Inventory of the lichen flora of the national park of El Kala in northeastern Algeria

Abstract

The national park of El Kala (Algerian North east) is characterized by its genetic bio-diversity, so our work was carried on the evolution of lichenic flora in the three different zones: coastal, sub-coastal and mountains. We have used licheno-sociological combined method from the partial and integral classic method. 114 taxa have been counted with a particular abundance marked in the mountainous zone (representative species: Lobaria pulmonaria (L. Hoffm). Sub-coastal zone where the main phorophyte is Quercus suber (L.) is characterised by a crustaceous lichenic flora represented by the Lecanora kind. In the coastal zone, the representative phorophyte is Pinus pinaster (Ait.) with a dominance of crustaceous species (Candelariella).Of a global manner, lichenic flora in question has sub-cosmopolitan origin; its spatio-temporal follow-up is imperative notably in studies of impact and the bio-indication of the pollution.

Key words: Bio-diversity; Lichen; National Park of El Kala - northeastern Algeria.
