Habitat preferences and distribution of the brown rat (Rattus norvegicus Berk.) in the city of Salzburg (Austria): implications for an urban rat management

Abstract

The population of Rattus norvegicus was assessed using live traps and hair sampling tubes in 71 discrete patches distributed in the urban area of the city of Salzburg, Austria. R. norvegicus occurred in 35% of the examined habitats and reached a maximum density of 113.12 individuals/km along water banks. The occurrence of rats was strongly influenced by vegetation, habitat modification and man-made impact in the area. The results of this study could be used to support the development of a new, more scientifically based rat management plan in cooperation with the city of Salzburg.
