Le lac Fetzara (Nord-Est algérien): Biodiversité floristique et menaces potentielles

Abstract

The wetlands of northeastern Algeria are rich in flora because of their biogeographical context. The Fetzara Lake, designated Ramsar site since 2002, has been the subject of multiple plant surveys conducted between 2014 and 2019 and has revealed the existence of 226 taxa belonging to 166 genera and 58 families with the dominance of therophytes (45.13%, 102 species). From the chorological point of view, the Mediterranean type was the most dominant with 128 taxa or 56.64% of the studied flora 19 of which are endemic to Algeria. Canonical analysis represented the superimposition of the three physiognomic environments of vegetation (dry lawns, amphibian meadows and semi-permanent lake) with respect to environmental variables. The results suggest that the distribution and variation of species abundance is mainly ordered according to salinity and grazing. These degradation factors therefore merit to be divulgated to arouse awareness of the public authorities and the population in order to implement appropriate protective measures.
