ABSTRACT: This work is an evaluation of the plant diversity of the white Wormwood
formations (Artemisia herba-alba Asso.) in the steppes rangelands of the
south-eastern zone of Sa?da (municipality of Maamora, Western Algeria). For
this purpose, twenty-one phytoecological statements are carried out on three
sample stations: an exclosure station where the white Wormwood is well
developed and two other stations not protected where in one, the white Wormwood
is moderately degraded and in the other one, it is strongly degraded. The
factorial correspondences analysis (FCA) and the ascending hierarchical
clustering (AHC) carried out on the floristic and edaphic parameters measured
on these stations led to a hierarchy of the ecological factors determining the
diversity of the studied plant formations with white Wormwood. The vegetation
studied is marked by the dominance of the therophytes, particularly in the
third station (very degraded station), while the exclosure station is
essentially characterized by a high recovery rate and an important phytomass.
