USA Coastal Plains, and the Southeastern USA Plains. The state is further divided into seven subregions: the Arkansas Valley, Boston Mountains, Mississippi Alluvial Plain, Mississippi Valley Loess Plain, Ozark Highlands, Ouachita Mountains, and the South Central Plains. A 2010 United States Forest Service survey determined of Arkansas's land is forestland, or 56% of the state's total area. Dominant species in Arkansas's forests include Quercus (oak), Carya (hickory), Pinus echinata (shortleaf pine) and Pinus taeda (loblolly pine). Arkansas's plant life varies with its climate and elevation. The pine belt stretching from the Arkansas delta to Texas consists of dense oak-hickory-pine growth. Lumbering and paper milling activity is active throughout the region. In eastern Arkansas, one can find Taxodium (cypress), Quercus nigra (water oaks), and hickories with their roots submerged in the Mississippi Valley bayous indicative of the deep south. Nearby Crowley's Ridge is the only home of the tulip tree in the state, and generally hosts more northeastern plant life such as the beech tree. The northwestern highlands are covered in an oak-hickory mixture, with Ozark white cedars, cornus (dogwoods), and Cercis canadensis (redbuds) also present. The higher peaks in the Arkansas River Valley play host to scores of ferns, including the Woodsia scopulina and Adiantum (maidenhair fern) on Mount Magazine. Arkansas wildlife is famous for the white-tailed deer, elk, and bald eagle. The white-tailed deer is the official state mammal. Climate Arkansas generally has a humid subtropical climate. While not bordering the Gulf of Mexico, Arkansas, is still close enough to the warm, large body of water for it to influence the weather in the state.
