Pima Master Naturalists

A volunteer leadership training program designed to enhance the quality of educational, citizen science, and stewardship service participants provide to community partners. We are a chapter of the Arizona Master Naturalist Association.

Our chapter is located on Tohono O’odham, Pascua Yaqui, and Hohokam Lands. We honor them and their connection to this region. We give thanks for the opportunity to live, work, learn and gather on their traditional homeland. 

The Arizona Master Naturalist Association is committed to developing Just, Equitable, Diverse, and Inclusive programs for everyone in the state of Arizona.

Master Naturalists learn field techniques.


Want to participate in our training program? New courses are held annually from January until May. The Spring 2023 Course is full.

The application for Spring 2024 will become available on September 1, 2022. Three info sessions will be scheduled, one in September, one in October, and one in November.
