While the fossil sites from the southern part in Appalachia, places like Alabama and the Carolinas, have a very scant amount of Cretaceous plant fossils with the exception of Georgia, the northern parts of Appalachia, such as New Jersey, Maryland, and Delaware have a much better record in terms of plant species being unearthed there, especially ...
In terms of biodiversity, the only comparable temperate deciduous forest regions in the world are in central China, Japan, and in the Caucasus Mountains.Both the Appalachians (along with the neighbouring Appalachian mixed mesophytic forests ecoregion) and central China contain relict habitats of an ancient forest that was once widespread over the Northern Hemisphere.
Shortleaf pine is generally found in warmer habitats and at lower elevations than the other species. All the species listed do best in open or lightly shaded habitats, although white pine also thrives in shady coves, valleys, and on floodplains. The Appalachians are characterized by a wealth of large, beautiful deciduous broadleaf (hardwood) trees.

The US uses the term Appalachian Highlands, and Canada uses the term Appalachian Uplands, to define contiguous regions that have similar geology, topography, history, and native plant and animal communities. (The Appalachian Mountains are not synonymous with the Appalachian Plateau, which is one of the provinces of the Appalachian Highlands).
Since the late 20th century, tourism and second-home developments have assumed an increasingly major role. Appalachia has many different economic sectors, from aerospace and defense industries in the Greater Huntsville area in the southern part of Appalachia to tourism in many areas such as the Great Smokey Mountains and the Blue Ridge Parkway.
These forests are known for their rich diversity of plants and animals, which is due to several contributing factors, especially that the area was an unglaciated refugium for many species. It shares species with the high elevation Appalachian-Blue Ridge forests to the east, the hardwood forests to the west, and the mixed hardwood/ conifer ...
Invasive species pose a significant risk to the landscape of the Appalachian temperate rainforest, with two major introduction events in living memory. First, the chestnut blight emerged in Appalachia in the early 20th century, decimating American chestnut trees, a dominant species in the region. [18]
