Abstract: Invasive Alien Species are currently considered as the second leading cause of extinctions of documented species and the third threat to species at risk of extinction. This study assessed the invasive and non-invasive plant species composition and diversity in the Mangrove Ecosystem of Ibeno LGA, Akwa Ibom State, Nigeria. Two 10m x 10m transects were established within invasive and non-invasive stations using random sampling to evaluate species abundance. Data were analyzed for abundance, diversity, and evenness. Results identified 7 plant species belonging to 6 families, with Rhizophoraceae being the most abundant (42.9%). The invasive species found was Nypa fruticans. Non-invasive plants exhibited higher diversity (2.12) and evenness (0.360). The study concludes that both invasive and non-invasive species are present, but Nypa fruticans is progressively dominating the mangrove ecosystem, posing negative environmental, biodiversity, and socioeconomic impacts. Recommendations include raising awareness, promoting community participation, and enhancing research to manage the invasive species effectively.
