Deciduous forestvegetation composed primarily of broad-leaved trees that shed all their leaves during one season. Deciduous forest is found in three middle-latitude regions with a temperate climate characterized by a winter season and year-round precipitation: eastern North Americawestern Eurasia, and northeastern Asia. Deciduous forest also extends into more arid regions along stream banks and around bodies of water.
The natural Earth is made up of numerous biomesor areas defined by regional plant and animal life. Each biome is dependent on a number of factors that determine how the local flora and fauna adapts over time. Deciduous forests are biomes that are classified by the seasonal weather patterns they experience — in that they go through all four seasons, with trees losing their leaves each fall and winter.
These forests are dominated by broad-leafed trees that shed their leaves annually deciduouswith evergreen cone-bearing seed plants conifers such as pines and hemlocks common in some areas. For thousands of years its unbroken expanse was dominated by oaks, chestnutsand hickories that provided valuable food and shelter for wildlife. The 18th and 19th centuries brought unprecedented changes as forest was cleared for agriculture, timber, fuelwood, and urban expansion.
Deciduous Forest The mid-latitude deciduous forest biome is located between the polar regions and the tropics. Because of its location, air masses from both the cold polar region and the warm tropical region contribute to the changes of climate in this biome. Mid-latitude deciduous forests have both a warm and a cold season see climograph.
A Wisconsin forest. About million years ago, during the Silurian Period, ancient plants and arthropods began to occupy the land. Over the millions of years that followed, these land colonizers developed and adapted to their new habitat.
Not every region of the world experiences a change in seasons like the temperate deciduous forests. Some are always blanketed in ice, while others have warm sunshine year round. For those of us who live in temperate regions, seasonal changes happen every few months.
The temperate deciduous broadleaf forest TDBF is composed of broad-leaf angiosperm trees like the oaks, maples, and beeches familiar to many Americans and Europeans. The forests exist best in moderate climates that are neither too hot nor too cold and neither too wet nor too dry. While there are roughly thirty families and sixty-five genera in the TDBF, variation in the precise definition and defined area of the forest make absolute numbers impossible.
Temperate deciduous or temperate broad-leaf forests are a variety of temperate forest dominated by trees that lose their leaves each year. They are found in areas with warm moist summers and cool winters. Smaller areas occur in Australasia and southern South America.
Globally, forest composition and distribution are influenced by precipitation and temperature. Soil, landform, and historical factors for example, glaciationnatural and human disturbance influence forest structure and composition on a local scale. Forests are generally absent from areas of low or strongly seasonal precipitation, including dry zones at the west side of continents and interior continental regions where annual precipitation is less than.
Deciduous forests can be found in the eastern half of North America, and the middle of Europe. There are many deciduous forests in Asia. Some of the major areas that they are in are southwest Russia, Japan, and eastern China. South America has two big areas of deciduous forests in southern Chile and Middle East coast of Paraguay.
