About Us

We invite you to join us for our free monthly meetings, which are open to the public and feature educational presentations. Our training classes are offered beginning each January. Requirements to become a Texas Master Naturalist are listed below.
Our Partners
We have a variety of partner organizations that we support as volunteers. Members serve as nature guides, administrative support, educators, speakers, workers, gardeners, and physical laborers. We build and maintain trails, interpret nature for visitors, weed gardens and support citizen science activities. Master Naturalists love to learn new things and are not afraid to get dirty!
