ST. JOHN — The Hawksbill Turtle Project commenced its second survey of hawksbill turtles near St. John on July 1, aiming to gather crucial data on this critically endangered species.

Last year’s survey recorded 17 hawksbill turtles over two weeks of research conducted in June and July of 2023. This year, the project aims to re-encounter some of these turtles to assess their growth and identify new individuals in the area.

“Last year, we observed three turtles at this site and managed to capture two. We’re eager to see the ones we missed and re-examine those we caught,” said Scott Eanes, founder of the project, during the first research day near Cruz Bay. Eanes emphasized the importance of capturing biometric data from the young turtles to compare their growth and other metrics over the past year.

In addition to biometric data, researchers are collecting genetic information to determine the turtles’ geographic origins. This year, the project will also mark turtles with satellite tags to track their migratory patterns and gather more comprehensive data on their movements and origins.

Eanes described the research process as “more invasive but more rewarding,” noting that capturing and sampling each turtle takes about an hour. Despite the physically demanding nature of the work, which involves extensive free diving and sample collection, Eanes highlighted the importance of the data for understanding and protecting the species. Hawksbill turtles are vital to coral reef health, as they help maintain the ecosystem by removing prey from the reef surface, which in turn facilitates fish feeding.

Dr. Alex Webb, another researcher with the project, pointed out the unique challenges of their work. “In-water research is physically tougher and less common than nesting research,” he said. The Hawksbill Turtle Project, founded in 2022 and based in the U.K., supports smaller projects and conducts its own research to aid in species conservation. In 2022, the project raised $12,000 to support Ocean Spirits and the University of the Virgin Islands Sea Turtle Research and Conservation in conducting the first in-water assessment of turtles near Carriacou. This study provides a baseline for local authorities to make informed conservation decisions.

Despite the longstanding ban on hunting endangered turtles in many Caribbean countries, the effects of historical poaching are still evident today, significantly reducing hawksbill populations. “Historical records show hawksbills being taken from St. Thomas as early as 1690, which has contributed to their current scarcity,” Eanes explained. The project aims to create comprehensive data sets to inform future conservation efforts.

Community support is crucial for the project’s success, Eanes noted. Friends of Virgin Islands National Park have funded 60% of the project, while local businesses like Love City Lofts, Concordia Eco Resort, and The Tap Room have provided housing and financial support for the researchers.

Residents can contribute to the study by photographing hawksbill turtles near St. John and sending the images to the research team. “Community involvement is vital, and everyone loves turtles, making it an easy cause to support,” Eanes added.
