How Many People Can the Greater Yellowstone Ecosystem Support?

The Greater Yellowstone Ecosystem (GYE)—encompassing Yellowstone National Park and surrounding national forests and wilderness areas—is one of the largest nearly intact temperate ecosystems on Earth. Current estimates suggest it could support a human population of 2.2 to 3 million people by 2050.

Current vs. Projected Population

Currently, about 1 million people reside in the GYE region. However, rapid population growth driven by amenity migration (people moving for quality of life, recreation, and scenery) is pushing toward the 2050 projection.

Ecological Implications

This growth strains the ecosystem's carrying capacity:

• Resource Competition: Increased demand for water, land, and energy.
• Human-Wildlife Conflict: Habitat fragmentation threatens iconic species like grizzly bears, wolves, elk, bison, and native trout.
• Ecosystem Integrity: Development disrupts migration corridors and degrades water quality.

Sustainable Management Strategies

To protect the GYE, experts recommend:

• Concentrating development in compact, existing communities (smart growth).
• Permanently protecting open space and wildlife corridors through conservation easements.
• Investing in water conservation and sustainable infrastructure.
• Educating residents and visitors on coexistence with wildlife.

Balancing human needs with the preservation of this globally significant ecosystem is the defining challenge for the region's future.
