Seaweeds on the Beach
If you’re at the beach and you spot large amounts of seaweeds in the water or on the sand, let us know! We’ll use that info to monitor the situation. For more information and results of this project, please contact algasnapraia@ualg.pt Thank you for your collaboration!
What is the problem?
It`s normal to find seaweeds on the beach! But too many seaweeds may be an abnormal situation resulting from excess of nutrients from urban effluent discharge or fertilization in agriculture. When seaweeds grow in excess, they can harm biodiversity, fisheries and the environmental quality of the beach.
What can we do to help?
We’re studying excessive accumulations of seaweeds on beaches to look for future solutions. For this, we need to know more about them: what species of algae are they? When and where do they occur? Collaborate with us: send us information whenever you find seaweeds on the beach.
