AboutThe hazel dormouse (or just 'dormouse') is an agile climber and mainly nocturnal, so is rarely seen. It lives in deciduous woodland, hedgerows and dense scrub, and spends most of the spring and summer up in the branches, rarely coming down to the ground. It eats buds, hazelnuts, berries and insects. Hazel dormice build nests out of grasses, stripped honeysuckle bark and fresh hazel leaves, in which the female will give birth to up to seven young. They hibernate during the winter months, either on the ground (under logs, leaves, in grass tussocks and at the base of trees) or just beneath the ground where the temperature is more constant.
How to identifyThe hazel dormouse has gingery-brown fur, large black eyes and a long, fluffy tail; it is much smaller than a squirrel.
In our area
To ensure a sustainable population and re-colonisation of nearby woods and hedges it is essential that we restore and strengthen links between woodland SSSIs.
In order to help dormice in Suffolk, it's important to know where they are. By recording any sightings or evidence of these legally protected mammals, from nests to nutshells, you can help keep Suffolk a dormouse stronghold.
