M. dahli is known from a very restricted area, with extent of occurrence more than 100 km², but less than 5,000 km². Available habitat is fragmented. There is a river between the Turkish and Armenian part of the range, restricting dispersal. The Armenian population is known to be decreasing, current population size in Armenia is not more than 500-1000 individuals in total. The species occurs in sandy habitats and the main threat would be cutting of vegetation for firewood. It is a rare animal, assessed as Endangered (EN B1ab(ii,iii)). May also qualify as Endangered under Criterion C.

|Range Description:||This species is known only from local sandy habitats in the border area of Armenia and Turkey. Possibly Azerbaijan, because it was found near Sadarak village, which is near the border of Armenia and Republic of Nakhichevan (a part of Azerbaijan). In Turkey it is known from only one location (on the plain north of the Ağri Mountain) in Turkey (N. Yigit pers. comm. 2007, Demirsoy et al. 2006).The range consists of several separated areas. |
In 1960s total area of occupancy was less than 300 ha (Adamyan et al., 1976). In 1970-80 the area of occupancy sharply declined due to agricultural activity.

|Population:||In Armenia, estimates in the 1960s found 20 to 90/ha and in the 1990s, 2-5/ha in the 1990s. It is rare in Turkey (Demirsoy et al. 2006). In Armenia total number used to fluctuate from 500 to 6000 individuals (Dyatlov et al., 1987). More recently, Saakyan (Biodiversity Centre |
|Current Population Trend:||Decreasing|
|Habitat and Ecology:||Inhabit areas of hillocky, slightly fixed sands from 600 to 1000 m. In coastal sands lives among tamarisk shrubs with mixed grasses and herbs. In piedmont area dominate Calligonus and Achillea shrubs with mixed grasses and herbs. Feed on green parts and seeds of various plants. Winter supplies consist mainly of seeds. |
There are two types of burrows: permanent and shelter. Shelter burrows are simple and shallow, consist of one passage without widening. Permanent burrows are more complex, with 4-5 exits, passage length could be up to 7 m. Nest is at 0,5-2 m below the ground. In wintering burrow up to 5 individuals can hibernate.
Reproduction starts at the end of March - beginning of April. Gestation is 20-22 days. There are two reproduction peaks, in April and in July, however, adult females can have 3 litters per season. Litter size is 2-7, more often 4-6.
|Major Threat(s):||This is a rare animal restricted to sandy habitats with sparse, shrubby vegetation. It is susceptible to cutting of vegetation for firewood. Overgrazing and agricultural expansion are likely to threaten the population.|
|Conservation Actions:||In Turkey, the species is not in any protected areas, but there is one nearby (Agri Mountain N.P.). Listed as rare species in Red List of Armenian SSR (1990). In 1958 nature reserve "Gorovanskie peski" was established where Meriones dahli is one of the major protected species. More conservation measures for this species are urgently needed.|
