The Southeastern mixed forests are an ecoregion of the temperate broadleaf and mixed forest biome, in the lower portion of the Eastern United States.
This ecoregion covers the Piedmont region of the eastern United States, stretching in a broad arc from extreme southwest New Jersey southwest to Mississippi. It is distinguished from neighboring ecoregions by elevation and vegetation. At lower elevations to the east are the Middle Atlantic coastal forests on the Atlantic coastal plain. Similarly, the Southeastern conifer forests occupy the Gulf coastal plain to the south. Higher, and to the north and west, are the Appalachian-Blue Ridge forests and the Appalachian mixed mesophytic forests of the Appalachian Mountains.
This ecoregion lies within the Cfa Köppen climate zones, and the Cf and Do Trewartha climate zones, placing it in the humid subtropical, and in its northernmost extreme, the temperate oceanic climate categories, with warm summers, a coldest month mean temperature at or above freezing, and significant precipitation in all seasons.
Both oaks (Quercus spp.) and hickories (Carya spp.) are abundant in this ecoregion. Additionally, some 3,635 species of native herbaceous and shrub species have been recorded here.
