The non-native kelp Undaria pinnatifida (wakame) was found growing attached for the first time in late August 2024 in Kent on low shore chalk rock at Dumpton Gap between Broadstairs and Ramsgate. The species long-known to occur on marinas in Ramsgate Harbour was first recorded in Britain in the Solent in 1994 and has since spread to harbours and marinas in the south and east of England to East Anglia. In the west country permanent populations have established on rocky shores. Several thalli and many drift specimens were recorded at Dumpton and since then Tony Child of the Thanet has observed it on low shore rocks at sites at Ramsgate. Its appearance on our coast is where the decline of native kelp species has been recorded. Further visits are needed to ascertain whether a permanent population will become established.
