Deciduous Forest




The deciduous forest can be found in the Eastern part of North America and the middle of Europe. Some major deciduous forest are found in Russia, Japan, Eastern China, as well as South America in Chile and Paraguay, New Zeland and southern Australia.

Sunlight: Although the canopy is moderately dense, it does allow sunlight to reach the forest floor. This sunlight allows plants in the other layers to grow

Precipitation: The deciduous forest receives at least 50 cm of rain per year to support the growth of tress and plants.

Temperature: The temperature in the decidous forest varies through out the year, and has four seasons, summer, spring, winter, and fall. The temperature varies greatly through out each season. The winter can reach below freezing and the summers can reach up to the high 80's.

Climate- the Climate is a mixture of temperature and precipitation. Deciduous forests have almost 14 inches of rain in the winter months and more than 18 inches of rain in the summer.


Animal Species: Different habitats of the deciduous forerst have diffrent aniamls. During the winter seasons it is usally hard for animals to find food so the animals must adapt to situations like these. Some aniamls in the decisuous forest consist of the black bear, fox, brown bear, blue jay, raccoon, and gray squirrel.

Plants: In the deciduous forest there are many different types of trees, plants, and bushes and each if affected by the climate and animals. The trees produce thin flimsy leaves, that arent very durable and usually last 5-6 months. Some types of tree's consist of oak,birch,aspen, and maple. In the autumn the leaves turn bright colors. Colorful flowers grow on under the trees as well as fruits, and wood thrushes. Also in the deciduous forest there are five different zones, they are The Three Stratum zone, The Sapling zone, the shrub zone, the herb zone, and the ground zone. The stratum zone is a zone that contains many different types of trees such as oak, beech, maple, chestnut hickory and many others. The Sapling zone has many small trees. The shrub holds species, such as rhododendrons, azaleas, mountain laurel, and huckleberries. The fourth zone is the herb zone it contains short plants some known as herbal plants. The last zone is the ground zone it contains club mosses, and true mosses.

The American Black Bear is an animal that inhabitants the Deciduous forest. The way it fits into the food chain is it is one of the larger predators, so it’s on the top of the pyramid. The bear’s are the omnivores in the food chain. It eats as much as 30 pounds a week and hibernates between 4-7 months. This lets them save energy during the cold winter months. During there hibernation the black bear loses weight. Males can lose 15% to 30% of their weight. Females can lose almost half their body weight. In the wild the black bear can survive up to twenty-five years, and if there lucky sometimes longer.
