Prospective Members

Application and Resources

The Heartwood Chapter holds trainings for new members once a year. Beginning in March, the classes will run through July on two Saturdays a month. This primary training is required to become a certified Texas Master Naturalist and Heartwood member, along with an initial 40 hours of approved volunteer service and an additional 8 hours of advanced training on your own.

After initial certification, the annual requirements for recertification are 40 hours of volunteer service and 8 hours of advanced training. Heartwood provides approximately one hour of advanced training at each monthly chapter meeting so that members can easily meet their advanced training requirements by attendance. For more information about Heartwood’s training series, contact the New Class Director at
