After years of painstaking research encompassing drones, satellite-based surveys and in-water surveillance from hundreds of different sites, we’re proud to announce the release of the Mangrove Report Card for The Bahamas!  This landmark report is a first of its kind assessment on the health of The Bahamas’ incredibly valuable yet often under-appreciated mangrove ecosystems.

So much more than swampy wastelands, Bahamian mangroves are economic and ecological superheroes.  They protect homes and infrastructure from tropical storms.  They support tremendous biodiversity above and below the water.  They fight against climate change by sequestering massive amounts of carbon dioxide.  And they provide nursery grounds for this country’s most sought after fishery species, including snappers and groupers. 

Along the water’s edge, red mangrove roots provide shelter for the young of many fish and invertebrate species that live on coral reefs as adults.

On the whole, this research shows mangroves are stable and fairly healthy throughout The Bahamas.  This is excellent news!

And yet, mangroves have taken a heavy beating in places hard-struck by major  hurricanes.  For example, Hurricane Dorian had a tremendous impact on the mangroves of Grand Bahama and Abaco.  The former lost 22% of its mangroves (nearly 14,000 acres) and the latter lost 14% (nearly 5,500 acres) to the deadly storm. In these areas, restoration is paramount to jump-start mangrove recovery and preserve their intrinsic and extrinsic value to the people of The Bahamas. 

A sneak peak of the novel information and data maps you'll discover inside the mangrove report card. Since the 1950s, many mangrove creeks have been lost or severely diminished in areas where extensive coastal development has taken place. New Providence, for example, has lost 37% of mangrove creek habitats since that time, largely due to clearing of trees, dredging and filling.

The Blue Project Foundation is a proud contributor to the making of this historic report card; we financed the field work and data collection for the entire west side of Andros!  We’d also like to thank the Perry Institute for putting this critical and timely report together, as well as their partners at The Nature Conservancy, Bahamas National Trust, Bonefish & Tarpon Trust and Waterkeepers Bahamas for backing this enormous and crucial research undertaking.  

This is a project of the Atlantis Blue Project Foundation.

Dr. Craig Dahlgren is a tropical marine expert and executive director of the Perry Institute. He is the lead author on the first-ever Mangrove Report Card for The Bahamas.

Sawfish off Andros Island

For the past three years, the team from the non-profit Saving the Blue has developed relationships with various community members in Andros, and so from October to December in 2021 they conducted interviews with fishing guides and other water users. Their aim was to describe sawfish distribution patterns in Andros, and identify key regions or habitats where sawfish monitoring would be effective, and potentially lead to protection.

Modern Miracle “M&M” splashes offshore of Bimini

We’re thrilled to announce M&M is as strong as ever! Just last month, one of his former caregivers and Dolphin Cay veterinarian Dr. Amanda Pinder photographed and identified him off the coast of Bimini – the two even posed for a quick photo together. Coincidentally, M&M was the first wild dolphin Dr. Pinder had ever treated more than four years ago.
