Woody plants in the last existing fragment of closed gallery forest in Delta du Saloum National Park, Senegal, were investigated by use of a 0.6 ha transect covering the main part of the gallery forest. There were 24 species and 369 individuals > 5 cm dbh with a basal area of 12.6 m 2 , 1062 individuals ≥ 1 cm dbh in 31 species, and 1730 individuals < 1 cm dbh in 29 species. Constrained clustering revealed six floristically distinct sections along the transect, and these sections coincided with structural differences. The vegetation in the study area is marked by degradation caused by frequent and intense fires coming from the surrounding savanna and by declining precipitation. However, the gallery forest is unique to the area and of crucial importance for conserving biodiversity. It can in the future be important as a resource‐base for restoration of the gallery forest system by means of natural regeneration.
