All the known Sefton sites for the British endemic Isle of Man Cabbage (Coincya monensis ssp. monensis) were visited in late May/early June 2015 and numbers of plants counted. At Crosby Marine Park, where sand was removed from a dune ridge for a 2011 coast protection scheme, 1361 plants were found on the extracted ridge while 211 were counted on the outer shore dunes that had been used as a donor site for a translocation in 2011.
A pattern of dry spring months has been evident for over a decade, March having only 65% of normal rainfall in England and Wales. An unexpected deluge came on 12th-13th but a small recovery in the height of the dune water-table in mid-month was subsequently lost. The ponds at Freshfield Dune Heath Nature Reserve remained extremely low but still attracted lots of Common Frogs.
