- •
Landscape configuration accounted for 48% of the total variation in water quality.
- •
The individual contribution of landscape configuration factors was 6.2%.
- •
A forest cover >47% is required to prevent the eutrophication of Canadian streams.
- •
In areas of intensive farming, high landscape diversity improves water quality.
- •
Woodlands with a complex shape (edge density >36 m/ha) benefit water quality.
