Abiotic factors in a deciduous forest include precipitation, wind patterns and temperature. Abiotic factors are those factors that are physical and not derived from living organisms.
Unlike tropical forests, temperate, or deciduous forests experience all four seasons. They experience large temperature variations with winter temperatures ranging between -22 and 30 degrees Fahrenheit and summer temperatures reaching as high as 90 degrees. Annual rainfall in a deciduous forest is usually between 29 and 60 inches, which is second only to the tropic regions.
A deciduous forest is a forest in which most of the trees lose their leaves each year. They are located all over the northern hemisphere in places such as Europe and North America. When the leaves fall, they begin to decompose, and fungus and bacteria take over, providing the necessary nutrients to facilitate the growth and development of new leaves in the spring. Some of the oldest trees in the world are located in deciduous forests.
Unlike grasslands, deciduous forests do not receive a lot of sunlight. That means the plants growing under the thick canopy of trees must be able to adapt to low levels of sun. Many of the plants that grow in this environment are perennial and woody shrubs like the honeysuckle and dogwood dominate the forest floor.
