US President Ulysses S. Grant signed the Yellowstone National Park Protection Act on 1 March 1872, thereby formally creating the world’s first national park. One day earlier, on 28 February 1872, the United States Congress had approved the bill. With the President’s signature, the area was permanently designated as a national park.

The idea of Yellowstone first emerged during the 1871 expedition led by geologist Dr Ferdinand V. Hayden and his scientific team, who conducted a detailed survey of the region. Their report and photographic documentation convinced Congress that this extraordinary natural landscape should be preserved rather than opened for private ownership or settlement. On this basis, it was declared a “public park for the benefit and enjoyment of the people.”

Yellowstone National Park covers approximately 2.2 million acres, or about 8,991 square kilometres. The area spans parts of the present day states of Wyoming, Montana, and Idaho. It is home to hot springs, geysers, dense forests, mountains, rivers, and rare wildlife species. It was this unique natural beauty and scientific significance that led to the decision to protect it.

(National Park refers to an extensive natural territory within a sovereign state that is formally designated and protected through statutory law, ensuring the preservation of its ecological integrity, scenic landscapes, wildlife habitats, mountain systems, forests, wetlands, rivers, and broader environmental character.Such land is not ordinarily opened to private acquisition, speculative real estate development, housing schemes, or industrial construction. Instead, it is institutionally reserved for public benefit, ecological conservation, regulated tourism, environmental education, and scientific research, thereby safeguarding it as part of the nation’s natural heritage for present and future generations.In Pakistan, several National Parks have been established under federal and provincial legal frameworks, including Hingol National Park, Khunjerab National Park, Lal Suhanra National Park, Margalla Hills National Park, and Ayubia National Park, each representing a distinct ecological zone within the country’s environmental geography.When observing satellite imagery through platforms such as Google Earth, one often notices a prominent green demarcated expanse labeled “National Park.” This cartographic distinction signifies a legally protected landscape, formally set aside by the state in the collective public interest and for long term environmental stewardship.Syed Shayan Archive Editorial Head)

The most remarkable aspect of the legislation was that, for the first time, a country set aside such a vast tract of land not for sale, settlement, or commercial exploitation, but as a preserved public trust. It was protected so that future generations could benefit from it. This philosophy later became the foundation for land use regulation, zoning laws, and environmental protection policies.

Today, Yellowstone National Park is managed by the National Park Service, which was established in 1916 and operates under the United States Department of the Interior. In addition, scientific research and documentation have been supported by global institutions such as National Geographic, which has played a significant role in highlighting the park’s international importance.
