Great Smoky Mountains – A Fairytale World from Once Upon A Time | Free Documentary – Nature (Documentary)
The park is almost 95 percent forested, and almost 36 percent of it, 187,000 acres (76,000 ha), is estimated by the Park Service to be old growth forest with many trees that predate European settlement of the area. It is one of the largest blocks of deciduous, temperate, old growth forest in North America.
The variety of elevations, the abundant rainfall, and the presence of old growth forests give the park an unusual richness of biota. About 19,000 species of organisms are known to live in the park, and estimates as high as an additional 100,000 undocumented species may also be present.
It is also home to species of mammals such as the raccoon, bobcat, two species of fox, river otter, woodchuck, beaver, two species of squirrel, opossum, coyote, white-tailed deer, chipmunk, two species of skunk, and various species of bats.
Over 100 species of trees grow in the park. The lower region forests are dominated by deciduous leafy trees. At higher altitudes, deciduous forests give way to coniferous trees like Fraser fir. In addition, the park has over 1,400 flowering plant species and over 4,000 species of non-flowering plants.
