Forests where a majority of the trees lose their foliage at the end of the typical growing season are called deciduous forests. These forests are found in many areas worldwide and have distinctive ecosystems, understory growth, and soil dynamics. [20] Two distinctive types of deciduous forests are found growing around the world.
They are most commonly found in the Northern Hemisphere, with particularly large regions in eastern North America, East Asia, and a large portion of Europe, though smaller regions of temperate deciduous forests are also located in South America. Examples of trees typically growing in the Northern Hemisphere's deciduous forests include oak ...
Deciduous forests are composed mainly of broadleaf trees, such as maple and oak, that shed all their leaves during one season. [4] They are typically found in three middle-latitude regions with temperate climates characterized by a winter season and year-round precipitation: eastern North America, western Eurasia and northeastern Asia. [5]
Sprouts of chestnut (Castanea dentata) can also be found. In the northeast, eastern red-cedar (Juniperus virginiana) or hophornbeam (Ostrya virginiana) are sometimes important. In the understory, some areas have a fairly well-developed heath shrub layer, others a graminoid layer, the latter particularly common under deciduous trees such as oaks ...
Aspen trees are all native to cold regions with cool summers, in the north of the northern hemisphere, extending south at high-altitude areas such as mountains or high plains. They are all medium-sized deciduous trees reaching 15–30 m (50–100 ft) tall. In North America, the aspen is referred to as quaking aspen or trembling aspen because ...
Young tree in natural habitat American chestnut male (pollen) catkins. Castanea dentata is a rapidly-growing, large, deciduous hardwood eudicot tree. [20] A singular specimen manifest in Maine has attained a height of 115 feet (35 m) [21] Pre-blight sources give a maximum height of 100 feet (30 m) and a maximum circumference of 13 feet (4.0 m).

Trinidad and Tobago dry forest on Chacachacare showing the dry-season deciduous nature of the vegetation. Dry forests tend to exist in the drier areas north and south of the tropical rainforest belt, south or north of the subtropical deserts, generally in two bands: one between 10° and 20°N latitude and the other between 10° and 20°S latitude.
Elms are deciduous and semi-deciduous trees comprising the genus Ulmus in the family Ulmaceae.They are distributed over most of the Northern Hemisphere, inhabiting the temperate and tropical-montane regions of North America and Eurasia, presently ranging southward in the Middle East to Lebanon and Israel, [1] and across the Equator in the Far East into Indonesia.
