This research was aimed at assessing plants
diversity, under the influence of siltation and solid waste effluents along the
River Benue bank, Shinko area in Yola North Local Government Area of Adamawa
State, Nigeria. Three plots of 20 m × 20 m were randomly established at the solid waste, silt
solid waste, silted and no-silt; no-waste areas. A quadrat of 1 m × 1 m was laid at random to determine the population of
plant species in each plot. The results of the population of plant species in
the various sites revealed that, 10 plant species occurred at the solid waste
area (SWA), 7 species at silt waste area (SSW), 12 plant species at silted
area (SA) and 31 plant species at no-silt; no-waste area (NSW).
Shannon-Wiener’s diversity index was used to analyse species diversity in the
various sampling locations. Shannon-Wiener’s diversity indexes in the various
sites were approximately 1.985, 1.788, 2.140 and 3.125 at SWA, SSW, SA and NSW
respectively. The result obtained indicates high uncertainties; as each species are
relatively distributed within SWA, SSW, SA and NSW areas. The results indicated
that there were significant differences at P ≥ 0.05 as (p-value = 0.183377) in plant species
among the study sites. Axonopuscompressus had the highest occurrence in 3 of the study areas,
except for the silted area.
