WETLAND ECOLOGY: SEASONAL VARIATIONS IN SELECTED PHYSICO-CHEMICAL PROPERTIES OF BHARMELA POND OF MENAR VILLAGE, DISTRICT UDAIPUR (RAJASTHAN), INDIADarshana Dave and Abhimanyue Singh Rathore
The present study deals with the seasonal investigations related to the certain physico-chemical characteristics of the wetland Bharmela located in village Menar (Rajasthan). The surface water samples for this study were collected during January, 2018 to December, 2018. The water quality parameters were tested following standard methods at preselected sampling site of the pond. The range of physico-chemical parameters observed for temperature was between 18.2-27.3 oC, for pH between 7.8-9.3, 70-80 ppm for the Total alkalinity, 7.3-9.4 ppm for D.O., 22.72-36.92 ppm, for Chloride, 1.00-2.00 ppm for nitrate, 28.0-38.0 ppm for sulphate and 0.05-0.10 ppm for phosphate whereas the depth of visibility during the study period ranged between 27.0-54.0 cm. The results of physico-chemical parameters indicate that water quality of this pond remained congenial for supporting good biological production at different trophic levels which obviously helps to attract several bird species from far distances. However, considering importance of this wetland as an important bird site, it is necessary to control influx of any type of waste and undesirable human activity in this water body.
