A stoloniferous perennial herb of wet acidic sites, occurring in bogs, marshes, flushes and ditches, and on stream or lake margins. It spreads by wind-borne seed and by turions which form at the ends of the stolons and can be carried off by winter floods. 0-795 m (Foel Fras, Caerns.) and 845 m on Great Dun Fell (Westmorland).
E. palustre was mapped as `all records` in the 1962 Atlas. The current map shows losses, particularly in S.E. England, and analysis of the database reveals that most of these have occurred since 1950. These declines are probably due to agricultural improvement, drainage and eutrophication.
Circumpolar Boreo-temperate element.
