Abstract

Despite the rising threat of Procambarus clarkii¸ or red swamp crayfish, in freshwater ecosystems, little is known about the factors influencing its introduction into lentic waterbodies. We hypothesize that human-mediated factors of introduction can help estimate where and how P. clarkii move throughout lentic waterbodies in Illinois and Michigan. To test this hypothesis, we created risk assessment models that estimate locations with the highest risk of P. clarkii introduction. In Cook County, Illinois, our model identified 1.4% of all waterbodies as high risk. These results can help concentrate management efforts on waterbodies with the highest risk of P. clarkii introduction.
