REEF's Citizen Science Saturday program for June is a Seagrass Monitoring Workshop organized in partnership with MarineLab Environmental Education Center.

Seagrass meadows cover much of the seafloor in the Florida Keys National Marine Sanctuary and are a vital habitat in our coral reef ecosystem. They act as a nursery and feeding grounds for animals including manatees, sea turtles, dolphins, and a variety of reef fish and invertebrates. Any significant loss of this productive habitat could result in negative impacts on the ecosystem, including reduced invertebrate and fish populations on our reefs.

Join us for a presentation by MarineLab staff about seagrass ecosystems, threats, and why it is important. MarineLab has partnered with Seagrass Watch, an international seagrass monitoring and assessment program, to conduct quarterly surveys at three permanent sites in the Florida Keys. A seagrass survey program has also been integrated into MarineLab's curriculum, and MarineLab's instructors will explain how to conduct the surveys. After the classroom lesson we will head straight to MarineLab for a short land-based survey practice and swim test, followed by a boat trip to conduct seagrass monitoring surveys while snorkeling. Afterwards, participants may join a seagrass data analysis workshop with MarineLab staff.
