Native Oak Tree Ranges in the United States

Oak is a tree in the genus Quercus of the beech family (Fagaceae).

The genus Quercus is native to the Northern Hemisphere and covers evergreen and deciduous species spreading from cold temperate to tropical latitudes in the Americas, Europe, Asia, and North Africa. North America contains the most significant number of oak species, with around 90 growing in the U.S., while Mexico has 160 species, of which 109 are endemic. The second most significant center of oak diversity is China, which includes almost 100 species.

The map below sums up the whole of oak species growing in each region of the United States.

The highest biodiversity of oak species occurs in the eastern United States. White oak (Quercus alba) is one of the most common oak species in almost all U.S. Eastern states and one of the most common tree species in the United States.

Oaks do not grow in the central west of the United States. But there are fossil oaks discovered all over the territory of southern Idaho, eastern Oregon, and Nevada. This area had a diverse mixed forest 25 million years ago when this territory was less arid.

Oaks evolved at high latitudes as a much warmer climate period and were shifted to southern latitudes as the climate cooled during the Tertiary period. The western and eastern North American oak biodiversity represents isolated evolutionary lineages that took divergent ways, separated by the Rocky Mountains.

Oak diversity in Canada is comparatively low (it can be effortlessly extrapolated from the map above). Oak biodiversity is exceptionally high in some parts of Mexico, particularly the Sierra Madre Oriental. Those oak species in Mexico oak relate to the Eastern North American oak lineages.
