Nature shapes us.

Now it’s our turn to shape what comes next.

A new project. A mission years in the making.

United by Nature is a national initiative bringing together knowledge, storytelling, and public participation to elevate the role of nature in the U.S.



Our work is rooted in science, guided by communities, and enriched by public participation. We’re led by a diverse, independent team of America’s top scientists, researchers, and practitioners.

Together, we’re creating a clear, accessible picture of nature across the nation and the role it plays in everything from local economies to public health and community resilience.

United by Nature is designed for people who want to act on knowledge, from local leaders to national policymakers to everyday citizens.

The work is influenced by voices across the country through dozens of public conversations. What is emerging is more than a report; it is a foundation for decision-making, collaboration, and meaningful action.

Our long-term vision is a future where nature is part of every conversation about growth, health, security, and prosperity.

The work underway will include resources for local planning and decision-making, art and storytelling to bring nature’s value to life, and a rigorous national assessment of nature’s condition and contributions.

A New Way to See the Whole Picture.

This is more than a report. It's a way to connect, contribute, and act.

With public feedback.

With practical tools.

With decisions shaped by all of us.

A shared understanding.

When we understand nature, we can shape a future where people and places thrive.



That’s why this effort brings together scientists, community leaders, and people from every corner of the country.

About us

We believe in the power of nature to connect us. Our independent team invites people across the country to contribute to what we know about nature.



Nature shapes everything we care about, from the water we drink to the security of our communities. When we understand these connections, we can make better decisions and build a future where people and places thrive.

Our work begins with a first‑of‑its‑kind national assessment of U.S. lands, waters, and wildlife, paired with tools and stories to help communities put that knowledge to work.

United by Nature is designed to evolve with input from people of all backgrounds, ensuring nature is woven into everyday decisions and shared priorities.

Phillip Levin's New York Times Op-Ed

When the first-ever independent assessment of nature in the U.S. was cut short, the team reimagined the work as “something new and more alive,” Phillip Levin wrote in an Earth Day essay for The New York Times.
