Deforestation of Mangroves in Bimini and Danger to Marine Environment


The Bahamas Weekly reports on the drastic effects of development in Bimini. The article states that research from a long-term study has revealed that the mega-resort construction in Bimini deforested almost half of a lagoon’s mangrove shorelines, affecting the delicate ecosystems, and lowering the survival rate of newborn lemon sharks to only 26%.  Marine biologist Dr. Kristine Stump discussed these startling statistics during last week’s Bahamas Natural History Conference in Nassau. 

During the presentation, marine biologist Dr. Kristine Stump demonstrated that successive developers of the ongoing project, currently operated by Resorts World Bimini, have failed to use mitigation measures such as silt curtains while dredging and filling, sending plumes of dangerous silt into the lagoon, an important nursery ground for sharks, conch and lobster. The loss of important submerged mangrove habitat and accompanying siltation can have negative effects on the marine community, and results from her study showed declines in several important fish species that occurred after mangrove deforestation.

Local environmental advocate Joseph Darville, education officer for the fast-growing Save The Bays environmental advocacy movement, said he was overwhelmed by Stump’s presentation. “Save The Bays has been saying this all along. And now we have the proof, now we have the science. There can be no backtracking from here,” he said.

Save The Bays has been a strong advocate for the creation of several additional marine protected areas around the Bahamas, including a North Bimini Marine Reserve. “The most important step now is to prevent further loss by finalizing the long-awaited North Bimini Marine Reserve,” said Stump.  “By protecting what remains, there is hope that the lagoon can still function ecologically as a nursery for resources critical to the Bahamian economy.” Darville could not agree more. “The country has already lost significantly in Bimini, one of the most delicate and valuable ecosystems in the world,” he said.


The research presented by Dr. Stump used data on Bimini’s marine environment going back over 14 years to investigate the effects of habitat loss through mangrove deforestation.  It compared data before the development, originally known as Bimini Bay, to newly collected post-development information.

The findings indicated that due to the threat of predation outside the lagoon, juvenile lemon sharks remained in the nursery where they were born, despite severe environmental degradation and a drastic decline in available resources, including a more than 50% drop in their preferred prey.   In addition, there was a significant drop in species richness, a measure of biodiversity, after the development. “We found acute and chronic effects on not only the sharks, but also the entire marine community following the development within the lagoon,” Stump told the dozens of scientists and conservationists attending the conference.
