Where Are Deciduous Forests Found?

Temperate deciduous forests thrive in mid-latitude zones (roughly 23°–66° N/S) where four distinct seasons occur—warm summers, cold winters, and moderate precipitation (75–150 cm/year). Trees shed leaves annually to survive winter drought and cold. Major global regions include:

1. Eastern North America

The classic example. Stretches from the Atlantic Coast to the Great Plains, covering the Appalachians, Great Lakes, Ohio Valley, and Mississippi Basin. Dominant trees: oak, hickory, maple, beech, tulip poplar.

2. Europe

Extensive across Central and Eastern Europe—France, Germany, Poland, Belarus, Ukraine, western Russia. Heavily managed for centuries; remnants of primeval forest remain in Białowieża (Poland/Belarus). Dominant: beech, oak, hornbeam.

3. East Asia

Rich, diverse forests in Northeast China, Korea, Japan, and the Russian Far East. High endemism. Dominant: oak, maple, elm, linden, with unique species like Korean pine.

4. Southern South America

Valdivian and Magellanic forests of Chile and Argentina (and fringes of Brazil). Not strictly temperate deciduous—many are evergreen or mixed—but include deciduous Nothofagus (southern beech) species.

5. New Zealand

Small pockets of deciduous Nothofagus forest on the South Island, mostly in drier, eastern rain-shadow areas.

All these regions share the adaptation: leaf abscission in autumn to conserve water and energy during unfavorable seasons.
