Many of our Texas Master Naturalist Chapters are getting ready for a new crop of volunteers to join the TMN Program! Many spring courses have already started while fall and winter training seasons are being planned! We would like to share these classes through our statewide press channels. We encourage each chapter to utilize their local press, marketing avenues, and the handiest recruiting tool of all – word of mouth!
Our TMN state office is gathering information via a form below to post to our website and share with an agency news release announcing upcoming 2025 trainings. Please only fill out the form below if your chapter has an upcoming training that starts anytime in 2025.
