Assessment Methodology of Post-Relocation Dispersal of Mussels in a Natural River Setting after Construction Projects

Freshwater mussels are relocated during infrastructure and construction projects to reduce impacts to these species, as constructions projects are subject to state and federal environmental compliance requirements to avoid, minimize and mitigate impacts to threatened and endangered species. Mussel experts (malacologists) do not currently know where mussels are moving to after mussel relocations occur or why the mussels are moving. This project’s goal is to develop and validate a way to assess daily mussel movement in large river systems after relocation and during construction. The researchers will identify a technology to monitor mussel movement, quantify movement patterns and identify influencing factors after relocation. Outcomes of the project include a field-tested protocol for monitoring mussel dispersal, helping to inform future avoidance and minimization options on state transportation projects and the resulting consultation with the resource agencies.
