Abstract:
The forest of Chettabah has the largest ecosystem of the Constantine region with an area of
2400 ha. Subjective sampling was conducted to analyze the vegetation and changes in species
composition of the massif.
The phytosociological analysis shows the presence of four plant communities belonging to
the class Quercetea ilicis (Pistaciolentisci-Quercetum rotundifoliae Dahmani 1997, Calicotomo
spinosae-Quercetum rotundifoliae Dahmani 1997, Cytiso salvifolii-Quercetum
rotundifoliae Dahmani 1997 et Clicotomo spinosae-Pinetum halepensis Brakchi 1998).
The vegetation dynamics is characterized by a regressive series with a matorralisation
progressing to therophytisation
