Cumulative effects analysis of the water quality risk of herbicides used for site preparation in the Central North Island, New Zealand

Herbicide use varies both spatially and temporally within managed forests. While information exists on the effects of herbicide use on water quality at the site and small catchment scale, little is known about the cumulative effects of herbicide use at the landscape scale.

Aquatic fate of aerially applied hexazinone and terbuthylazine in a New Zealand planted forest

Herbicides are used to control competing vegetation during tree establishment, and are often critical to the productivity and economic viability of a planted forest crop. Despite increasing public concern over herbicide use in planted forests and potential impact on the environment, there is limited information on the aquatic fate of many of these herbicides when applied in forests according to standard operational procedures.
