\textbf{Abstract}
\begin{abstract}
\normalsize{
Of many other benefits, wetlands are critical in cleansing polluted water. However, the rate at which they are being destroyed is alarming and hence a cause for concern. Attempts to solve these challenges in Kenya have not been successful since policy"=makers always demand tangible evidences to influence their decision"=making. Unfortunately, this information is not always available. This study attempted to fill this gap by conducting an explorative study in South-West Mau Forest on the role of riparian forests in reducing water pollution from adjacent land uses. The main objective of this study was to determine the effect of forest buffer on the water quality with Kaptebeng'wet wetland as a case. Although Kaptebeng'wet wetland is surrounded by tea farms, it has approximately 30 metres of indigenous forest buffer around its entry. However, the tea farms and other land uses have been developed right into the wetland towards the exit. Water samples were collected in June and September 2014 using standard methods and analysed for temperature, pH, turbidity, electrical conductivity, dissolved oxygen, nitrates and phosphates. Results indicated that the dominant plant species in Kaptebeng'wet wetland was \textit{Vossiens} spp. Further, there was significant spatial difference ($p < 0.05$) in temperature and turbidity between the entry and exit of the wetland respectively as follows: temperature 8.8 $\pm$ 0.19 °C and 9.8 $\pm$ 0.31 °C and turbidity of 0.60 $\pm$ 0.70 NTU and 11.76 $\pm$ 3.22 NTU. The wetland had nitrate levels of 1.55 $\pm$ 0.61 at the entry and 7.85 $\pm$ 2.97 at the exit and phosphate levels of 0.00 $\pm$ 0.00 at the entry and 12.25 $\pm$ 43.99 at the exit. This finding suggests efficiency of the indigenous forest buffer around Kaptebeng'wet wetland and the undisturbed wetland vegetation in nutrient uptake while the increased levels at the exit can be attributed to increased human activities downstream which disturbed the efficient functioning of the wetland. The study therefore suggests the need to develop riparian forests around wetlands if the important role played by wetlands is to be restored.}
