A sprawling low shrub found in a very wide range of mires and wet heaths, extending into drier heath in S.W. Britain. It is usually on wet, nutrient-poor organic soils, but can also grow in mesotrophic or eutrophic conditions. Generally from the lowlands to c. 670 m, but reaching 880 m in Coire Etchachan (S. Aberdeen).
E. tetralix was mapped as `all records` in the 1962 Atlas. Analysis of the database reveals that the widespread decline in S. England has taken place since 1950. In common with other heathland and bog species it has suffered from habitat loss, but it remains common wherever suitable conditions occur.
Suboceanic Temperate element.
