Peruvian Vale, Charlotte Parish, St Vincent, Saint Vincent and the Grenadines: there is significant sargassum seaweed problem along the coastline of Saint Vincent. Sargassum, a brown macroalgae, often accumulates in large quantities on the beaches, creating an unsightly and disruptive environmental challenge for the island. This environmental issue can create unpleasant odors, impede beach access, and potentially impact marine ecosystems and local industries like tourism and fishing.

Saint Pierre Island, Saint Pierre and Miquelon: Fucus vesiculosus, commonly known as bladderwrack, is a species of brown algae found along the coasts of the North Atlantic Ocean, including the shores of Europe and North America. It is characterized by flattened, branching fronds with distinctive air-filled bladders that help the algae float and optimize sunlight exposure for photosynthesis. Bladderwrack typically grows on rocky substrates in the intertidal zone, where it plays an important ecological role by providing habitat and food for various marine organisms. It has also been used historically in traditional medicine and as a source of iodine. Scientifically studied for its bioactive compounds, Fucus vesiculosus is relevant in both environmental and biomedical contexts.
