Abstract

The floristic composition of Ayikunnugba waterfall forest was examined in this research study. The study area was divided into two compartments upper and lower compartments. The study areas were visited three times during the study periods. In this study, a total of 30 study plots of about 25 m x 25 m quadrats (500 sq m) size were established. About 15 plots were placed at the elevation 10 m a.s. at the lowest point of the waterfall and 15 study plots at the hilltop of 580m above the sea level.. Data were gathered from each quadrate. All the trees in the plot with the diameter at breast height (DBH) >lcm were enumerated, measured and identified. Also recorded were species name family which they belong and mean height. Important quantitative analysis such as density, important values and frequency of tree species were calculated. A total of 73 species belonging to thirty three families were recorded in the study area. The highest occurring tree species is Funtumia elastica with 32 individual's sampled. The highest DBH of 297cm was recorded in Milicia excelsa while the lowest DBH of 11cm was recorded in Khaya ivorensis Also the highest mean height of 35m was recorded in Ceiba pentandra and the lowest mean height of 5m was recorded from Xylopia aethiopica. Thirty-three families were recorded within the two blocks, Euphobiaceae has the highest number of tree species (7). The species density and species importance result indicate that Funtumia elastica has a density of (318) and the plant species with the lowest density was Khaya ivorensis which has 18. Funtumia elastic also has an important value of 2.133. The Shannon_H diversity index indicates that the lower block was higher (3.984) than the upper block (2.973).
