-------

*Pupilla pratensis* is typical habitat specialist. It is a pronounced hygrophilous species, inhabiting open, richer, often [calcareous](/wiki/Calcareous "Calcareous") moist and wetland habitats. In Scandinavia it occurs in calcareous [fens](/wiki/Fen "Fen") and [meadows](/wiki/Meadow "Meadow"). The character of the sites in SE Norway (calcareous fen, sloping wetlands with springs) is in good accordance with this and with the habitats of *Pupilla pratensis* in Sweden; where it occurs as a typical species of open calcareous fens or wet, moist calcareous meadows. In Nordland County, Norway the habitats are of a different type, calcareous, rocky slopes close to the sea. Probably the wet climate in the western, coastal Norway makes it possible for the species to widen its ecological occurrence.

Unfortunately, this habitat type, treeless calcareous fens, is very rare, mostly isolated and nowadays highly threatened by draining and [successional changes](/wiki/Ecological_succession "Ecological succession") after the cessation of regular mowing and grazing. Therefore, the records are very important for nature conservation and much attention should be paid to extant populations.

The species’ ecology is similar to that of *[Pupilla alpicola](/wiki/Pupilla_alpicola "Pupilla alpicola")*.
