It involved a catchment comparison study using 4 of the Moutere experimental catchments, located 20 km southwest of Nelson. (...) The effect of riparian pasture retirement on water quality could not be unequivocally determined from the results of this study because water quality varied between identically managed catchments in the 1 year calibration study, and because water quality varied extremely in the control catchment between the calibration and treatment surveys. Furthermore, no firm conclusions could be reached regarding riparian pasture retirement effects on water yields. (...)
