When Virgin Islands students participate in Mangroves in the Classroom this school year, they will do more than read about invasive species. Using lionfish collected from local waters, students will examine fish anatomy, make scientific observations and explore how invasive species affect the marine ecosystems surrounding their communities.
The hands-on lesson is part of Mangroves in the Classroom (MIC), a place-based education program led by the University of the Virgin Islands’ Growing, Research, Restoration, Outreach and Education (GRROE) USVI Mangroves Program within the Center for Marine and Environmental Studies (CMES), in partnership with the Virgin Islands Department of Education.
Since 2022, MIC has provided hands-on environmental education to more than 2,000 students across the U.S. Virgin Islands. Through classroom lessons and field experiences, students explore mangrove ecology, biodiversity, restoration, climate resilience and coastal stewardship.
One of the program’s signature experiences will return during the 2026–2027 school year through UVI’s continued collaboration with The CORE Foundation.
Based in the U.S. Virgin Islands, The CORE Foundation is a marine-focused nonprofit organization that leads coastal education and coral restoration initiatives. The organization is best known locally for managing the Caribbean Lionfish Response Program, which works to reduce invasive lionfish populations and protect native reef ecosystems.
Lionfish collected during the Foundation’s annual St. Thomas, St. John and Water Island Lionfish Derby will be incorporated into classroom lessons about invasive species and their effects on Caribbean marine ecosystems.
The CORE Foundation’s 2026 Lionfish Derby brought together divers from St. Thomas, St. Croix and St. John, who removed 241 invasive lionfish from Virgin Islands waters.
Native to the Indo-Pacific region, lionfish have become established throughout the Caribbean. They pose a significant threat to reef ecosystems by preying on native reef fish that perform important ecological functions, including controlling algae, producing sand, removing parasites and supporting healthy coral reef communities.
During guided dissections, students will use scientific tools to examine the donated lionfish, study fish anatomy and investigate the ecological effects of invasive species. The lesson also encourages students to think critically about ecosystem balance and the connections among coral reefs, seagrass beds and mangrove forests.
“This is consistently one of our most popular lessons with both students and teachers because it brings science to life,” said Laura Bloem, education and outreach coordinator for GRROE USVI Mangroves. “The lionfish are collected right here in Virgin Islands waters, so students immediately see the relevance to their own community. During the dissections, they use scientific tools, make observations and investigate the impacts of invasive species while learning about the ecosystems that surround them every day.”
For The CORE Foundation, the collaboration provides another way to turn community conservation efforts into meaningful educational opportunities.
“Education is one of the most important tools we have for protecting the Virgin Islands’ marine ecosystems,” said Matthew Sims, education coordinator for The CORE Foundation. “Through our Lionfish Derby, we’re able to remove an invasive species while also giving students a hands-on opportunity to explore the connections between mangroves, coral reefs and the open ocean. We’re proud to partner with UVI’s Mangroves in the Classroom program to help inspire the next generation of environmental stewards.”
As the new school year begins, Mangroves in the Classroom welcomes opportunities to partner with additional Virgin Islands public schools. Teachers interested in participating during the 2026–2027 school year are encouraged to contact the GRROE USVI Mangroves team to learn more about available classroom lessons, field experiences and restoration opportunities.
UVI and the Mangroves in the Classroom program extend their gratitude to The CORE Foundation, derby participants, volunteers and sponsors for their continued commitment to marine conservation and environmental education.
By transforming lionfish removed from Virgin Islands waters into classroom learning tools, the partnership gives students an opportunity to investigate a local environmental challenge firsthand—and to see themselves as scientists and stewards of the ecosystems they call home.
