COVID Considerations

Keeping the health of everyone in our community in mind, we’re approaching our programming with intentional steps. These steps follow CDC, Wisconsin Department of Health Services, and UW–Madison guidance. These requirements are in place to limit the spread of COVID-19.

During our upcoming events:

  • We will institute physical distancing of 6 feet
  • Participants will be reminded of hand-washing
  • We will concentrate our learning outdoors
  • You will be asked to wear a face covering

Additionally, we will be collecting contact information in the event we need to make a participant aware of potential exposure to COVID-19. Attendees who do not follow these requirements will not be able to participate. You can learn more about our policy and guidance at

Waukesha County Parks and Friends of Retzer Nature Center are hosting a week-long Master Naturalist training at Retzer Nature Center, a 400-acre county park located in Waukesha. Join us from July 26-31, 2021 for an exploration of the prairies, forests, waters, wildlife, and geology of southeast Wisconsin. The training will include limited classroom time at Retzer Nature Center and local field experiences incorporated into each day.

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 coursework in natural history, interpretation, and conservation stewardship. Trainings combine classroom instruction with field experiences and are taught by professional natural resources educators and scientists. Due to COVID-19, we anticipate the training to be held mostly in outdoor settings. Once trained, Wisconsin Master Naturalists provide 40 hours of service and take 8 hours of advanced training each year to maintain their certification and receive a recognition pin.

Our 2021 scholarships are being awarded to 2020 scholarship recipients whose trainings were canceled due to the pandemic.
