St. Maarten – The Caribbean Hotel and Tourism Association (CHTA) is working with its 32 member hotel and tourism associations to provide hotels, government officials and stakeholders with best practice information aimed at mitigating the negative effects of high levels of Sargassum seaweed that has been reported at some local beaches.

The organizations have released a resource guide, compiled by the Caribbean Alliance for Sustainable Tourism (CAST), a CHTA initiative in collaboration with strategic partner OBM International to assist with local efforts.

Sargassum is a free-floating seaweed that moves with the ocean currents. It serves as a habitat for over 250 species of fish and invertebrates and is used by marine life as nurseries, feeding grounds and shelter. Sargassum can also be extremely important to endangered and migratory species like sea turtles and whales.

The guide is a useful tool for assisting hotels and destinations with developing a local action plan to manage and minimize the impact of Sargassum in an environmentally sensitive manner. “Sargassum is a natural occurrence that poses no known threat to beach goers,” a press release from the CHTA states.

That statement ignores the nuisance the weed causes to residents. Just this week, the French-side newspaper St. Martin’s Week reported about residents in French Cul-de-Sac who are unable to sit outside because of the stench and who experience all kinds of physical ailments as a result of the overpowering presence of the seaweed.

The CHTA’s resource guide also provides tips for educating hotel guests and residents about this natural phenomenon.

“This initiative is a prime example of CHTA’s strategy to collectively share knowledge, experience and best practices in an effort to elevate Caribbean tourism across all islands,” said Emil Lee, president of CHTA.

“We are pleased to see various levels of government, hotel and community collaborations already underway to manage the Sargassum impact. Tackling this effectively requires an even greater collective effort, with government policies and resources coming into play,” Lee stated.  The guide recommends local stakeholders to join forces and offers direction and resources to assist with their efforts.”

Citizens are urged not to remove the Sargassum using cranes and mechanical equipment because sand is removed as well as any marine life living in the seaweed. Following is a list of some alternatives and cleaning methods being used around the Caribbean that have proven practical and economical.

Leave or bury the Sargassum – Burying the Sargassum provides some relief as it works as an excellent medium for beach nourishment and can help combat beach erosion.


Manually transport the Sargassum – Collect the seaweed from the beach with rakes using wheelbarrows for low to medium amounts which allows cleanup crews to be careful of sea turtle nests that can be damaged by mechanical equipment.

Incorporate into landscaping – Sargassum can be reused once it is cleaned and dried, providing a nutrient-rich source of compost, fertilizer and weed control.

Organize beach clean-ups – A community beach cleanup helps accomplish the task. Many recycling centers take bags of seaweed.

Educate Residents and Businesses – It is important for the government to educate the residents and local businesses with reliable information to run a successful mitigation action plan.

Incorporate Sargassum in Culinary Preparations – In some cases, Sargassum can be cooked in lemon juice or coconut milk though the seaweed must be thoroughly rinsed and cleaned to make sure any foreign debris is removed. The most popular preparation is a quick fry, followed by simmering in water, soy sauce and other ingredients.

Contact local governments – Government officials should be contacted where there are amounts of Sargassum that are not manageable with the suggestion that it is treated as a natural disaster and government assistance be requested. Determination must be made as a nation if levels are considered to be a natural disaster and government assistance is necessary. This will be established on a case-by-case basis.

Although Sargassum poses no known threat to humans, if not addressed promptly it is not a welcome sight and an odor can quickly set in. The guide recommends that hotels and governments create a fact sheet about Sargassum to educate visitors and residents about its importance to the ecosystem and the logic behind removing it in an environmentally safe manner.

The guide provides a link to an online unique Sargassum tracking system through the SEAS program which assists with predicting where the seaweed may come ashore. This allows managers to provide accurate reports to guests as well as planning for clean-ups.
