- •
Invertebrate and fish indices were predicted across whole river networks (110,000 km2).
- •
Models were done with the Random Forest analysis using 25 predictor variables.
- •
Invertebrate and fish metrics showed similar spatial patterns.
- •
All indices were mainly driven by the same environmental factors.
- •
Indices were higher in the Atlantic region than in the Mediterranean one.
