Traditional Seaweed Pressing
Seaweeds are vital to the health of our seas. They provide habitats for marine creatures, act as natural carbon sinks by absorbing carbon dioxide, and help fight climate change.
Seaweeds are also important indicators of environmental health. Changes in their growth and distribution often signal shifts in water quality, temperature, or pollution levels. By recording the seaweeds you find, you help monitor the health of our coastal waters and contribute to protecting these important ecosystems.
How to Participate
Adopt your Bay
Choose a bay, cove, or stretch of coastline that is meaningful to you

Identify and Record
Write the name of the species along with the date and location of each pressing.
Share your Data
Although you’ll keep your original pressings, you can share a photo and details of your findings with us through our iNaturalist community Project
