Two tropical forest fragments namely Ikot Efre Etak and Asanting community forests in Akwa Ibom State, Nigeria were assessed for the population and diversity index of plants producing valuable forest products. Appropriate ecological model were used to obtain the plant population density, Abundance/Richness index, diversity index similarity index. A total of 69 plant species comprising 41 species of trees, 13 shrub, 8 herbs, 4 climbers and 3 palms were encountered in the study areas. Apart from Canarium schweinfurthii (Linn.) and Mimusops heckelii (Linn.) with density of 11and 16 individual/ha respectively, all other tree species had a density of less than 10 individual/ha. Bambusia vulgaris (Schrad. Ex Wend.) had the highest shrub population density of 31 individual/ha, and in the herb category, Costus afar (Ker-Gawl.) and Hippocratea africana (Willd.) had the highest density of 53 and 11 individual/ha. Furthermore, the result also shows that Ancistrophyllum secondiflorum (P. Beauv and Wendl.) had the highest population density of 23 individual/ha in the palm category. The Sorensenís similar indexes for the two sites were Tree (41.46%), Shrubs (46.15%), Herbs (37.5%), Climber (50%) and Palm (33.33%). The study implied that The forest have extensively been degraded as a result of unsustainable exploitation. This has affected the plant population in the area. Community dependence on forest resource for their livelihood has drastically reduce the population of both flora and fauna species in the forest. Enrichment planting should be carried out for ecological restoration of the degraded area.
