The Florida Medical Entomology Laboratory (FMEL) will offer its twenty-fourth Volunteer Nature Stewardship Class for the Oslo Riverfront Conservation Area(ORCA) in January 2021. How this course will be offered – live, virtual, or some combo thereof – remains uncertain due to coronavirus.
It will provide a foundation for understanding — and enjoying — the common habitats of Indian River County and what you may find in your yard. Field activities definitely will be included.
Class participants will be asked to “volunteer back” and share what they have learned at the ORCA, another nature preserve, a nature center, or another venue. You craft how and where you “volunteer back”.
Nature is everywhere … Enhance your understanding of the plants, insects, animals & complex interactions by reading about the ORCA & other natural areas.
