Mixed forest is a term used to describe an ecosystem wherein two or more tree species grow together in a particular forest habitat. There are several synonyms for mixed forest, such as temperate broadleaf and mixed forest, deciduous forest, and hardwood forest. The national forests in the eastern part of the United States are mostly comprised of deciduous mixed forests, while the boreal forests in the northern hemisphere are considered to be mixed forests. The different trees in a mixed forest create a unique environment that supports a range of flora and fauna. This type of ecosystem is highly valued for its diversity and its ability to support various forms of life.
