Dormice Monitoring Programme
There’s a healthy population of dormice at Killerton and the rangers are working hard to ensure that our furry neighbours can thrive. Like bats, dormice are a good indicator of a healthy woodland habitat. There are 100 dormouse nest boxes across the estate, which help the team monitor the resident dormice.
Surveying the boxes
The boxes are surveyed once a month between April and October when the mice are active. We’re lucky to have some lovely hazel coppice stands around the estate, which are great places to look for evidence of dormice. While surveying the boxes, rangers will check the dormice, weigh them, sex them and take photos before returning them to the box, all without waking them.
Improving dormice habitat
Dormice like to be high among the tree branches, rarely coming to the ground, so the team at Killerton ensure that there are connecting branches high up. This means the dormice can move around on their treetop canopies during their nocturnal activities.
The small rodents also prefer ancient woodland and hedgerows – loss of this habitat is partly the cause for their declining numbers. So, here at Killerton, we’re looking after the hedgerows and ancient woodland to protect their home. We also make sure the woodlands and hedgerows all connect, so dormice populations don’t become isolated.
