The Florida Medical Entomology Laboratory (FMEL) will offer its twenty-fourth Volunteer Nature Stewardship Class for the Oslo Riverfront Conservation Area (ORCA) in 2023 after a 2-year hiatus due to covid. This 6-session class will provide a foundation for understanding — and enjoying — the common habitats of Indian River County and what you may find in your yard. Each session will include outdoor activities..
Class participants are asked to “volunteer back” and share what they have learned at the ORCA, another nature preserve, a nature center, or in another venue. You craft how and where you “volunteer back”.
The class tentatively is scheduled to begin on Saturday, December 3, 2002 and in 2023 on Saturdays January 14 & 28, February 11 & 25, and March 4. Check back for the scheduled speakers/topics.
Please email Janice Broda at jbroda@ufl.edu if you are interested in participating in the 2023 class.
