Nyctalus lasiopterus
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
The Giant Noctule faces significant pressure from habitat loss as old-growth forests containing suitable roosting trees are cleared for agriculture and development across its European range. Wind energy installations pose an additional threat, as this high-flying species is particularly vulnerable to turbine strikes during migration and foraging flights. Climate change may be altering the distribution and abundance of its preferred prey species, large moths and beetles, while also affecting the timing of seasonal migrations.
Habitat
The Giant Noctule inhabits mature deciduous and mixed forests across Europe, particularly favoring old-growth woodlands with large hollow trees for roosting. During migration, it utilizes a variety of forested landscapes and woodland edges, often foraging over open areas adjacent to forests.
