The National Park Service, nonprofit partner Yellowstone Forever and Blackstone Infrastructure's Tallgrass have created a permanent fund aimed at research, visitor infrastructure and expanded access for Wyoming communities.

What travelers need to know
- What happened: The National Park Service, Yellowstone Forever and Blackstone Infrastructure portfolio company Tallgrass announced a $105 million Conservation and Stewardship Fund for Yellowstone National Park.
- Who's affected: Park researchers, visitors relying on park infrastructure, and Wyoming students and community members who will gain new access programs.
- Where: Yellowstone National Park, headquartered at Mammoth Hot Springs, Wyoming.
- When: Announced .
- What to do: No immediate visitor action required; the fund is structured as a long-term, permanent source of support rather than a short-term grant program.
The National Park Service said Monday it has joined with its official nonprofit partner Yellowstone Forever and Tallgrass, a Blackstone Infrastructure portfolio company, to launch a $105 million fund meant to provide lasting financial support for Yellowstone National Park. The announcement, made from the park's Mammoth Hot Springs headquarters in Wyoming, frames the money as a permanent funding source rather than a one-time donation.
Interior Secretary Doug Burgum tied the gift to the park's history, invoking Theodore Roosevelt's role in laying the cornerstone of Yellowstone's gateway arch more than 120 years ago. "This historic $105 million investment honors that legacy, bringing together the best of American enterprise and conservation to expand access to Yellowstone and inspire the next generation to experience America's great outdoors," Burgum said, according to the National Park Service. He credited Blackstone, Tallgrass and Yellowstone Forever for what he called an extraordinary commitment to the park.

Three priorities for the money
The National Park Service outlined three areas the fund is intended to support over the long term:
- Conservation and research — expanding the scope and impact of Yellowstone's scientific work.
- Visitor access and experience — funding infrastructure investments inside the park.
- Community and student engagement — creating new ways for Wyoming residents, especially students, to experience Yellowstone.
That third priority will take shape as the Tallgrass WYld Yellowstone Initiative, a program named for Tallgrass, the Wyoming-based energy infrastructure company that has operated in the state for more than a decade. The National Park Service did not detail specific projects, timelines or dollar breakdowns across the three priorities in its announcement.
Blackstone frames infrastructure money as conservation tool
Sean Klimczak, Blackstone's Global Head of Infrastructure, cast the gift as consistent with the firm's broader investment philosophy. "Yellowstone is one of America's great natural treasures, and we feel a profound sense of responsibility to protect it for future generations," Klimczak said in the National Park Service's release. "This historic gift reflects our belief that infrastructure investment can and should be a force for good, helping us invest in Yellowstone's future and the growth of the communities that surround it."
The arrangement adds a private-infrastructure investor to the roster of corporate and philanthropic partners that fund Yellowstone through Yellowstone Forever, the park's designated nonprofit fundraising arm. Yellowstone, established in 1872 as the world's first national park, draws millions of visitors annually to sites spanning Wyoming, Montana and Idaho, and has long relied on a mix of federal appropriations and private philanthropy to cover costs beyond its base budget.

The National Park Service's announcement did not specify a payment schedule for the $105 million or say when the first projects funded through the new pool would begin. Further details on the Tallgrass WYld Yellowstone Initiative, including how Wyoming students and community members will apply for or access its programs, have not yet been released.
