One of our rarest mammals is thriving in some of the most unlikely parts of Essex.
Dormouse numbers have dwindled dramatically in the last century but there are 35 known colonies in Essex and parts of Suffolk. Including one near the Greenstead housing estate in Colchester where they nest in the woody scrubland.
Did you know that dormice are so rare you need a license to handle them? Their habitat is being monitored by the Essex Wildlife Trust.
