In the fields of horticulture and botany, the term deciduous (/ d ɪ ˈ s ɪ dʒ u. ə s /) [1] [2] means "falling off at maturity" [3] and "tending to fall off", [4] in reference to trees and shrubs that seasonally shed leaves, usually in the autumn; to the shedding of petals, after flowering; and to the shedding of ripe fruit.
Common ash (Fraxinus excelsior), a deciduous broad-leaved tree European larch (Larix decidua), a coniferous tree which is also deciduous. In botany, a tree is a perennial plant with an elongated stem, or trunk, usually supporting branches and leaves. In some usages, the definition of a tree may be narrower, including only woody plants with ...
Temperate deciduous forests are characterized by a variety of temperate deciduous tree species that vary based on region. [6] Most tree species present in temperate deciduous forests are broadleaf trees that lose their leaves in the fall, [8] though some coniferous trees such as pines (Pinus) are present in northern temperate deciduous forests. [6]
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.
It is one of two general types of trees, the other being a conifer, a tree with needle-like or scale-like leaves and seeds borne in woody cones. [1] Broad-leaved trees are sometimes known as hardwoods. [2] Most deciduous trees are broad-leaved [3] but some are coniferous, like larches. [4]
Hardwood is wood from angiosperm trees. These are usually found in broad-leaved temperate and tropical forests. [1] In temperate and boreal latitudes they are mostly deciduous, but in tropics and subtropics mostly evergreen. Hardwood (which comes from angiosperm trees) contrasts with softwood (which is from gymnosperm trees).
Larch trees go further north than all, reaching in North America and Siberia the tundra and polar ice. The larches are pioneer species not very demanding towards the soil and they are very long-lived trees. They live in pure or mixed forests together with other conifers or more rarely with broad-leaved trees.
