Researchers at GTM want to maximize the potential for oysters and other shellfish to provide ecosystem services like improving water quality, providing habitat and stabilizing shorelines, while serving as a local, sustainable food source. However, the ability to harvest good oysters in our region has been declining for many years for myriad reasons. In order to understand these changes and to create an action plan to improve the health of our oysters and our waters, it is important to know how things used to be. 
Shuck and Tell is the first event in which Reserve staff will attempt to collect information about where shellfish used to be harvested, what they were like, and what changes have been observed. If you have a story or a memory about shellfish harvesting in the Guana, Tolomato or Matanzas rivers and their tributaries, please stop by the St. Augustine Lighthouse Boat Ramp on Saturday, March 7 any time between 10:00 a.m. and 2:00 p.m. If you have any questions, contact Kaitlyn Dietz at Kaitlyn.Dietz@dep.state.fl.us or call (904) 823-4500.
