Risk Assessment – Columbia River Basin Aquatic Invasive Species Database

Risk Assessment


Physical and biological habitat parameters can determine the ability of a nonnative species to establish, reproduce, or become invasive in a new aquatic environment. Knowing what areas within the Columbia River Basin are susceptible to invasion by invasive species of concern can improve the effectiveness of early detection programs and allow managers time to plan for mitigation, containment, control or eradication programs prior to the invasion.
