Look out for 12 kinds of seaweed to record in this survey. You don’t need to be an expert as our easy-to-use identification guide should allow everyone, from children to scientists, to take part.
By taking part, you will be helping scientists from the British Phycological Society and Natural History Museum learn more about these incredible, but often overlooked organisms.
The more information you send us, the more we can learn about this important group.
We will analyse your records. The results will help us understand where UK seaweeds can be found and how they are being affected by factors such as changing sea conditions, climate change and non-native seaweeds such as wireweed. We will also assess how seaweed distributions are changing.
Your data will be added to our online interactive map. As we analyse the data, we will post updates on what your records show and how they are being used.
