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.
