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 distributed evenly throughout a year is about 20 to 60 inches . The non-growing season is do to temperature induced drought during cold winters. The summers are warm. The deciduous forest has four definite seasons. The long summers of this biome support many life forms, but the cold winters still provide formidable challenges. The cold weather and scarcity of food test the endurance of the animals. Plants must find ways to ensure their survival through dormant periods, and to produce enough seeds to continue their species. 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. In summer the tall trees cast shades on the forest floor, and shade-tolerant plants grow. There are only open areas in which grasses grow without sunshine in this forest on occasion. Ferns and wild flowers are abundant, and there are also many deciduous shrubs, such as some berry bushes. The deciduous forest biome is the home to many kinds of flowering trees.
