Become a Certified Texas Master Naturalist™! Committed, dedicated and educated Master Naturalists are needed to preserve the natural world for the future! If not you, who? If not now, when?

Lindheimer Chapter trains a group of twenty to thirty Master Naturalists annually. The group attends classes monthly for twelve months, goes on field trips, completes a class project, and selects from more than seventy projects and opportunities to volunteer in their preferred areas of interest: birding, wildlife, geology, native plant habitats, aquatic life, butterflies, bats, among many others; many educational and fun events for adults and youth; festivals and celebrations to provide outreach. There’s also “dirt work”: trail building, wildlife and bird habitat maintenance and invasive species management and eradication – hundreds of opportunities for you to make a difference in preserving our Hill Country.

Classes are based on the Texas Master Naturalist curriculum, accompanied by dynamic expert speakers, and the curriculum is hands-on during interesting & informative field trips.

Membership in the Chapter is open to qualifying individuals regardless of socioeconomic level, race, color, age, sex, religion, disability, or national origin.
