Present day southeast Wisconsin has a rich and varied history of land use patterns going back thousands of years. That landscape is the culmination of decisions made (and not made) that affect our land, water, flora, and fauna. Join Wehr Nature Center as we explore how we arrived at the present, and chart forward to possible futures.

Participants will explore a 400-million-year-old fossilized reef; hold a 30,000-year-old tree fragment; go behind the scenes at the School for Freshwater Sciences; learn how wildlife rehabilitation reveals our complicated history with wildlife; discover how a Milwaukee neighborhood organized and turned a cold-war missile base into a nature preserve; and see how climate change is connected to it all.

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.

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.
