Reports of wetland loss in New Zealand are typically related to the historical, pre-European
coverage of wetland ecosystems. It is widely accepted that large areas of wetlands were …

Pastoral farming on hill country landscapes influences nitrogen (N) dynamics and its losses
to freshwater. This study reviewed the current literature identifying key effects of pastoral hill …

Edge-of-field mitigations (EoFM) can reduce agricultural nutrient losses to surface water. To
determine the feasibility and cost-effectiveness of EoFM, we developed a spatial–economic …

The quantification of the nitrate attenuation capacity of pastoral hill country wet areas,
especially seepage wetlands, would aid in the proper management of hill country farms for …

Over the last 50 years freshwater and marine environments have become severely impaired
due to contamination from pathogens, heavy metals, sediment, industrial chemicals and …

Wetlands are a challenging mitigation to price as they are incredibly context specific, largely
depending on the amount of earthworks that are required. Two key types of wetlands are …

Naturally occurring seepage wetlands in hill country agricultural landscapes have the
potential to reduce nitrate leaching through denitrification. However, the effect of dissolved …

The presence of agricultural nutrients, particularly nitrate, in ground and surface waters is an
issue of increasing concern for the degradation of water quality in New Zealand. Thus …
