AB Knowledge of Algeria’s orchid flora has increased considerably over the past two decades;however, certain regions, such as Guelma Province in northeastern Algeria, remain poorlystudied. Between 2013 and 2024, survey work was conducted in this region using asubjective sampling approach. A total of 40 stations were inventoried, and ecologicalvariables such as altitude, exposure, and vegetation cover were recorded to interpret thedistribution patterns of orchid taxa. In total, 37 taxa including 16 species, 19 subspeciesand 2 hybrids were identified, with a predominance of the genus Ophrys (19 taxa). Amongthese, ten taxa exhibit a close endemic relationship with neighboring North Africanterritories, and 22 are classified as rare in Algeria. Several taxa also appear as widespreadand abundant, enriching the known orchid flora of the study area. Multivariate analysesrevealed site typologies and environmental variables influencing the distribution of therecorded species. Cluster analysis identified five distinct Operational BiogeographicalUnits (OBUs), corresponding to specific environmental characteristics and orchidphysiognomies. Furthermore, correlations between the studied taxa and environmentalfactors suggest that their occurrence is strongly influenced by these variables. Given thehigh vulnerability of the surveyed sites and the increasing anthropogenic pressures theyface, the implementation of urgent conservation measures to protect these habitats andtheir components is strongly recommended.
