National Parks in the United States
Overview
The National Parks of the United States are protected areas overseen by the National Park Service, an agency of the United States Department of the Interior. These parks are established by an act of the United States Congress to preserve the natural beauty, unique geological features, unusual ecosystems, and recreational opportunities of the area.
History
The concept of national parks in the United States can be traced back to the establishment of Yellowstone National Park in Wyoming, in 1872. It was the first national park not only in the U.S. but also in the world. The establishment of Yellowstone was followed by Sequoia National Park and Yosemite National Park in California, which were established in 1890.
Legislation and Administration
The National Park Service Organic Act of 1916 created the National Park Service, a federal agency within the Department of the Interior, to manage all national parks and monuments. The Act mandates the agency to "conserve the scenery and the natural and historic objects and the wild life therein and to provide for the enjoyment of the same in such manner and by such means as will leave them unimpaired for the enjoyment of future generations."
Classification
National Parks in the United States are classified into several categories: National Parks, National Monuments, National Preserves, National Historical Parks, National Historic Sites, National Battlefield Parks, National Memorials, and National Recreation Areas.
