St. Croix County, Carpenter Nature Center, and The Friends of Willow River & Kinnickinnic State Parks are partnering to offer the Wisconsin Master Naturalist training. We will meet one Saturday a month, March-August, at various locations throughout the St. Croix Valley. The training will include some classroom time but will focus mostly on local and regional field experiences to exceptional sites for learning in our topic areas (geology, ecology, plant communities, wildlife, interpretation, water, and human impacts). Many regional experts will be sharing their knowledge, research, tips, and inspiration with us as they lead or present parts of the training.

The Wisconsin Master Naturalist program is a network of well-informed volunteers dedicated to conservation service, leadership, and lifelong learning. The Master Naturalist training provides 40 hours of education in a variety of natural history topics and Master Naturalist service areas. Through expert-led trainings, Master Naturalists are equipped to address challenges facing the state by making positive impacts through stewardship, citizen science, and educational activities. Trainings have an emphasis on outdoor field experiences with some classroom instruction and are taught by professional natural resources educators and scientists. Once trained, Wisconsin Master Naturalists record 40 hours of service and 8 hours of advanced training each year to maintain certification and receive a recognition pin.

Class Size



To be a certified Master Naturalist, you will be required to:

  • Attend regularly. Only four hours of training may be missed.
  • Be 18 years old or older.
  • Travel in personal vehicles as necessary to reach different learning sites throughout the training, unless transportation is provided by the host.
  • Complete a small training project.

** Master Naturalist Trainings are primarily outdoor learning experiences which may include extended periods of standing, hiking on both flat paths and off-trails with inclines, and a variety of weather conditions. If you have questions about the activity level of the training, please contact the program office prior to registering.

Financial Hardship

The Wisconsin Master Naturalist program believes that finances should not be a barrier to learning. Reduced registration fees are available for those who indicate the fee is a hardship. Reduced fees will be available during the registration process at a self-selected rate of either $200, $150, or $100. Our hope is that by participating in the Master Naturalist program you are able to give back your time to organizations that need your help. And if your financial situation changes in the future that you’ll consider a donation back to our program.
