Deciduous Forests

Deciduous forest Deciduous forest is defined as a biome characterized by a tree losing leaves in the fall. I narrowed this subject a little, chose to report mainly on my temperate hardwood deciduous forests. It is dominant mainly in the eastern North America. As we all know, the leaves turn into bright red, orange and gold in autumn. Shortening the number of days in autumn makes it possible to display other beautiful colors briefly and spectacularly before the plants are stimulated to extract chlorophyll from the leaves and the leaves completely fall off and the plants become dormant for a long period of time I can do it.

Among the three basic types of temperate broad-leaved forests (temperate deciduous forests, temperate forests and temperate evergreens), our laboratory data are related to the characteristics of temperate deciduous forests. This type of forest once covered most of Eurasia, South America and North America. Like most unused forests, they were cleaned so that the land can be used for agricultural or residential purposes. Due to the glacial history, temperate deciduous forests in North America are more diverse than those in Europe. Before the ice edge retreats, glaciers fell, North America inherited the foundation of fertile soil. The type of soil is an important element and the kind of wood can prosper in one area. Common dominant species of temperate deciduous forest are beech, ash, oak, tulip, maple, birch, pecan.

Tropical deciduous forests have a mild climate with four different seasons. The annual precipitation of this forest is 75 - 125 cm. Deciduous forest forest biome changes the season by the position of the sun and the rotation of the earth. This causes the sun to warm part of the earth more than anywhere else. Many living creatures from the six kingdoms live in deciduous forests. There are oak, maple, beech and birch tree from the plant community. The fungus world mushrooms live in the forest. There are many kinds of bacteria in the Kingdom of Monera. Paramecca lives in a pond and a lake in the forest of the Protista Kingdom

Deciduous forests play important and diverse roles in the United States. Deciduous forests are estimated to cover approximately 302 million hectares, located in the eastern United States and accounting for approximately 33% of the US land area. We are harvesting many renewable resources such as wood, minerals and water from these forests. In the woods you can also enjoy various leisure activities such as fishing, hunting and hiking. In North American deciduous forests there are slight differences in the number of trees and animal species compared to the tropical rainforest biodiversity. There are only 8 to 15 trees per hectare. Unlike tropical forests, individuals of a particular species are sparsely dispersed, and certain areas of the eastern deciduous forest usually have many major species. This biome can receive annual precipitation 50 - 150 cm. Rainfall occurs mainly in the form of snow throughout the winter. Deciduous forests experience four different weather seasons, including spring, summer, autumn, and winter. The temperate deciduous forest has an average temperature of approximately 75 ° F (24 ° C or mm), but up to 86 ° F or 30 ° F (30 ° C or mm) depending on the altitude of the forest. The high mountain forests are cold. In addition to evergreen trees, deciduous forests are known for their dazzling display of discolored leaves in autumn. When leaf chlorophyll is decomposed, the color changes to red, yellow, orange. In the winter, these trees lose all leaves and play in the spring. Common tree species found in deciduous forests include conifers such as various oak, pecans, maple, beech, pine and tsugaru. Animals mainly adapt to winter through migration and hibernation. Most birds move south throughout the winter to find warm temperatures, but some mammals, such as bears, hibernate to overcome food shortages caused by the cold weather in winter.
