And when it did that by passing the Yellowstone Gateway Protection Act, it protected the world's first national park from the immediate threat of two gold mining companies, one of which proposed gold mining in Emigrant Gulch in Paradise Valley and the other on Crevice Mountain next to the park.

Yellowstone is protected through a multi-layered conservation strategy managed by the National Park Service (NPS) and supported by organizations like Yellowstone Forever. In 2026, protection focuses on "Large Landscape Conservation," which ensures wildlife like grizzly bears and bison can migrate safely beyond park borders into the Greater Yellowstone Ecosystem. Technological advancements have introduced "Virtual Fencing" and AI-driven monitoring to track invasive species, such as lake trout in Yellowstone Lake, which threaten native Cutthroat trout. Additionally, the park uses a "managed wildfire" policy, allowing natural lightning-caused fires to burn when safe, which helps maintain the forest's ecological health. Stricter visitor management systems, including reservation-based entry for certain high-traffic areas and expanded "Shuttle-only" zones, help reduce the environmental footprint of the millions of tourists who visit annually, protecting the delicate geothermal features from human interference.
