Yellowstone’s wildlife legacy, and why preservation matters

Yellowstone’s photographs are not just about scenery. They frame a landscape that has shaped American conservation since Congress established the park on March 1, 1872, and they show why preserving it now means managing wildlife, crowds, and pressure from every direction. In America’s 250th year, Yellowstone stands as both a national emblem and a living test of whether public lands can still be protected while millions of people come to see them.

The park that changed the country

Yellowstone became the world’s first national park on March 1, 1872, created so its hydrothermal wonders would be open “for all to enjoy,” as the National Park Service puts it. Long before that federal designation, people had spent time in the Yellowstone region for more than 11,000 years, using the area as home, hunting grounds, and transportation routes. That history matters because Yellowstone is not only a scenic preserve; it is a place where human use and natural abundance have been intertwined for millennia.

Today, the park’s wildlife is part of what makes it singular. Yellowstone is home to nearly 300 bird species and 67 mammal species, a concentration that makes it one of the country’s most important large-animal viewing landscapes. The same diversity that draws visitors also makes the park vulnerable, because every encounter with wildlife can put both animals and people at risk if the rules are ignored.

How to read the landscape safely

The National Park Service is blunt about distance: stay at least 100 yards from bears, wolves, and cougars, and at least 25 yards from all other animals, including bison and elk. Those are not courtesy guidelines; they are safety rules in a place where even familiar-looking animals can be dangerous. Bison, elk, wolves, and bears do not behave like animals in a zoo, and the park’s scale can make it easy for visitors to underestimate how quickly a wild animal can close the distance.

That caution is part of preservation, too. Wildlife in Yellowstone is not a backdrop for human traffic, and the park’s popularity means every visitor has a direct role in protecting the habitat that makes the place worth visiting. When animals are repeatedly approached, stressed, or displaced, the damage extends beyond a single encounter and can alter how they move through the landscape.

Tom Murphy and the visual record of Yellowstone

Wildlife photographer Tom Murphy has spent decades building a visual archive of Yellowstone. He says he began his professional photography career in 1978 after moving to Livingston, Montana, and his biography says he has traveled extensively in Yellowstone since 1975 and has skied across the park three times. He also says he was the first person licensed to lead photography tours in Yellowstone Park, through Wilderness Photography Expeditions.

Murphy’s work has become part of the park’s interpretive fabric. He donated most of the photography displayed in the Old Faithful Visitor Education Center and the Mammoth Visitor Center for National Park Service educational use, which means his images are not just art but public-facing teaching tools. In a park as visited and mythologized as Yellowstone, those photographs help translate the scale of the place into something visitors can understand before they step onto the trail.

His images also connect Yellowstone’s beauty to its management challenges. A photograph of a wolf in Lamar Valley or a buffalo in open country can capture the drama that draws millions of people, but it also underscores how carefully that land has to be stewarded if those scenes are to remain possible.

The wolf comeback tells the larger conservation story

Yellowstone’s wolf story is one of the clearest examples of how preservation can reshape an ecosystem. Wolves were reintroduced into the park in 1995, after being nearly eliminated from the lower 48 states. The park notes that the restoration came after decades of planning and during the Endangered Species Act era, a reminder that recovery at this scale is usually measured in generations, not seasons.

That reintroduction changed more than one predator-prey dynamic. It became a national symbol of what conservation can accomplish when policy, science, and public commitment line up. Yellowstone’s reputation today rests not only on its geysers and granite views, but on the fact that a species once pushed nearly out of the continental United States now again moves through the park as part of a functioning wild system.

Millions of visits, and the cost of popularity

Yellowstone remains one of the most visited parks in the country, with the National Park Service recording 4,762,988 recreation visits in 2025. That level of demand puts pressure on roads, wildlife corridors, visitor facilities, and the people tasked with keeping animals and visitors apart. Crowds also change the experience of the park itself: seeing a bison herd or a wolf pack becomes harder when every turnout is full and every pullout feels temporary.

The long-term challenge is not simply how many people can enter the park, but how to keep that access from eroding the very thing people come to see. As visitation grows, preservation has to account for traffic, habitat fragmentation, and the broader pressures that come with development around major destinations in the Greater Yellowstone Ecosystem. Yellowstone’s future depends on keeping the landscape connected enough for wildlife to move, feed, and survive without being pushed into smaller, riskier pockets.

A bison stamp in a year of national reflection

Murphy’s Yellowstone photography also reached a national audience through the U.S. Postal Service’s American Bison Forever stamp in 2026. The stamp uses one of his photographs of a wild buffalo in Yellowstone, and the Postal Service said it honors the national mammal and its conservation comeback. It was dedicated at the Boston 2026 World Exposition and is part of USPS’s 250th-anniversary programming.

That choice is revealing. The bison is not just an icon of the West; it is a public-lands story, a wildlife recovery story, and a reminder that the American conservation project has always depended on places like Yellowstone. In the country’s 250th year, the park’s value is measured not only in views, but in what it still protects: a functioning wild landscape, a long human history, and a standard for preservation that remains hard to meet.
