|Scientific Name:||Allactaga tetradactyla (Lichtenstein, 1823)|
|Red List Category & Criteria:||Data Deficient ver 3.1|
|Assessor(s):||Gerrie, R. & Kennerley, R.|
This is a species with very specific habitat requirements, and a fairly restricted range along the coast of Egypt and Libya. There is likely to have been a loss of suitable habitat with the range of the species, which suggests that the population may have declined, but there is no information available to determine whether this species does indeed meet any of the criteria necessary to consider it as threatened. This is a species in urgent need of survey work and an assessment of the remaining habitat of this species is required.
|Previously published Red List assessments:|
|Range Description:||This jerboa species is found in coastal areas of Egypt and eastern Libya. It is confined to a northern coastal strip approximately 200 km wide and of less than 100 km inland (Abu Baker and Patterson 2010).|

|Population:||There is little known about the population of this species.|
|Current Population Trend:||Unknown|
|Habitat and Ecology:||Allactaga tetradactyla is found on salt marshes and clay desert areas of coastal plains. They are nocturnal rodents spending most of the daylight hours in underground burrows and emerging at night to forage.|
|Major Threat(s):||The species has a very restricted range that may be threatened by desert reclamation projects. The species' habitat may have been lost due to a severe drought in the coastal zone from 1995-2010 and an increase in tourism development, urbanization and agriculture (Alary et al. 2010). There has been a loss of salt marsh, barren land and rangeland to agriculture, urban and tourism development and quarries, but gravel desert has remained stable (Halmy et al. 2015).|
|Conservation Actions:||It is not known if the species exists in any protected areas.|
