Many sites for E. multicaulis were lost in the 19th century, due to drainage and changes in land use. Since 1962, it has been lost from many more sites in E. England and E. Scotland. Conversely, this rather inconspicuous species is now much better recorded in the uplands, and it is known from over six times as many 10-km squares in Wales as in the 1962 Atlas.
Suboceanic Temperate element.
