*2.1.2.3 Biogeographical framework*

The North African steppes in general and the Algerian steppes in particular are part of the Mauretano-steppe floristic domain defined by Maire [26]. This area belongs to the Mediterranean floristic region, therefore to the Holarctic Empire.

Biogeographically, the study region belongs to the Mediterranean area, to the highlands sector and to the Saharan Atlas sector according to the Quézel and Santa [27].
