Abstract

Many streams flowing through agricultural landscapes in New Zealand have poor water quality and biotic indicators. Loss of riparian zone function through vegetation removal and stock access cause changes. Farms where large numbers of cattle and red deer have access to streams result in degraded streams. Restoration of riparian zones and exclusion of stock from streams results in improvements but careful land management is also needed to ensure water quality and instream life is protected.
