Who We Are

What is natural history?

We define natural history as the “…practice of intentional, focused attentiveness and receptivity to the more-than-human world, guided by honesty and accuracy.”

Why a Natural History Institute?

Natural History is as old as humanity—there have never been people without natural history. In recent years, however, natural history has been marginalized—many academic institutions have removed or shrunken natural history curricula—and the arts and humanities have too often been wrung out of remaining natural history programs.

Our Mission

The Natural History Institute provides leadership and resources for a revitalized practice of natural history that integrates art, science, and humanities to promote the health and well-being of humans and the rest of the natural world.

About Us

The Natural History Institute engages the next generation of naturalists to reunite science, humanities, and art in the practice of natural history. We nurture hope by combining traditional observational tools and practices with modern technology and global information sharing to help people develop attitudes and skills to meaningfully connect with the natural world, and to contribute understanding and innovative solutions to the world’s most pressing environmental challenges. We provide easily accessible public programs, research facilities to document the biodiversity of the Mogollon Highlands ecoregion, and facilitate a national conversation on a renaissance of natural history generating creative ideas and proactive strategies for engagement.

You are invited to utilize the Institute as a place to collaborate on projects, share information, pursue research questions and ecological curiosities, and become inspired to better know the world around you.
