This 12-week class provides a foundational education about the ecology of the lower Rio Grande Valley prior to volunteering as a Texas Master Naturalist (TMN). It is taught by local experts who are highly rated by past trainees. It’s also a delightful chance to connect with like-interested folks aged 20s to 80s from a variety of backgrounds. All are welcome! 

Texas Master Naturalist is a volunteer organization.  There is a volunteer requirement for certification as a Texas Master Naturalist with further volunteer work and additional training being expected annually to maintain active membership.
