The lake is sur­round­ed by marsh­es, hills, and Jebel Ichkeul moun­tain, which ris­es to 511 meters. Its ecosys­tem is unique due to the sea­son­al bal­ance of fresh­wa­ter and salt­wa­ter. It serves as a refuge for hun­dreds of thou­sands of birds, includ­ing flamin­gos, geese, and storks. Despite eco­log­i­cal threats from dams and salin­i­ty, con­ser­va­tion efforts have helped pre­serve its bio­di­ver­si­ty.
