Assessing the European hedgehog’s (Erinaceus europaeus) status, behavioural activity and home ranges in a rurual and urban setting, with specific interest on the island of Jersey, UK


The European Hedgehog Erinaceus europaeus has seen population numbers decline for
several decades despite being listed as Least Concern on the IUCN Redlist. The quoted
46% reduction in individuals in 13 years has promptly had the species added to the UK’s
own Red List for species at risk of local extinction in the future. These regional declines
have led to studies reviewing hedgehog numbers on a more local scale, such as this study
on hedgehogs in Jersey, Channel Islands. Alongside analysing historical data stored at
multiple organisations in Jersey, this study included a radio-tracking survey undertaken
on the Island to assess behavioural changes in urban and rural-dwelling hedgehogs. Using
the latest Biotracker equipment, multiple surveys were conducted during initial activity
in the late evening and early morning hours. It is illustrated through visual observation
and statistical analysis that hedgehogs still have their favoured vegetational landscapes
to feed, seek refuge and hibernate in. However, due to the differing, ever-present
pressures in both urban and rural settings, it is not easy for them to settle in one location
for extended periods, with frequent and often fatal disruptions. This study explores ways
to mitigate these issues and suggests methods to support and bolster population numbers
in Jersey and across the continent.
