ABSTRACT
Plant diversity profile and water quality assessment in a recreational pond was investigated in March 2014 .A total of 20 plant species belonging to 17 families were identified in the study area. The results obtained showed that the species richness increased significantly (p= 0.05) away (< 5m) from pond. The pH value of the pond was found to be 5.06. Chemical oxygen demand was 12.80mg/l. Nitrate level of the pond was high, with a value of 12.51mg/l. Heavy metals found in the pond with high values were iron and cadmium ( 23.26mg/l and 4.5mg/l), respectively. The results obtained from this study suggests that the use of inorganic fertilizers and nutrient based around water bodies should be avoided as it results in acidification and eutrophication of the pond . It therefore shows from the study, that the use of the pond for recreational activities by the surrounding communities be discouraged as this may cause health hazards for humans and other grazing animals.
