GTM Research Reserve volunteer Ron Ceryak will guide hikers through Flagler County’s “River to Sea Preserve” coastal hammock to the Matanzas River along a 1.2-mile trail. Learn about nature’s bountiful vegetation and observe signs of wildlife. Hear tales of Native American lore, including how they used indigenous plants for food and medicine. Trail Guide Ron Ceryak is a retired hydrogeologist formerly with Suwannee River Water Management District for thirty years. He is now volunteering with the Guana Tolomato Matanzas National Estuarine Research Reserve (GTM NERR) at the Marineland field station. Meet the guide in the parking lot of the River to Sea Preserve.
