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.
The Appalachian Mountains of Eastern North America are a biodiversity hotspot. [1] [2] Like other mountains, the Appalachians have high rates of endemism because they create isolated "islands" of unique habitat conditions distant from other, similar habitats.
The range is older than the other major mountain range in North America, the Rocky Mountains of the west. Some of the outcrops in the Appalachians contain rocks formed during the Precambrian era. The geologic processes that led to the formation of the Appalachian Mountains started 1.1 billion years ago.
[4] [7] The two trees can be distinguished by their needles and cones, with Fraser firs having blunt-shaped needles and upright cones and red spruces having prickly four-cornered needles and cones pointing downward. [8] The oldest red spruces are over 300 years old, and the tallest grow to over 100 feet (30 m).
Human activities increased the dispersal of edible plants, including trees, shrubs, grasses, and lianas. [ 16 ] Cultural developments accelerated with the adoption of agriculture in the highlands in the Middle Woodland period , delayed relative to the lowlands by rugged terrain, low population, limited fertile soil, and a shorter growing season ...
In southern Appalachia, growth of sycamore, walnut, and hickory trees are common. It is estimated that there is around 2,000 species of flora within the Appalachia region. Flowers vary due to elevation and climate of the area of Appalachia region. Different types of flowers in the northern and southern sections of the Appalachia.
In the early 19th century, the rift between the yeoman farmers of Appalachia and their wealthier lowland counterparts continued to grow, especially as the latter dominated most state legislatures. People in Appalachia began to feel slighted over what they considered unfair taxation methods and lack of state funding for improvements (especially ...
Thus relatively little is known about Appalachia in comparison to Laramidia, with the exception of plant life, marine life and the insects trapped in amber from New Jersey. In addition, due to a lack of interest in Appalachia, many fossils that have been found in Appalachia lie unstudied and remain in the inaccurate genera to which they were ...
