Temperate Deciduous Forest

Location and Climate:

Temperate deciduous forests can be found in the eastern part of the United States and Canada, most of Europe, and parts of China and Japan. 

 This biome has four distinct seasons. This includes spring, summer, fall, and winter. In summer the temperature is hot and in the winters the weather is generally cold.  The average temperature is around -30 degrees celsius and up to 30 degrees celsius. There is percipatation year round; 750 mm to 1,500 mm per year.

Physical Features:

Temperate deciduous forests are generally non-flat and many lay on mountain chains or regions where it is mountainous. Many are or relatively adjacent to coastal waters.

Plant Life:

There is a large variety of plant life in a temperate deciduous forest. Lichen, moss, ferns, wildflowers, and other plants can be found of floors of temperate deciduous forests. Shrubs fill the middle layer. Most of the trees are broadleaf trees such as oak, maple, beech, hickory and chestnut. Most plants tend to go through a period called dormancy (or sleep) in the winter. The term deciduous refers to how a tree sheds its leaves. Leaves change colors during the fall and eventually just fall off. The leaves grow back in the spring.

Leaves changing color. Can be a shade of red, orange, or yellow.

Trees in the winter.

Trees changing from green to various colors in the fall.

 Animal Life:

Animals that live in temperate deciduous forests have to be able to adapt to both the heat and the cold during the winter and summer months. Many mammals (such as chipmunks,squirrels, and bears) will hibernate during the winter months to survive. Typical animals in this biome include many types of insects, spiders, salamanders, turtles, and frogs. Birds like hawks, owls, cardinals, and woodpeckers are common. Mammals include things like raccoons, bears, deer, porcupines, and foxes.

 Human Influence/Health Concerns/Threats:

The biggest threat to this biome is development of cities and agriculture because many people seek to live in these areas do to its temperature (neither too hot nor too cold) and the soil is rich so farming is very easy. Also, there are no disease spreading insects unlike the tropical forests regions. Another threat is logging; most trees here are hardwoods, meaning that they have a much more denser wood than other trees. Acid rain is also a threat because it kills off many trees and animals. Global warming also affects these forests because it can change rainfall patterns.

Many trees die due to acid rain and its effects.
