There’s no evidence of Brown Hares (Lepus europaeus) living in the UK before Roman times and it has been suggested that the Romans introduced them. The UK’s only native hare is the Mountain Hare (Lepus timidus) which is quite common in Scotland and Ireland, and there’s also a colony in the Peak District. Unlike Brown Hares, the Mountain Hare’s fur turns white in the winter, apart from the black tips of its ears.
