Abstract

Damage caused by badger setts is an important source of human–carnivore
conflict in urban areas of the UK, yet little is known about the spatial distribution
of urban badger setts or their pattern of occupation. We compared the density,
spatial distribution and size of setts in four urban and two rural study areas in the
UK and assessed the applicability to urban systems of distinguishing between
‘main’ and ‘outlier’ setts. In addition, we used radio-telemetry to investigate
diurnal patterns of sett use in one urban area (Brighton). It was possible to
distinguish between main and outlier setts in urban environments, and local sett
densities were comparable in urban and rural areas. However, urban badgers used
substantially fewer setts than did a nearby rural population, and they spent a
smaller proportion of days in outlier setts. Social groups with larger ranges had
more setts available to them and, within groups, individuals with larger ranges
used more setts. Outliers appeared to serve multiple functions, including allowing
efficient and safe travel to important parts of the home range. We conclude that
sett densities can be high in urban habitats, suggesting significant potential for sett-related problems to arise. The fact that urban main setts can be distinguished from
outliers enables management actions to be tailored accordingly. In particular,
because main setts seem to represent a particularly valuable resource to urban
badgers, alternatives to the closure of problem main setts need to be considered
