Waterbirds monitoring is an important tool for characterize the functional role of marshes and to develop management methods for their sustainable protection. In Algeria, Mellah marsh is an exceptional site for waterbirds that forms the only eco-complex marsh - lagoon - Mediterranean Sea, but facing increasing levels of anthropization, which could damage its patrimonial value. This study aimed to evaluate the diversity and the structure of waterbirds stand and to compare the results with those obtained twenty years ago. The fieldwork was conducted during 2020/2021 period (from December 2020 to November 2021), where we conducted waterbirds identification and counts. We also realized, by remote sensing techniques, the detailed mapping of the study site, to highlight the evolution of land use around the site. The results shows a great land use changes, associated with the disappearance of 15 species, and an average decline of 81% of waterbirds abundance in the marsh, excepting for the Black- winged Stilt, the Eurasian Coot, the Great Egret, and the Little Egret, that have seen their populations increase substantially compared to those recorded in 2001. These results are preliminary data that confirm the incidence of anthropic factors on waterbirds diversity in Mellah marsh, and the need to develop management methods for their sustainable protection.
