The Appalachian Mountains began to form 460 million years ago with the collision of tectonic plates, and finished their uplift around 230 million years ago. [11] During the Last Ice Age, ice covered much of northern North America, but the southern Appalachians remained ice-free. [ 7 ]
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.
Blue Ridge Mountains - Front Royal, Virginia Although the term "Blue Ridge" is sometimes applied exclusively to the eastern edge or front range of the Appalachian Mountains, the geological definition of the Blue Ridge province extends westward to the Ridge and Valley area, encompassing the Great Smoky Mountains, the Great Balsams, the Roans, the Blacks, and other mountain ranges.

Temperate rainforest extends through the Appalachian areas of western North Carolina , [ 9 ] southeastern Kentucky , [ 10 ] southwest Virginia ...
The Pisgah National Forest covers 512,758 acres (801 sq mi; 2,075 km 2) [9] of mountainous terrain in the southern Appalachian Mountains, including parts of the Blue Ridge Mountains and Great Balsam Mountains. Elevations reach over 6,000 feet (1,800 m) and include some of the highest mountains in the eastern United States.
In the Appalachian Mountains, the highest point of the forest is Mount Rogers, also the highest point in Virginia at 5,729 ft (1,746 m) in Mount Rogers National Recreation Area. There are 230,000 acres (93,000 ha) of old-growth forest here, and the Blue Ridge Parkway and Appalachian Trail both run through the forest. [57] Gifford Pinchot ...
The vegetation of the New England and Maritime Appalachian Highlands is similar throughout the Nova Scotia highlands including the Cobequid Hills and the Pictou-Antigonish Highlands on the mainland and the Cape Breton Highlands, the Chaleur Uplands of New Brunswick, the New England Uplands, the White Mountains and Mont Mégantic on the New ...
