Field
|
Pacifastacus leniusculus burrows can reach high densities and can have a serious impact on bank morphology, causing them to collapse. It was considered to be a non-burrowing species, but in Europe it constructs burrows under rocks or in river and lake banks.

In the U.K., Pacifastacus leniusculus create burrows in riverbanks that can reach up to 0.87 m deep and reach densities of up to 21 burrows m^-1. These burrows can accelerate riverbank erosion and increase flood risk.
