Abstract
Ghana as a country has developed many policy frame work and strategies to manage its wetlands. But one limitation in wetland management in Ghana is that the Ghana forest and wildlife policy covers only those wetlands designated Ramsar sites with no consideration to the minor wetlands. This study generally focused on the state of non-Ramsar recognized wetlands in the new Juaben Municipality with special reference to the floral diversity of such wetlands. The objectives of the research were to determine the species richness of flora in the Asokore and Osabene wetlands in with respect to species composition, species evenness and population density. Stratified sampling was used to select specific locations of 200m by 20m (400m2) within the study sites to carry out the study. The tools or materials used in the study were ecological tools such as 1m2 quadrant, line transect and point frame were used in sampling the plant species in the determination of species richness, species composition, and abundance. The sampled plant species were identified at the herbarium of the Department of Botany at the University of Ghana using reference for regional manual of flora. The data were analyzed using chi-square and Fisher’s exact test and t-test analysis where possible. Forty four (44) individual plant species belonging to twenty (20) families were sampled and identified at the two study sites each with Asokore having 31 of the species and 13 being observed at Osabene. The study has shown that there is correlation between species diversity and human interaction within the wetland since the Asokore with relative less degree of abuse was found to be more diverse than the Osabene wetland with quite higher degree of abuse.
