Location & Abiotic Factors

Located mainly in the Eastern U.S and Canada but also found in Europe and certain places in Asia, such as Japan and China.

Abiotic Factors: Soil, Temperature, soil, sunlight, water, and air masses.

Climate of Biome

Climate & Temperature: A Temperate Deciduous Forest has a hot summer and a cold winter. The temperatures can range from -30c to 30c. The yearly average climate is about 10c. A T.D.F has four seasons, this is why they are often notable, and the leave schange color in Autumn, fall off during winter, and begin to grow back in the spring.

Precipitation: 750mm to 1,500mm of rain in a year (average)

Plant Life

Plant life & How They Adapt To The Climate

Temperate Deciduous Forests are well known for the change of color in the leaves. This is an adaption to the climate. In the summer, the leaves absorb energy and turn into a lively green color. In the fall, the tree stops the supply of water and seals of the the area between the stem and the trunk, thus the leaves can't produce chlorophyll and change colors. Finally, in winter the leaves fall off so that the tree sustains the water to regrow in spring, and start the cycle over. Plant life is often based on a three level plan. The bottom level consists of lichen, moss, and ferns. The middle level is filled with shrubs. The highest level consists of oak, birch, and magnolia.


Animal life

Animal life in a deciduous forest is very diverse. There are basic producers, consumers {all that apply: tertiary etc,}, and decomposers. As depicted in the food web, bears and owls and foxes are the only organisms that do not get eaten. Insects feed of level plants and secondary consumers, birds,skunks and opossums, feed of these primary consumers. Mice are primary consumers. All these animals, however, must adapt the the climate in order to survive, For instance, in the winter, some mammals hibernate and others migrate to survive.

Animal Adaptions: 1. Birds migrate to another location because it gets to cold for them to survive. 2. Amphibians find shelter in a hollowed out log for protection. 3. Bears hibernate to store nutrients over winter when food isn't abundant. 4. When the birds leave, the insects have enough time to repopulate 5. Squirrels and Chipmunks store food underground when food is scarce.

Competition and Predator/Prey relations

Predator/Prey Relations: 1. Cougars and/ or wolves prey on the deer. 2. Owls prey on the mice. 3. Birds prey on the insects 4. Foxes prey on mice and other small animals.

Competition: 1. Bears and cougars/wolves compete over deer and fish. 2. Opossum and skunks compete for insects and shelter.

Additional info: Symbiosis is also common in these areas. For example, an owl may live in a tree for shelter while the tree is not harmed. This is commensalism

Ecological Concerns And Additional Information

There are many concerns and/or threats to a temperate forest. One of these concerns is the increase of agriculture. The rich soil is a great source for agricultural purposes, but the problem is that most of the forest whould have to be cut down. Parasitic diseases are another concern. Acid rain and logging is also a concern.
