This 2014 video is called Hazel dormouse. Соня орешниковая. Muscardinus avellanarius.
Translated from the Dutch ARK Natuurontwikkeling conservationists:
13 December 2015 – An investigation into the occurence of hazel dormice in nature reserves of ARK Natuurontwikkeling in South Limburg has been completed. In the young nature reserves and the immediately adjacent area 52 dormice were found. This result gives hope that in the future, if more shrubs will grow there, the dormouse‘s going to find more suitable places there.
The report on this is here.
