Here's why:
* Hedgehogs are found across Europe and parts of Asia: They are native to a wider region than just Britain.
* Their presence in Britain is likely due to natural range: Hedgehogs are believed to have migrated naturally to Britain, not introduced by humans.
* They are becoming less common in Britain: Sadly, hedgehog populations have been declining in Britain due to factors like habitat loss and roadkill.
So, while hedgehogs are a familiar sight in Britain, they are not exclusively British. They are part of a wider European and Asian ecosystem.
