Occurrence and risk

The marsh club moss has a circumpolar distribution, it occurs in Eurasia and North America.

It grows on open raised bog soils in intermediate marshes, on quaking in peat bog in wet dune valleys and on anthropogenic secondary locations. It grows mainly on wet, moderately base-rich to acidic Torfschlammböden or on humus rich sand. Marsh club moss also rises higher to the montane altitudinal zone, in the Alps.

In Germany the marsh club moss is assessed overall as "at risk", but in many states it is considered a " high risk " or even " threatened with extinction ". In Austria it is " critically endangered " and lacking in Vienna and Burgenland. In Liechtenstein it is missing.
