Why Join the Master Naturalist Program?


The mission of the Texas Master Naturalist Program is to develop a corps of well-informed volunteers to provide education, outreach, and service dedicated to the beneficial management of natural resources and natural areas within their communities for the State of Texas. There are numerous reasons why becoming a Master Naturalist is a good idea.
1. Local Knowledge
The Texas Master Naturalist program covers a range of topics relatable across the state. However, local knowledge is stressed through the selection of local experts to instruct sections of the course. Most of the course sections have a lecture and field lab component, so participants learn about and experience the local ecosystems firsthand. The vast majority of participants learn interesting facts about ecosystems in their backyard and share that information with many other people.
2. Environmental Education
Through the Master Naturalist training, participants not only learn about natural resources, but they also receive training on how to educate others about natural resources. A primary goal of the Master Naturalist program is to develop an organization of knowledgeable volunteers to help promote conservation and management of natural resources through educating their communities.
3. Continuous Learning
The Master Naturalist program and partners offer many advanced training opportunities throughout the year. These opportunities serve as more focused trainings on many aspects of the basic course or cover topics not included in the basic training. Thereby, continually increasing the participant’s knowledge.
4. Networking
The selected instructors and program partners are well respected individuals and entities in the environmental field. Through the Master Naturalist program, participants get to meet, mingle, learn from and pick the brains of these environmental leaders. Often, the Master Naturalist participants connect with one or more of the program partners for opportunities outside of the program.
5. Credentials
Who doesn’t want to be able to put “Certified Master Naturalist” on their resume? Participation in this program and its associated certification often leads to participants being recognized as environmental experts and/or leaders in their communities.
What does it take to be a Texas Master Naturalist?
Texas Master Naturalists not only get their feet wet and their hands dirty, but while doing so, they spend time in a natural setting. Members learn about different plant and animal species, and maybe even find something new: one member, in fact, discovered a new plant species.
To become a Texas Master Naturalist, each volunteer:
- Master Naturalist Trainees must successfully complete an approved training program with at least 40 hours of combined field and classroom instruction though a Texas Master Naturalist Chapter.
- After completing the training above, the candidate donates at least 40 hours of volunteer service back to the state and community. Trainees can complete their 40 hours of volunteer service and 8 hours of advanced training within a year after completion of their initial training.
- In subsequent years, the candidate must complete another 8 hours of advanced training and donate 40 hours of volunteer service to maintain their certification (or to re-certify) as a Texas Master Naturalist.
