| Abstrakt: |
The central hardwood forests of the United States are characterized by temperate broadleaf (angiosperms) and mixed broadleaf-coniferous (angiosperm-gymnosperm) stands. They cover more than 100 million acres (40 million hectares) in all. The boundaries of the ecoregion are rather ambiguous, but the commonly accepted range occurs along transition zones or ecotones, with several other bioregions, with the northern hardwood-conifer forest forming a northern border, the eastern and southern boundaries covered by the southeastern-pine forest, and the tallgrass prairie region bordering the west. |
