Anyone who saw Wild Things on Channel 4 last night, with Trevor Dines of the BSBI, may be interested to see the current distribution of Danish Scurvygrass (Cochlearia danica) in Glamorgan. Undoubtedly the strongest populations are now along the M4 corridor; next spring take note of the profusion of these white flowers along the central reservation. This is quite remarkable considering the native range of this species is strictly coastal.
NB. The lack of dots along the eastern section of M4 is more to do with the lack of recording effort, as is the gap between Penllergaer and the Upper Loughor. The gaps in the NPT section are real as there are no soils in these sections.
