The soprano pipistrelle was only recognised as a separate species from common pipistrelle in the 1990s and depends on linear features near water.
Soprano pipistrelles face welfare threats from loss of linear features such as hedgerows and tree lines used for commuting and hunting. Building renovation that seals maternity roost access points can trap bats inside or prevent recolonisation. Light pollution discourages use of gardens and routes near buildings. Water pollution that reduces aquatic insect emergence reduces food availability along rivers.
