The Rusty Crayfish (Faxonius rusticus) is an invasive species from the Ohio River basin that has invaded Wisconsin’s lotic ecosystems. This species is known to impact it environment in many ways and this study is looking at the effect that it has on erosion. Rusty Crayfish were trapped at six locations with three of them being in areas with erosion and three being in areas with stable banks along with trapping them, water samples were taken from each site to determine if this crayfish has an effect on water measurements as well. This study found that Rusty Crayfish communities are present in areas with erosion and are absent in areas with stable banks, meaning that they do have some impact on erosion. This study also found that the areas they inhabit have a low velocity of the river which normally would mean this area should be gaining sediment not losing it to erosion meaning that they are actually causing some level of erosion to happen. The areas that they are not present in have a faster velocity but experience no erosion.
