First record of soprano pipistrelle (Pipistrellus pygmaeus Leach, 1825; Chiroptera: Vespertilionidae) in Wallonia (Belgium)

摘要

In absolute terms, most victims were reported from municipal roads. However, relative to the total length of roads within the range of the badger, most victims occurred on provincial roads. The number of traffic victims is significantly lower when mitigation measures have been in place for a while. The challenge for conservation lies in minimising victim numbers at provincial and municipal roads. As badger victims occur over a huge length of municipal roads mitigation along these routes will be difficult. Still, a number of measures are recommended, including for example placing fauna passages at well-known badger tracks, decreasing speed limits, relocating badger setts or closing roads for through traffic.
