers grow rapidly, flower and bear fruit, because they don’t have much time before the trees shade them all over again. Some of the more dominant animals are deer, moose, gray foxes, chipmunks, raccoons, opossums, and squirrels, and an enormous variety of birds. The forest ground contains mucus, making it a good farmland.

Grasslands are vast areas covered with grasses and small leafy plants. The average rainfall is twenty-five to seventy-five centimeters per year, making rainfall a significant matter here. Grasslands are characterized by hot summers and cold winters. The grasslands cannot become forests because of the grazing of large animals and periodic fires. If properly treated, the deep, rich soils of temperate grasslands can support farming for years to come.

South of the tundra is a biome dominated by coniferous, or cone bearing, forests. This biome is called the taiga. The word taiga comes from the Sami language, and it means primeval forest. It rises to the higher elevations of many mountain ranges in the United States, like the Rocky Mountains, and the Appalachian Mountains. Coniferous forests are home to the giant redwoods; these trees are some of the tallest in the world. They can reach heights of more than 60 meters. The taiga winters are cold, and the summers are mild. Mild enough to allow many plants and animals to reproduce. The Taiga ground thaws when it is warm. Some of the more dominant animals of the taiga are black bears, grizzlies, wolves, moose, elk, and numerous other animals such as grouse, wolverines and voles.
