A study on Iroko’s regeneration was done under four seed-trees (two in a young fallow and two in a secondary forest). The aim was to know ecological factors what are influencing his spatial distribution and ecological recruitment pattern of juveniles under its seed-trees. Under each seeder, eight directions were selected according to the wind rose on 1 ha. The light, slope, and litter thickness were measured over the eight directions divided into 5m x 3m plots. For each found juvenile, its high and distance to the seeder were measured. Seventy-three juveniles were found, 47 in the young fallow and 16 in the secondary forest. More juveniles were found in young fallow under seeder 2 (28 juveniles) and few juveniles under seeder 3 in the secondary forest (5 individuals). Means of 23.5 ± 4.5 and 8 ± 3 juveniles were found in young fallow and secondary forest respectively. The overall average of juveniles per seeder was 15.75 ± 7.75 juveniles.
