Join the national seaweed hunt

Seaweed on rocks, Cornwall, UKNext time you visit the coast, take a look at the different types of seaweed that live there and you can help our scientists monitor the effects of climate change and invasive species.

Seaweeds are easy to find and occur all around the UK coastline. There are a staggering 650 seaweed species in the UK and they play a vital role in the functioning of the marine environment.

This weekend, the Natural History Museum, in partnership with the British Phycological Society and OPAL, launches its ‘Big Seaweed Search’.

Everybody can get involved. By simply recording the seaweed you find, you’ll help us learn more about our nation’s seaweed and the possible effects of climate change. You’ll also help us track invasive species such as ‘Wireweed’ which is slowly spreading through the UK.

“We are really interested in finding out more about the UK’s seaweeds and the public can help us gather much more data from all corners of the country. By understanding what’s happening to our seaweeds, we can find out more about the impacts of our changing seas on all marine life.”

All you need to take part is a ‘Big Seaweed Search’ survey pack which can be downloaded free from the Natural History Musuem website.

We hope you enjoy taking part!

The Big Seaweed Search is part of OPAL's work with natural history societies across England.
