How to Join and Class Schedule

We appreciate your interest in the Texas Master Naturalist Program. Our mission is to develop a corps of well-informed volunteers who provide education, outreach, and service dedicated to the beneficial management of natural resources and natural areas within their communities for the State of Texas. The North Texas Chapter primarily serves Dallas, Rockwall, and Kaufman counties. The Texas Master Naturalist website provides a map and links for chapters across the state.

Learn. Volunteer. Repeat.

What does the training program cover?
