Biodiversity and Conservation

Bridging physiology and ecology: the power of functional traits (Alizee Mauffrey)

A key aim of the BPS at its formation in 1952 was to record and map the seaweeds of the British Isles which culminated in Hardy & Guiry (2003), A Checklist and Atlas of the Seaweeds of Britain and Ireland.  We are increasingly concerned about changes to the seaweed flora due to climate change, increase in non-native species and a range of other factors. We are therefore keen to encourage you to help us with this challenge by uploading your seaweed records here.  Records will be verified by experts and shared via the NBN Atlas so that they can be used for research, education and conservation.
