Estimate abundance Rip rap shoreline, add fill; build mangrove planters and replant maritime hammock. Estimate size distribution Determine population origin Document the prevalence of disease Diet

12 Sea Turtle Research in the Lake Worth Lagoon Primarily juvenile green turtles Average of 22.5 turtles/km 2 Highest density of turtles in Eastern Florida Rip rap shoreline, add fill; build mangrove planters and replant maritime hammock. Average of 33 cm in length (juveniles) ~70% of turtles showed signs of fibropapillomatosis Turtles came from natal beaches in Florida, Mexico, Costa Rica and Cuba
