Introduction to Pine Forest: There are very few natural wilderness areas on earth that are so pristine yet so acceptable. And in the heart of Alaska's Denali National Park, a special relationship exists between people and animals. In fact, it is a completely self-sustaining wildlife area. There are more than 35 species of animals, more than 130 species of birds and hundreds of species of plants. All this develops in accordance with nature, and the natural ecological balance has not been destroyed by the emergence of humans.
