People visiting Tyntesfield House near Bristol usually learn about the family that has lived there over the years - but they are now being introduced to some of the other local inhabitants.
The team has been surveying and monitoring wildlife on the estate for many years, including, bats, newts and birds, but have recently extended their work to include dormice.
Volunteers have installed a number of nesting boxes around the woodland in order to provide a suitable home for this important but declining species. It is illegal to handle dormice without a licence so the discovery comes thanks to Tyntesfield volunteer Gill Brown who has one.
The mammals are very sensitive to weather and climate as they have specialised feeding requirements, surviving on flowers for nectar and pollen, fruits and some insects.
Tyntesfield’s dormouse was found in temporary hibernation in order to conserve energy, probably due to a lack of food. The rangers will continue to monitor them and see exactly how healthy they are.
Finding these rare creatures in the grounds of Tyntesfield makes it an important habitat nationally. Just as important, perhaps, as the house is to Britain's history.
