This species is found in southeast Bulgaria through Thrace (Kurtonur and Ozkan, 1990) and western Turkey (Storch, 1978). The exact limits are unknown in western Anatolia, where the species is presently known from only three separate localities. The species was first described as a fossil species in 1937, and was only described as an extant species in the late 1940s. Subfossil information from southern Turkey and Israel indicated a larger range over the last few thousand years. The last published records in Bulgaria are from 1985.

Throughout its distribution the vast majority of suitable habitat has been converted to intensive agriculture, and the species' range is severely fragmented and subject to ongoing losses (SW Asia workshop 2005).
It is very difficult to determine what is happening with the range because it is the exact habitat preferences are not known. It has been declining since the Pleistocene. Only 50 animals are known in collections. The region in European Turkey and Bulgaria is intensively cultivated, with very little natural habitat remaining.
Roach's mouse-tailed dormouse
The Roach's mouse-tailed dormouse or ground dormouse, also known simply as the mouse-tailed dormouse, (Myomimus roachi) is a species of rodent in the Gliridae family. It is found in Bulgaria, Turkey and possibly extreme eastern Greece.
Historically found in Turkey and south-eastern Bulgaria. As oak and walnut trees were removed for agriculture and forestry its distribution became restricted to a few small spinneys in Edirne, north-west Turkey.
Roach's mouse-tailed dormouse lives in scrub and semi-open habitats with trees or bushes such as orchards, vineyards, hedgerows in arable land and river banks. Old trees are essential element in their habitat because it uses hollows of old trees to sleep during the day or rest for a little time at night.
The mouse-tailed dormouse is nocturnal which means that they are active at night. It is active from 1-2 hours before sunset til 1-2 hours after sunrise. The mouse-tailed dormouse is not strictly arboreal, it uses both trees and ground for moving and feeding. It also uses open areas such as grasslands, cereal fields and even recently plowed agricultural land for moving and searching for food, which makes it easier food for predators.The same animal uses few different trees with hollows for resting, and one tree can be used for one or more consecutive days. The same tree hollows are used by different individuals at different time.
