Wolves were reintroduced to the Greater Yellowstone Ecosystem in 1995 to restore ecological balance and address issues stemming from the decline of the wolf population in the early 20th century. The absence of wolves had led to overpopulation of elk, which in turn caused overgrazing and degradation of vegetation, impacting the entire ecosystem. By reintroducing wolves, wildlife managers aimed to control elk populations, promote biodiversity, and restore natural processes within the ecosystem. This action has since led to positive ecological changes, such as improved vegetation growth and increased populations of other species.

The park is located mainly in northwestern Wyoming but small sections of the park lie in Montana and Idaho. The park is located in the Greater Yellowstone Ecosystem, the headwaters of the Yellowstone River, and Yellowstone Caldera.
Yellowstone National Park, established by the U.S. Congress and signed into law by President Ulysses S. Grant on March 1, 1872. The name actually derives from the Yellowstone River which flows some 670 miles from the heart of the Greater Yellowstone Ecosystem in Wyoming to the Montana/North Dakota border.
Over 1700 species of native plants and more than 170 invasive species inhabit Yellowstone. They include deciduous trees, wildflowers (including 12 species of orchids), conifers, brush, and grasses.
Yellowstone National Park comprises 2,219,823 acres (3,472 square miles), an area larger than the states of Rhode Island and Delaware combined. Yellowstone Park is a part of the 18-million acre Greater Yellowstone Ecosystem, the largest in-tact temperate ecosystem in the world.
Yellowstone National Park is America's first and most famous Wildlife Sanctuary, originally referred to as 'Colter's Hell'. The park itself is the centerpiece of the Greater Yellowstone Ecosystem, which is the largest (nearly intact) ecosystem in the Earth's northern temperate zone. The park is also home to the largest megafauna location in the Continental United States. Please see the related link listed below for more detailed information:

A natural ecosystem would have greater biodiversity than a human-made ecosystem. This is because in a human made ecosystem, everything is controlled and monitored, such as on a farm or in a garden. In a natural ecosystem, the plants, animals, and insects are allowed to flourish as they will, leaving greater room for naturally occurring diversity.

The caldera that covers most of Yellowstone Park was produced by a supervolcano. A supervolcano is an explosive volcano capable of producing an eruption with an ejecta volume greater than 1,000 cubic kilometers. The Yellowstone Caldera is one of the largest and most active supervolcanoes in the world.
