Big seaweed search

Add to My Folder

Join forces with the Natural History Museum and the Marine Conservation Society by helping them to monitor the effects of environmental change on Britain’s sealife.

All you have to do is explore the seashore and record the living seaweeds you find there.

The Big Seaweed Search first launched in 2009. Hundreds of people took part and the data gathered, alongside other research, showed that the distribution of seaweeds around the UK is changing.

Now they’re scaling up the survey to collect thousands of new observations and to focus on key environmental issues that need more research.
