A large decline in numbers has occurred in the west of its range, especially in the Netherlands, where many nursery sites have been lost.

On a global scale the species is only near threatened, but detailed data from the eastern population is needed to draw reliable conclusions.

[1] In the summer this species nests in lowland regions with areas of water, meadows and woods, with winter roosts also occurring in the foothills of mountains.

Summer roosts are mostly in roof spaces or church towers, with individuals sometimes found nesting in hollow trees.

[citation needed] Most summer nursery roosts are in human buildings, typically in areas such as attics and church steeples.
