Forest Types
In each forest community there are certain tree types that are the first you are likely to notice because they are the most abundant. These are called indicator
species.
Forests are often defined by their indicator species.
Soil and climate affect where certain trees will grow or won't grow
and, therefore, also help determine the forest type.
Pictured are some of the most common forest types in the United States.

Temperate
Forests  |
Long growing seasons, mild winters and
regular rainfall make North American forests some of the most
productive in the world. U.S. deciduous and evergreen
forests are in the temperate forest zone (green area of map),
which spans the Northern Hemisphere including European and Asian
forests.
Falling leaves and needles decompose and create the rich soils
of the temperate forests.
Nutrients are held in the soil of temperate forests
unlike tropical rainforests, which hold most of their nutrients
in the forest canopy.
