Cumberland/Ridge & Valley Mesic Forests
|
|
These hardwood forests grow in cool, protected sites where soils are deep and rich:valley floors, ravines, north-facing coves, and the bottoms of some large sinkholes. They most often occur on limestone-based soils in this ecoregion, but are sometimes found in cool, more acidic sites.
Indicator species: southern and northern sugar maples, Ohio and yellow buckeyes, tulip poplar, and basswood What's special: these forests can be lush and beautiful, especially in the spring on calcium-rich soils, when a rich diversity of spring wildflowers that are uncommon elsewhere bloom here, including celandine poppy, Virginia bluebells, bent trillium, and fern-leaf phacelia. The deep, moist soils and leaf litter support amphibians and snails. Related communities: Calcareous cliffs can be embedded within this community. Grades to Bottomlands and Floodplains. |
