Hedgehog Hibernation Survey

Main Project Information
Goal Understand how hedgehog hibernation relates to climate change.
Task Spot, record, share sightings of hedgehogs in the U.K.!
Where United Kingdom

A study was conducted 40 years ago which suggested a link between climate and when west-European hedgehogs (Erinaceus europaeus) come out of hibernation. Since the first year of this survey in 2012, over 90,000 hedgehog sightings have been recorded and we are starting to build up an invaluable picture of how British hedgehogs behave. This will inform our understanding of how hedgehog behaviour may change as the climate changes.

We need your help to collect hedgehog records from 1st February until 31st August 2014. Understanding patterns of hedgehog behaviour across the UK will enable us to target the conservation strategy for this charming animal, which is currently in severe decline.
