Earth Biomes
Temperate Rain Forest Regions of Earth between the tropics and the polar circles are temperate regions. Temperate regions have relatively mild cli- mates with distinct seasons.
Plants
Forests are dominated by spruce, hemlock, cedar, fir, and red- wood trees, which can grow very large and tall. Fungi, ferns, mosses, vines, and small flowering plants grow on the moist forest floor.
Animals
Animals include mosquitoes, butterflies, frogs, salamanders, woodpeckers, owls, eagles, chipmunks, raccoons, deer, elk, bears, foxes, and cougars.
Temperate deciduous forests
Temperate deciduous forests grow in tem- perate regions where winter and summer cli mates have more variation than those in temperate rain forests. These forests are the most common forest ecosystems in the United States.
Plants
Most plants, such as maples, oaks, birches, and other deciduous trees, stop growing during the winter and begin growing again in the spring.

Animals
Animals include snakes, ants, butterflies, birds, raccoons, opossums, and foxes.
Some animals, including chipmunks and bats, spend the winter in hibernation.
Over the past several hundred years, humans have cleared thousands of acres of Earth's deciduous forests for farms and cities.
Taiga
is a forest biome consisting mostly of cone-bearing evergreen trees. The taiga biome exists only in the northern hemisphere. It occupies more space on Earth's continents than any other biome.
Plants
Evergreen trees, such as spruce, pine, and fir, are thin and shed snow easily.
Tree harvesting reduces taiga habitat.
Animals
Animals include owls, mice, moose, bears, and other cold-adapted species.
Abundant insects in summer attract many birds, which migrate south in winter.
Tundra
A tundra biome is cold, dry, and treeless. Most tundra is south of the North Pole, but it also exists in mountainous areas at high altitudes.
Winters are long, dark, and freezing, sum mers are short and cool, the growing season is only 50-60 days.
Animals
Many animals hibernate or migrate south during winter. Few animals, including lem- mings, live in tundras year-round.
Plants
Plants include shallow-rooted mosses, lichens, and grasses.
Drilling for oil and gas can interrupt migra tion patterns
Grassland
Grassland biomes are areas where grasses are the dominant plants. Also called prairies. savannas, and meadows, grasslands are the world's "breadbaskets."
Animales
Larger animals include parrots, toucans, snakes, frogs, flying squirrels, fruit bats, monkeys, jaguars, and ocelots.
Plants
Few plants live on the dark forest floor. Vines climb the trunks of tall trees. Mosses, ferns, and orchids live on branches in the canopy.

Desert
Deserts are biomes that receive very little rain. They are on nearly every conti- nent and are Earth's driest ecosystems.
Animals
Animals include lizards, bats, woodpeckers, and snakes. Most animals avoid activity dur- ing the hottest parts of the day.
Plants include spiny cactus and thorny shrubs. Shallow roots absorb water quickly. Some plants have accordion-like stems that expand and store water.
Human Impact
Desert plants grow slowly. When they are damaged by people or livestock, recovery takes many years.
Tropical Rain forest
The forests that grow near the equator are called tropical rain forests. These forests receive large amounts of rain and have dense growths of tall, leafy trees.
People have cleared more than half of Earth's tropical rain for- ests for lumber, farms, and ranches. Poor soil does not support rapid growth of new trees in cleared areas.
Some organizations are working to encourage people to use less wood harvested from rain forests.
