Abstract

The relative diversity and ecology of ferns the region of Skikda (North-East Algeria) were studied with the aim of documenting the pteridophytic flora and habit in this area. We have identified 25 taxa, one of this list is new to the Numidia sector (Pteris vittata L.). This flora is dominated by the rosale Hemicryptophyte biological type with either 60%. On the biogeographic level, we have 8 dominant subcosmopolite species, representing 32% of the studied flora. The rare flora of the region is presented by 10 taxa, 7 species considered as rare to very rare. According to habitat types, the species can be classified into 4 groups: terrestrials (20 species), lithophytes (11 species), epiphytes (1species) and aquatic plants (1 species).
