They face many constraints, in particular, that of invasion exotic species such as Nypa fruticans. The research aim consisted characterization Nipa palm traits Wouri estuary. study was carried out five points located main secondary streams River. Floristic statements were inside twenty-five plots 10 m x m, structural parameters number individuals, DBH, with equidistance 20m, installed sites. results showed has an occurrence 60 % studied higher density obtained inAkwa-nord 1309 individuals.ha-1 . leaves significantly differed between sampling (K= 6.91; p= 0.03); Youpwe site number. Stalk width also sites, from 25.2 cm Essengue 47.3 Youpwe. Factor analysis revealed more matures adults Youpwe, juvenile plants Essengue, seedlings Akwa-nord.
