The Big Seaweed Search

Project is inactive

Seaweed in the UK is facing three major threats: rising sea temperature, invasive species and ocean acidification. As home to a globally important diversity of seaweed species, 'The Big Seaweed Search' was launched to track and understand changes in the UK's native seaweed distributions. You can help in this venture, by submitting your observations via an easy survey.

The UK is to a globally important diversity of seaweed species. Seaweed in the UK is facing three major threats: rising sea temperatures, invasive species and ocean acidification.

Since its launch in 2009, The Big Seaweed Search has engaged hundreds of participants, revealing shifts in seaweed distribution across the UK.

But they need more help to ensure these "forests of the sea," continue to provide habitats, food, and protection for marine life.

Whether a coastal resident or a visitor, everyone possesses the potential to contribute by submitting their observations via an easy survey.
