We have already see dormice inhabiting some of the 300 nest boxes we set up around the Blackdown Hills this spring. The nest boxes have been regularly checked each month by volunteers and licensed handlers. At one site four dormice have already been found using the nest boxes.
The average dormouse litter size is four. These are typically born in July or August but litters may be born as early as late May or early June. Young dormice are weaned after about one month but may remain with the mother as juveniles, before they become independent and disperse. They must reach a weight of between 15-18g to survive the winter hibernation.
A big thank you to all the volunteers who helped us set up the nest boxes. For more information on dormice visit the People's Trust for Endangered Species (PTES) website.
