Following the publication of the article on the synthaxonomic study of the Dreat forest, the aim of this inventory of the Dreat forest’s flora (semi-arid zone in central Algeria) to allow us a quantitative analysis on the basis of biogeographic parameters such as specific richness, geography of distribution, endemism and rarity. A subjective sampling was carried out between 2018 and 2021 at the level of the various formations (forest, matorral, altitude grasslands, and steppe). This analysis showed considerable species richness, estimated at around 468 taxa belonging to 278 genera and 66 families. Therophytes dominate the other living forms, according to the defined biological spectrum. From a biogeographical point of view, Mediterranean species constitute more than 50 percent of the study area's species, followed by endemic species and rare.
