Deciduous Forest
The definition of a deciduous forest is a biome characterized by the presence of trees that lose their leaves in the fall. I chose to narrow down this subject a little and do my report mainly on the Temperate Broadleaf Deciduous Forest. It is mainly dominate in eastern North America. It is very well known for its leaves which turn brilliant colors like brilliant reds, oranges and golds in autumn. The shortening of days in fall stimulates the plants to withdraw chlorophyll from their leaves, allowing a brief but spectacular showing of other beautiful colors before the leaves are shed completely and plants enter an extended period of dormacy. The temperature of the deciduous forest is associated with warmer continental and humid subtropical climates. There is about a six month growing season in this forest. The average precipitation dist
The deciduous forest biome is the home to many kinds of flowering trees. But by the early summer trees can use some of the food to create a build up of energy reserves and make seeds. The deciduous forest supports a diverse ecology. A warm growing season with abundant moisture encourages plants to grow, and the ground is covered with small plants, flowers, and grasses. Plants must find ways to ensure their survival through dormant periods, and to produce enough seeds to continue their species. However, when the chill of winter weather comes birds migrate south and some small animals hibernate. The soils are fertile, due to plenty of leaf litter. The non-growing season is do to temperature induced drought during cold winters. In summer the tall trees cast shades on the forest floor, and shade-tolerant plants grow. The long summers of this biome support many life forms, but the cold winters still provide formidable challenges. There are usually one or two strata of trees, an understory of shrubs, and low growing forbs. When spring comes the trees must draw to there reserve food to make new leaves. The forests consist of 3-5 layers, which are relatively open with rich ground flora. Some larger animals include cougars and bears.
