- •
First study to directly quantify the grazing activity of cattle with access to a wetland.
- •
The water quality effect of cattle grazing was monitored for 2 years.
- •
Cows did not spend much time grazing this deep (1–2 m) wetland.
- •
Wetland grazing only resulted in a small pollutant pulse on one occasion.
- •
Cattle exclusion from such deep wetlands is unlikely to improve water quality.
