We often talk about the riparian zone and why it’s so important to aquatic life and one of the best plants for this zone is native grasses , they are better than trees at stopping the flow of nutrient from farm land particularly if they are planted in a thick blanket along the edge of the waterway about 20/30 metres wide.

This is a good example.
