Do You Know What's in the USVI Red Hook Mangroves?

The Marine Debris Action Plan (MDAP) team has been hosting annual  Great Mangrove Cleanups since 2018 at sites across the US Virgin Islands. The most recent cleanup on St. Thomas took place on April 24th, 2021 along the National Park Road in Red Hook. The event was a success, bringing together 54 members of the community and resulted  in the removal of 1,707 lbs of marine debris!

Over half of all volunteers were local students from the University of the Virgin Islands, Ivanna Eudora Kean High School, Charlotte Amalie High School, Antilles School, and Virgin Islands Montessori School & Peter Gruber International Academy. Other volunteers included community members and representatives from local businesses such as ProSolar Caribbean and Banco Popular Virgin Islands. Everyone worked together to remove marine debris such as plastic bottles, glass bottles, and beverage cans polluting the mangrove shoreline. “This is an incredible amount of debris concentrated in such a short length of mangrove shoreline. To remove that much debris in just a few hours speaks to the hard work of our volunteers,” says project lead Dr. Kristin Wilson Grimes from the UVI Center for Marine & Environmental Studies. Depicted below are some of the student volunteers and their families that participated in the cleanup (Photos: K. Edwards).
