Nature is everywhere. Enjoy exploring the puzzles & complexities of nature at the Oslo Riverfront Conservation Area & on this website. You will find some of the plants, insects, and animals that you see here in your yard, along the roadsides, and elsewhere.
Enjoy nature everywhere.
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”.
You can check out the 2020 schedule: 2020 FMEL Volunteer Class Schedule
