The forest dormouse ("Dryomys nitedula") is a species of rodent in the family Gliridae found in eastern Europe, the Balkans and parts of western Central Asia.
 It is categorized as being of least concern in the "IUCN List of Threatened Species" due to its wide range and stable population trend.
 Forest dormice have a diploid count (2n) of 48 chromosomes.
 Even though this species lives in a variety of geographic locations, its greatest population density is in the forests of central Moldova, in Transcaucasia, in the mountains of Central Asia.
 In most other locations, population density of this species is rather low.
 Population density is dependent on many factors.
 But the main features that this species depends on for choosing a location are the presence of the appropriate food sources as well as good foliage that can be used for a habitat.
 The reason why the forests in central Moldova have the highest population density is they provide the largest diversity of food sources which are available throughout the year.
 This location also provides the best type of foliage for the forest dormice to build their nests as well as swing from branches.
 The combination of both of these aspects allows for this species to have its highest needs met.
 Therefore, during mating season they produce offspring who also stay in the same general area when they mature.
 It makes sense not to move from an area if it is providing for your most basic needs.
