Rising temperatures and increased dryness in temperate deciduous forests have been noted in recent years as the climate changes. [13] As a result, temperate deciduous forests have been experiencing an earlier onset to spring, [16] as well as a global increase in the frequency and intensity of disturbances. [5]
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.

Extent of temperate broadleaf and mixed forests An example of temperate broadleaf and mixed forest in La Mauricie National Park, Quebec.. Temperate broadleaf and mixed forest is a temperate climate terrestrial habitat type defined by the World Wide Fund for Nature, with broadleaf tree ecoregions, and with conifer and broadleaf tree mixed coniferous forest ecoregions.
Temperate deciduous forests dominated from about 33° to 30° N. latitude, including most of the glacial Gulf Coast from about 84° W. longitude. Regional climate was similar to or slightly drier than modern conditions. Oak, hickory, chestnut, and southern pine species were abundant.
These forests stretch from eastern Texas and northern Florida to the Adirondacks and Wisconsin. For a general description of these forests, refer to Temperate Deciduous Forest. The standard reference is The Deciduous Forest of Eastern North America. [5] 52 Driftless Area (far northwestern Illinois) 52a - Savanna Section
The Eastern Temperate Forest region can thus be described as "warm, humid, and temperate" with abundant levels of precipitation year-round. There are many global patterns that affect and contribute to the climate of the Eastern Temperate Forest region, such as global ocean currents, El Nino, La Nina, the Gulf Stream current, and global air ...
The Appalachian temperate rainforest has a cool and mild climate and meets the criteria of temperate rainforests identified by Alaback. [1] Temperature and precipitation are extremely variable with elevation, with rainforest conditions usually but not always concentrated around spruce–fir forests at higher elevations.
The Ecological regions of Quebec are regions with specific types of vegetation and climates as defined by the Quebec Ministry of Forests, Wildlife and Parks. Given the size of this huge province, there is wide variation from the temperate deciduous forests of the southwest to the arctic tundra of the extreme north.
