- •
The impacts of invasive species on river morphology remain largely unquantified.
- •
We analysed the spatial distribution and impact of signal crayfish on river banks.
- •
Burrows were associated with steep, bare banks and indicators of bank erosion.
- •
Excavation of (visible) burrows delivered on average 3 t km− 1 burrowed river bank.
