Coniferous forest biome

Coniferous forest biome
                Coniferous forest ecosystems are found in regions of the Earth that experience somewhat long and cold winters, with summer being much shorter. Thus, it is no surprise that these biomes are more common the closer one travels towards the Earth’s poles. Additionally, this biome is found high atop mountains where temperatures tend to be lower and winter tends to last longer.
             
The Coniferous Forest is a forest of Conifers. A Conifer is a tree that produces its seeds in cones.  The Pine tree is the most common example.  Conifer leaves conserve water with the thick, waxy layer that covers their leaves, also known as needles.  The vegitation in the Coniferous forest is small in size, but large enough to feed the vast herbivore population.  Most of these animals survive the brutal winters by migrating or hibernating. 
                       
Average Annual Rainfall- 14-29.5 in.
Average Temperatures in the Summer- 57.2°F
Average Temperatures in the Winter- 14°F
Temperate coniferous forest         

Temperate coniferous forest is a terrestrial biome found in temperate regions of the world with warm summers and cool winters and adequate rainfall to sustain a forest. In most temperate coniferous forests, evergreen conifers predominate, while some are a mix of conifers and broad leaf evergreen trees and/or broad leaf deciduous trees. . Coniferous forests can be found in the United States, Canada, Europe, and Asia. Many species of trees inhabit these forests including cedar, cypress, douglas-fir,pine, podocarpus, spruce, redwood and yew. The understory also contains a wide variety of herbaceous and shrub species.
